Presentation of the SR50 Bus Rapid Transit Health Impact Assessment. The presentation includes elements of the SR50 Alternative Analysis conducted by LYNX
Guest presentation delivered by Gayle Wooton of Cardiff University, 25 November 2015.
Abstract: despite rising levels of urban mobility, access to places, activities and services has become increasingly difficult, particularly for the marginalised urban poor who face long distances or unaffordable travel costs in order to reach places of employment, education or leisure. In cities where access to private travel is uncommon, mass transport systems are essential elements allowing citizens to participate in everyday activities. Following successes in Curitiba and Bogota, mass transit systems such as bus rapid transit have been implemented in many Latin American cities (Medellin, Buenos Aires, Lima), while others are implementing metro systems (Quito, Panama City, Guadalajara, Santiago de Chile). Many such systems are unevenly distributed throughout the city however, with poorer neighbourhoods often poorly connected to the city centre where the majority of jobs and opportunities are located.
In tandem, many Latin American nations have been debating rights-based approaches to tackling social inequality. Ecuador and Brazil have adopted the Right to the City concept as part of their constitutions and Mexico City is developing a similar city charter. A human rights dimension is relevant to the provision of transport systems recognising that ‘the right to mobility is universal to all human beings, and essential for the effective practical realisation of most other basic human rights’ (CEMR 2007). Despite this link, rights-based approaches to social equity have not been studied in the context of mass transport systems. My research attempts to address to what extent rights-based approaches have been, or can be, integrated into decisions about mass transport investment, through the case study of Quito and plans for a new metro line and connecting metrocable routes. This presentation would present preliminary analysis following fieldwork in early 2015.

Tom Williams, program managers for TTI's Travel Forecasting Group, gave this presentation on a current research project at the 2016 Smart Transport Symposium held in Austin, Texas. This research explores the transportation planning implications of automated and connected vehicles (AV/CV) on Texas highways and includes an in-depth study of how travel modeling can assist in planning for AV/CV. The research team assessed how these potentially transformative technologies can be included in transportation planning to assist in the decision making process. The research team also defined AV/CV implementation along various scales of vehicle technology advancement, public acceptance and adoption, and infrastructure implementation.

Without curious minds, our transportation system would, quite literally, come to a standstill. In a very real way, the transportation research process keeps the system moving, and that process starts with a seemingly simple question: How can we do this better? Asking that question shines the light of innovation on the status quo to help make transportation safer, smarter and more efficient.
Our mission is to identify and solve transportation problems through research; to transfer technology and knowledge; and to develop diverse human resources to meet the transportation challenges of tomorrow.
TRANSPORTATION TODAY IS IN TRANSITION. Congestion is clogging our roadways, particularly in urban areas, wasting fuel, polluting air, and negatively impacting the quality of life for everyday commuters. Expanding economies are demanding more responsiveness from our transportation system to optimize shipping and squeeze every ounce of efficiency out of the bottom line. Yet many of our roadways, bridges and other structures are in dire need of repair.
This issue of the Texas Transportation Researcher looks at how Texas A&M Transportation Institute (TTI) researchers continue to solve problems plaguing our existing system while also planning how best to transition from the old to the new.
Creating Better Places with Transportation Demand Management (TDM)Mobility Lab
A “transit premium” can increase property values by anywhere between a few percentage points up to more than 150 percent.
TDM focuses on shifting travelers away from single occupancy-vehicle modes like biking, walking, bus, and rail. In many cases, however, TDM solutions and programs may address only a single alternative mode, or ignore the increasing diversity in how people – particularly younger generations – are traveling.
There is strong evidence of this narrow focus occurring frequently. Residential buildings may tout their WalkScore as a measure of pedestrian-friendliness. Or a commercial building may earn a Bicycle Friendly Business’ designation from the League of American Bicyclists. While these tools and designations are certainly valuable, sustainable buildings should have an an equitable distribution of transportation options and opportunities.
Most property owners and managers (and the business leaders who operate within them) can find ways to better promote and encourage a range of multi-modal options.
My contribution to helping them do so is the Multi-Modal Transportation Score (or what I like to call ModeScore for short). It measures the total accessibility of a given building, taking into account all possible sustainable transportation modes. My overarching goal is that building users will create and embrace programs to encourage and increase alternative travel.
The Texas A&M Transportation Institute (TTI) Transit
Mobility Program provides research and technology transfer expertise in all aspects of public transportation planning, management and operations. Program researchers bring a combination of direct operational skills in all bus and rail modes and nationwide research experience with metropolitan, urban and rural transit systems. Research projects result in practical, actionable recommendations for enhancing transit access, efficiency, effectiveness, safety and funding sustainability. Transit Mobility Program staff are adept at facilitating multi-agency groups in the development of shared transportation objectives, innovative strategies and coordinated services.
When The Texas A&M University System Board of Regents selected Dr. Dennis Christiansen as the Texas A&M Transportation Institute’s (TTI’s) fifth agency director in late 2006, the board tapped a seasoned leader, with 35 years of experience in advancing the national and international reputation of TTI already under his belt. In the subsequent 10 years that Christiansen served as agency director, TTI research expenditures increased by 60 percent, the total operating budget increased by 52 percent, and TTI facilities expanded from 216,000 square feet to more than 324,000 square feet — stellar accomplishments in the midst of changing research landscapes and funding cycles.

Presentation by Kevin Kokes, Principal Transportation Planner, North Central Texas Council of Governments (NCTCOG)
In 2009, the Texas A&M Transportation Institute (TTI) added a one-of-a-kind Visibility Research Laboratory to its collection
of world class research facilities. The laboratory is located in the Institute’s State Headquarters and Research Building in the Research Park at Texas A&M University in College Station, Texas. The laboratory features a 125-foot-long corridor that is used to test retroreflective materials and coatings, lights and other technologies designed to provide nighttime visibility for
highway drivers.
What is Truck Platooning?
Level 2 truck platooning extends radar and vehicle-to-vehicle, communications-based, cooperative-adaptive cruise control using precise automated lateral and longitudinal vehicle control to maintain a tight formation of vehicles with short following distances. A manually driven truck leads a platoon, allowing the driver(s) of the following truck(s) to disengage from driving tasks and monitor system performance. Level 1 truck platooning has demonstrated the potential for significant fuel savings, enhanced mobility and associated emissions reductions from platooning vehicles. Level 2 automation may increase these benefits while reducing driver workload and increasing safety.
The Transportation Revenue Estimator and Needs Determination System (TRENDS) model funded by the Texas Department of Transportation is designed to provide transportation planners, policy makers and the public with a tool to forecast transportation revenues and expenses based on a user-defined level of investment at both the state and local
level. The user, through interactive windows, can control a number of variables related to assumptions regarding statewide transportation needs, population growth rates, fuel efficiency,
federal reimbursement rates, inflation rates, taxes, fees and other elements. The output is a set of tables and graphs showing a forecast of revenues, expenditures and fund balances for each year of the analysis period based on the
user-defined assumptions. The TRENDS model also includes a local option sub-model for each of Texas’ 25 Metropolitan Planning Organizations. Through the local option model the user can analyze changes in local revenues by creating
or adjusting a local fuel tax, local vehicle miles traveled tax, local vehicle registration fee or the local fuel efficiency rates.
The Travel Forecasting Program at the Texas A&M Transportation Institute (TTI) supports and assists public agencies in the development, implementation and application of
current and emerging technologies in travel demand forecasting.
The purpose of travel forecasting is to help transportation
decision makers, at the local and state levels, improve the overall function of the transportation system. Program staff members accomplish this by developing travel models that predict future transportation patterns based on many variables. The variables used by program staff include comprehensive travel survey data, U.S. Census data, current and projected socio-demographic data, existing and projected transportation system data, and current traffic data.
The Texas A&M Transportation Institute (TTI) Transportation Planning Program conducts research on travel surveys, travel behavior and related data collection methods to support travel models, policy, and air quality analyses. Program researchers have expertise in travel data collection methods and technologies; survey design and sampling, data analysis and interpretation; demographic data preparation for modeling; and corridor management and preservation.
The TTI Center for Transportation Safety is home to a Realtime Technologies, Inc. (RTI) driving simulator that provides measurements of drivers’ responses to roadway situations, in-vehicle technologies, and driving-related tasks. RTI’s
SimCreator® and SimVista® software tools provide a library of different roadway cross-sections and interchanges, as well as a variety of roadway objects, buildings, and ambient traffic. In addition, custom roadway tiles can be programmed to match a specific roadway segment. This allows for in-house development of a wide range of rural and urban roadway scenarios, making it possible to inexpensively test multiple variations and placements of roadway devices or in-vehicle
signals and displays. Using the driving simulator, researchers can test a wider variety of roadway geometries and traffic conditions than are typically possible in a test-track study or fiscally practical in a field study.
The Texas A&M Transportation Institute’s (TTI) Sediment and
Erosion Control Laboratory (SEC Lab) provides the transportation industry with a research and performance
evaluation program for roadside environmental management. Research at the SEC Lab includes stormwater quality improvement, erosion and sediment control, and vegetation
establishment and management.
The Texas A&M University System is creating a new paradigm for the future of applied research, technology development and education. The 2,000 acre RELLIS Campus is conveniently located just 8 miles/15 minutes from Texas A&M University’s main campus. This location has long been a place where Texas A&M has conducted world-class research, technology development and workforce training in areas such as vehicle safety, traffic engineering, law enforcement training, biological materials processing, robotics and unmanned aerial systems.
Freight and passenger rail is a critical component of our nation’s
transportation system. Texas A&M Transportation Institute’s
(TTI) Multimodal Freight Transportation Programs Group
remains active in exploring the future of rail through a variety
of research activities.
Public scrutiny and agency accountability are at an all-time
high. Agencies are looking for a better understanding of the issues that are important to their customers. In an era of strained financial resources, it is necessary to order priorities that are important to the people that support the transportation system through taxes and fees. The Public Engagement Planning (PEP) program at the Texas A&M Transportation
Institute (TTI) provides research innovations and coordinated support to sponsors in the areas of public engagement planning and public opinion research.
The Texas A&M Transportation Institute (TTI) was asked by the Texas Department of Transportation (TxDOT) to assist in the application and refinement of prior research to accomplish some key goals during the reconstruction of the I-35 corridor from Hillsboro to Salado (90 miles total). Currently, TxDOT is conducting 10 construction projects along this corridor. More than 30 million drivers, including travelers, shippers and intercity commuters, use the corridor each year.
Intelligent transportation systems (ITS) include a broad range of services and technology solutions that provide and manage information to improve the safety, efficiency and performance of our transportation network.
Researchers design and implement experiments with human subjects (including field and simulator studies) and survey subjects to identify driver safety issues, such as those related to traffic control devices, distraction and fatigue. TTI’s experimental psychologists and industrial engineers have conducted numerous studies related to driver response to roadway geometric design; visibility and driver comprehension of traffic control devices; driver distraction; and automotive adaptive equipment for disabled drivers, older drivers and short-statured drivers.
The Human Factors Program is housed within the Center
for Transportation Safety at the Texas A&M Transportation
Institute (TTI). The goal of the program is to conduct basic and
applied research to measure driver performance and behavior
for varied driving situations, vehicle characteristics and roadway
environments. Researchers design and implement experiments with human subjects (including field and simulator studies) and survey subjects to identify driver safety issues, such as those related to traffic control devices, distraction and fatigue.
TTI’s experimental psychologists and industrial engineers have

For more than three decades, the Texas A&M Transportation
Institute (TTI) has been actively involved in the development
and improvement of the Texas Airport System. TTI’s contributions include activities related to planning and programming of airport projects, airport maintenance, and aviation education. TTI researchers have provided valuable guidance on a variety of issues to the Aviation Division at the Texas Department of Transportation (TxDOT) and to small and large airports across the state, including the Dallas-Fort Worth International Airport, Houston’s George Bush Intercontinental Airport and small airports such as Bryan’s Coulter Field.
The Texas A&M Transportation Institute is a leader in multimodal freight research and an innovator in exploring new ways of moving freight across the nation and around
the world.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features

EVERYTHING IS CONNECTED:
Research to Bring Public
Health and Transportation Together
By Kumares C. Sinha
Traditionally, transportation research has focused its
agenda on building the system to improve access to markets
and, more recently, meet the demands of a world economy.
With the highway system mostly in place, transportation
research is now focusing on enhancing system performance
and minimizing detrimental side effects. Some of those side
effects have reached the point of becoming serious public
health concerns.
Road crashes remain a major problem. In addition, the
reliance on automobiles for personal transportation has
resulted in less physical activity and less-active lifestyles,
contributing to an increasing incidence of obesity and related
diseases such as diabetes. The lack of access to medical
services for non-driving population groups is a growing
health care problem in many communities. Transportation’s
increasing environmental footprint resulting from congestion
and pollution has also added to adverse health effects.
Ignoring these issues negatively impacts the economy and
the quality of life in communities throughout the country.
Concerted research efforts are needed to face these challenges.
In view of the importance and timeliness of the rising
public health problem, the Transportation Research Board
Executive Committee held a policy session on this topic in
January. The purpose was to explore transportation’s effects
on health and disease and identify how to make the best use
of transportation to enable health improvements. Broadly
identified research areas included transportation and the
spread of disease, designing urban systems to promote health
and safe transportation options, enhancing access to health
care, improving road safety and reducing transportation’s
environmental footprint.

4. TTI Researchers Investigate Reasons
Impaired Drivers Choose Transportation
Network Companies to Provide Safe Rides
FOR YEARS transportation
safety officials have encouraged
impaired drivers to find a sober ride
home — be it designating a driver,
catching a cab or riding the bus.
Another option became available in
2009, when transportation network
companies (TNCs) first appeared.
TNCs provide on-demand taxi-like transportation via
self-dispatched independent drivers. Riders summon
drivers through a smartphone application that accepts
fare payments on behalf of the driver. Uber and Lyft
are two examples of this innovative approach to
supplementing traditional taxi services or providing new
options in areas where taxis are not available.
In a project titled Transportation Network Companies
and Impaired Riders: Reducing Impaired Driving
Through Passive Transportation, Texas A&M
Transportation Institute (TTI) researchers are exploring
the use of TNCs by impaired individuals. Preliminary
findings suggest that impaired people are using TNCs
rather than driving. What’s more, the core TNC ridership
represents the same segment of the population most
likely to participate in impaired driving. According to the
Fatality Analysis Reporting System, in 2013, the average
age of impaired drivers involved in a fatal crash was
36 years old. In the same year, 21 year olds were the age
group most frequently involved in fatal crashes. Among
those over the age of 18, the most common age group
served by TNCs is 25 to 34 years old.
Uber, one of the largest TNCs, serves 382
cities in more than 60 different countries
worldwide. Lyft is available in 206 U.S. cities,

safely after a night out drinking.
One such example is part of Austin’s
Get Home Safe campaign. With
proper documentation, the city will
wave the fee of a parking ticket if the
individual chooses another mode of
transportation to get home, instead of
deciding to drive after he or she has
been drinking.
Another example of policies that
incentivize impaired people to use
TNCs is providing a discounted rate to
those who use TNCs going to and from
their destination. So far these discounts
have typically been offered through a
partnership with an alcohol company
or professional sports team/league and
a TNC. One such partnership is Miller
Light Free Rides. The program was
launched in September 2015 to provide
free or discounted rides to prevent
drunk driving. The initiative involves
several modes of travel including Uber,
transit and taxis. According to the
website, the program has provided
more than 4.8 million free rides since
it launched.
“The end goal is to get would-be
impaired drivers to make an alternate
travel choice. Once we discover why
people are choosing TNCs over other
modes, companies or transportation
agencies can use incentives to
encourage that behavior,” says Elgart.
“Maybe that means making TNCs
more accessible to take round-trip.” ■

TTI Associate Transportation
Researcher Zachary Elgart explains:
“We know that impaired people are
using these TNCs to safely get home,
but we’re unsure of the decision
process that results in those individuals
choosing TNCs. For example, do
people arrange all their travel for a
night on the town with a TNC in
advance? That’s what we’re looking at
with this project.”
The growth of the industry is also what
makes TNCs a potential alternative to
other transportation modes. Uber, one
of the largest TNCs, serves 382 cities
in more than 60 different countries
worldwide. Lyft is available in 206
U.S. cities, and there are many other
companies that serve other areas.
Researchers will conduct focus groups
to obtain information regarding
people’s knowledge and use of TNCs.
The groups will be held in College
Station, Austin and Houston, and are a
little different than those for a typical
research project.
“We’re planning on recruiting
participants in areas with a high
concentration of bars and restaurants.
We want to make sure we’re reaching
our target audience,” says TTI Research
Scientist Eva Shipp. “The surest way to
do that is to go to the source.”
The project will also look at
programmatic and policy concepts
that encourage more people to
choose options other than driving
“The end goal is to get would-be impaired drivers to

As a means of improving safety at uncontrolled pedestrian
crosswalks, the Federal Highway Administration (FHWA)
has sponsored research on a variety of traffic control devices
intended to increase driver awareness and improve drivers’
yielding to pedestrians. One of the devices, the rectangular
rapid-flashing beacon (RRFB), has shown positive results —
an increase in the number of drivers yielding to pedestrians.
“The RRFB is very effective,” says Kay Fitzpatrick, manager
for the Texas A&M Transportation Institute’s (TTI’s) Roadway
Design Program. “A study conducted about 10 years ago found
that you had to have a device that showed a red indication
for drivers to yield at a high enough rate to be considered
acceptable. Now with the RRFB, there is a device with a yellow
indication where drivers are yielding at much higher rates.
Having this device only active when a pedestrian is present
is an obvious contribution to its effectiveness. We want to
understand what, if any, other characteristics are contributing
to the effectiveness.”
For many pedestrians, crossing a busy multilane roadway without the
protection of a traffic signal is a nerve-wracking, sometimes dangerous
proposition, even when using a marked crosswalk.
Rapid-flashing beacons with yellow indicators are proving effective at alerting drivers to pedestrians and, thereby, improving
safety at crosswalks. Having the device active only when a pedestrian is present contributes to that effectiveness.
“Several agencies are interested in having the RRFB
added to the Manual on Uniform Traffic Control Devices
[MUTCD],” Fitzpatrick explains. Before adding this device
to the MUTCD, however, refinements to its characteristics
were needed. An FHWA project conducted by TTI started
with a closed-course study conducted at the Texas A&M
University Riverside Campus that examined driver detec-
tion of a cutout pedestrian photograph in the presence of
light-emitting diodes with various brightness levels, flash
patterns and locations within the sign assembly. The results
from the closed-course study indicated that the flash pat-
tern and the beacon location justified additional investiga-
tions on the open road.
The research team used a staged pedestrian approach to
evaluate drivers’ yielding on the open road. Under this
protocol, a member of the research team acts as a pedestri-
an using the crosswalk to stage the conditions under which
driver yielding would be observed.

The TTI team developed a temporary light bar and control-
ler that permitted the research team to have control over the
flash pattern and brightness. Three flashing light patterns
were selected for use with the temporary light bars — the
pattern currently being used with other installations along
with two patterns developed by TTI in collaboration with
FHWA and other transportation professionals.
patterns (called WW+S) because it has a greater percentage of
dark time when both beacons of the RRFB are off (a benefit
identified in the closed course) and because the beacons are
on for less total time (resulting in energy savings).
“FHWA also wanted to investigate on the open road wheth-
er drivers would continue to yield at the same rates if the
beacon placement was different,” says Fitzpatrick. “We iden-
tified 13 test sites where the communities worked with us
and moved the beacons from below to above the sign. That
way we had similar drivers and site characteristics when we
collected data for both conditions — when the beacons were
above the sign and when the beacons were below the sign.”
The findings showed only minor, if any, differences between
the above and below positions (the average daytime yielding
for staged pedestrians was 64 percent for above and 61 per-
cent for below), and the statistical test showed no notewor-
thy difference. With the open-road study finding that driver
yielding is the same whether the beacons are above or below
the sign, and with the closed-course study revealing there
are benefits to having it above the sign, FHWA is planning
to issue an official interpretation that will allow agencies to
place the beacon above the sign.
“The findings from these FHWA studies are helping to
refine the device characteristics, resulting in a pedestri-
an treatment being considered for the next edition of the
MUTCD,” says Fitzpatrick. “More importantly, the device
is being used in more locations, and drivers are noticing the
rapid-flashing yellow beacons and yielding to pedestrians
crossing the roadway.” ■
The overall average
driver yielding for
each of the three flash
patterns was between
78 and 80 percent for
the eight sites in the
study.

“Sustainable transportation is an extremely broad topic that
has hundreds of different definitions and could mean different
things to different people,” explains Joe Zietsman, head of the
Texas A&M Transportation Institute’s (TTI’s) Environment and
Air Quality Division. “For some, it means the attempt to reduce
congestion with high-occupancy vehicle lanes or reduce greenhouse
emissions. For others, it’s wise land use and planning that makes
room for sidewalks and bike lanes. Sustainable transportation is
really a philosophy that should be incorporated into all aspects of
transportation practice and decision making.”

The connection between health and
transportation has now become
a strategic initiative at TTI. “We
are in the early stages of making
sustainable transportation a
priority. The concept is not going

the principle is here to stay.”
Joe Zietsman,
TTI Environment and Air Quality Division Head
VITAL TO ECONOMIC GROWTH,
transportation can also be a detriment to human
health and the natural environment. That’s among
the reasons why the concept of sustainable
transportation is emerging in countries around
the globe, among most state departments of
transportation in the United States and, in
increasing cases, as part of transportation
engineering curricula.

TTI’s Sustainable Transportation Research
Early TTI work focusing on sustainable transportation included a 2002
Zietsman-led project sponsored by the Southwest Region University
Transportation Center — Quantifying Sustainable Transportation
Performance Measures. The project goal was “to provide a framework on
how to identify, quantify and apply performance measures for sustainable
transportation in the transportation planning process.”
Six years later, in 2008, Zietsman and a team of TTI researchers developed
a performance-measurement approach to evaluate sustainability in the
context of the goals of the strategic plan initiated by the Texas Department
of Transportation (TxDOT) — reduce congestion, improve safety, increase
economic opportunity, enhance the value of transportation assets and
improve air quality. The team of researchers developed a methodology and
an analysis tool to evaluate progress toward sustainability.
The TxDOT project led the way for a national effort to help all state
transportation agencies identify and apply sustainability-related
performance measures. National Cooperative Highway Research Program
(NCHRP) Project 708, A Guidebook for Sustainability Performance
Measurement for Transportation Agencies, was completed in 2011 and
helped move sustainable transportation efforts to a new level. Zietsman
collaborated with numerous experts for the NCHRP project, which led
to a recently published textbook, Sustainable Transportation: Indicators,
Frameworks, and Performance Management (see sidebar). In 2014, Zietsman
used the NCHRP guidebook to help the Roads Authority of Namibia
develop a Road Transport Sustainability Plan for the nation’s transportation
network.

numerous people,
including three international experts
on sustainable transportation —
Henrik Gudmundsson of the Technical
University of Denmark, Ralph Hall
from Virginia Tech and Greg Marsden
from the University of Leeds.
The researchers decided it was time
for a full-length, detailed textbook on
transportation sustainability because
no such textbook existed. They met
for a week-long brainstorming retreat
in Yorkshire, England, to develop the
content for the book. The outline was
submitted to a book competition in
Denmark and won an international
award, which kept the effort
going. Four years later, their work,
Sustainable Transportation: Indicators,
Frameworks, and Performance
Management, was published. The book
became the basis of a well-attended
workshop at the 2016 Transportation
Research Board Annual Meeting in
January in Washington, D.C.
“It’s clear that sustainable
transportation is becoming a very
popular and relevant topic among
researchers and academia,” Zietsman
says. ■
Health and Transportation Projects
The connection between health and transportation has now become a
strategic initiative at TTI. The Institute has partnered with the Texas A&M
Health Science Center (TAMHSC) following a collaborative workshop last
year designed to examine future research opportunities. Two team projects
are now under way — one that links crash data with individual patient
outcomes (which could lead to improved treatments, faster emergency
responses and effective safety countermeasures) and another that evaluates
the health consequences of vehicle emissions along the Texas-Mexico border.
“Hidalgo County has among the highest rates of childhood asthma in the
state. Is it related to worsening air quality issues along the border?” asks Natalie
Johnson of the TAMHSC School of Public Health. “On the health side of the
project, we’re monitoring air pollution exposures of 25 expectant women
through blood and urine samples. But we need TTI researchers to help us
understand how the transportation sector is contributing to these exposures.”
The Strategic Research Development in Health and Transportation Initiative
will help to develop additional research opportunities between health profes-
sionals and transportation researchers. “We are in the early stages of making
sustainable transportation
a priority,” Zietsman says.
“The concept is not going
away. Terminology may
change, but the principle is

In the United States, more people live in suburbs than in central cities, and suburbanites
drive automobiles or rely on mass transit to get to and from work.
The construction of highways with multiple lanes and
faster speed limits has been a common response to meet the
growth of sprawling cities and the widespread ownership
of private automobiles. This increased reliance on roadways
has the unintended effect of creating additional demand and
worsening urban sprawl by encouraging distance between
residential and employment locations.
In most Texas cities, the options to walk or bike to work are
very limited, especially when you consider the ground most
travelers have to cover. But what if we had more options?
What would that mean for our health and quality of life? And
what would that mean for our transportation system?
Researchers at the Texas A&M Transportation Institute (TTI)
are examining the effects of active transportation on quality of
life. Active transportation refers to transportation modes that
primarily use physical activity to move from one destination
to another, usually by walking or bicycling.
TTI Assistant Research Scientist Ipek Sener explains, “It’s
well recognized that active transportation can be a solution
to a variety of transportation and health problems ranging
from congestion to obesity. But there’s an added dimension
to the story — when walking or biking, we have increased
opportunities to be aware of the people around us, interact
with our neighborhood, and be more attentive to our
environment.”
Walk, Don’t Drive
Active Transportation May Provide More Than Health Benefits
Designing more sustainable communities requires encouraging alternative travel modes.
“My research deals with humans who are
inherently affected by various emotional,
physiological and social factors, as well as
habits, inertia, attitudes and perceptions.
The first step in promoting active
transportation is to better understand an
individual’s choice to be active or not.”
Ipek Sener,
TTI Assistant Research Scientist
11. TEXAS TRANSPORTATION RESEARCHER 11
The majority of Sener’s research has focused on
understanding the factors influencing people’s activity-travel
behavior, and predicting how individuals would react to
different transportation, land-use and public-health policies.
Sener’s work has been published in several journals, including
her recent technical article “Potential Health Implications and
Health Cost Reductions of Transit-Induced Physical Activity”
in the Journal of Transport and Health. The article reviews
the associated health-cost benefits related to physical activity
and transit use. According to Sener, transit use is associated
with increased levels of physical activity and improved health
outcomes, but the extent of these effects is uncertain.
The goal of these articles is to improve researchers’
understanding of the link between health and transportation
in the context of various projects recognizing the benefits of
active transportation.
As part of a five-year collaborative project with The University
of Texas Health Science Center in Houston and funded by the
National Institutes of Health, Sener and her colleagues are
looking at how extending the Metropolitan Transit Authority
of Harris County’s light-rail transit (LRT) lines affects
the physical activity and travel behavior of Houstonians.
Researchers are examining the effect on low-income,
ethnically diverse adults residing along the new LRT lines.
Now in year three of the project, the team has completed
recruiting more than 800 participants and is collecting data
for follow-up phases.
“My research deals with humans who are inherently affected
by various emotional, physiological and social factors, as
well as habits, inertia, attitudes and perceptions,” says Sener.
“The first step in promoting active transportation is to better
understand an individual’s choice to be active or not.”
As part of a larger multimodal project for El Paso, Sener
and her colleagues are conducting several analyses to
better understand active travel behavior. They’re looking
at the factors, motivators and deterrents that influence
decision making. Sener also emphasizes the importance
of differentiating an individual’s needs and desires. “It’s
important that we recognize an individual’s constraints and
try to develop solutions for people who are willing to be active
but do not have the opportunity,” she says.
“When you look at the population in the El Paso area, we have
a very high rate of diabetes,” states Michael Medina, executive
director of the El Paso Metropolitan Planning Organization.
“And so if you’re able to identify a potential psychological
perspective of why [citizens] pick a certain form of transit,
what else would they need?”
Aside from the health benefits, other reasons exist for
promoting active transportation — congestion management,
air quality and energy dependency, to name a few. Fewer
cars on the road mean less congestion, cleaner air and fuel
conservation. We’re also running out of space to build new
highways, an ever-increasing and cost-prohibitive strategy to
expand roadway capacity.
Sener explains that due to the growing financial and social
costs of highway-oriented transportation, it is no longer
possible to simply rely on increasing roadway supply to meet
demand. That calls for developing new strategies that better
use the system we currently have.
“It’s essential that we look at alternative solutions in managing
demand and responding to the adverse impacts of highway-
oriented transportation solutions,” Sener says. “Active
transportation enters the picture at this point since it lies at
the heart of sustainable and integrated transportation systems
needed for a better future.” ■
Public transit, such as Capital Metro in Austin, Texas, is only
part of the solution. All modes — such as bike, pedestrian and
transit — must work together to promote mobility across our
transportation system.

We need to achieve greater mobility on our roadways, but we
can’t afford to build our way out of congestion. We need to
clean the air around urban areas to improve public health,
but policies enforcing clean air are difficult to pass and en-
force. In short, we need to do better with the system we have.
While we can’t afford to reinvent the wheel, we can make
it turn more efficiently with innovative thinking. How
we move freight — from ports of entry to, ultimately, the
market shelves in our biggest cities — is one part of our
transportation system that hasn’t changed much in the past
century. Ships offload international cargo, which is moved
via freight train and 18-wheeler trucks to the marketplace.
Today, almost all commercial cargo moving less than 500
miles is moved by truck, which causes significant con-
gestion on our roadways and contributes considerably to,
among other things:
• bottlenecks at border crossings, seaport regions and
major intermodal cargo hubs;
• air pollution from engine exhaust;
The Freight Shuttle System
Clearing the Air on Sustainable Freight Movement
• crashes; and
• road wear and the public costs associated with
repairing it.
And as economies expand (a good thing), the problem is
only getting worse. We need to move cargo smartly, cleanly
and safely. Enter the Freight Shuttle System (FSS), recently
noted as a “fascinating technology” that “could be a real key
to [the] overall discussion [of relieving congestion]” by Tex-
as Transportation Commissioner Jeff Moseley at the Feb. 25
Texas Department of Transportation Commission Meeting.
The FSS redefines how we move freight by its pioneering,
patented application of proven technologies. Designed
by Texas A&M Transportation Institute (TTI) Assistant
Agency Director Steve Roop, the FSS is a low-emissions
alternative to moving cargo and relieving congestion
created by trucks in heavy freight corridors.
“Not only will we help mitigate roadway congestion, we’ll
benefit the environment and public health while doing it,”
says Roop.
Doing more with less: that’s the mantra of transportation agencies
everywhere these days.
The Freight Shuttle System is energy efficient, using one-third the energy diesel trucks use at cruise speeds per vehicle mile traveled.
13. TEXAS TRANSPORTATION RESEARCHER 13
The FSS can move truck trailers and domestic intermodal
containers up to 53 feet in length — as well as all sizes of
ocean shipping containers — via emissions-free, electric-
powered transporters. The transporters ride on elevated
guideways in the medians of existing highways or other
rights of way over distances of up to 500 miles. Running
above existing roadways, the FSS transporters reduce the
number of trucks that would otherwise be hauling freight
over the highway.
Scientists have recently established a link between pollution
and airborne illnesses, particularly in highly populated
urban areas. While many other benefits accrue from this
freight-movement model, it’s the environmental (and
associated health) benefits that potentially hold the greatest
long-term contribution the FSS can make.
“Because we use electric rather than diesel power, our
carbon footprint is minimal,” explains Roop. “For example,
diesel trucks generate 43 times the nitrous oxide per vehicle
mile compared to the Freight Shuttle System.”
Powered by linear induction motors — with steel-wheel
technology that reduces friction and results in the
exceptionally efficient use of electric power — the system
can draw from any available source of energy, including
solar and wind power, to operate transporters along a
low-friction guideway. That conserves energy, minimally
impacts the environment, and provides reliable, continuous
movement of freight from point to point.
Many of our highways are near capacity, meaning a single
crash can back up traffic for miles. The FSS is designed to
FSS personnel test the prototype Freight Shuttle at the Test and Evaluation Center in Bryan, Texas.

operate on an automated, dedicated, closed-loop system
with custom-designed terminals and reliable scheduling
that produces congestion-free operation. GPS and wireless
communications, in conjunction with a fiber-optic
backbone, will provide a constant flow of information on
status, position and operating conditions to help ensure
maximum safety and efficiency. A single system could
operate up to 8,640 transporter trips daily in each direction,
with 10-second intervals between transporters.
The FSS is energy efficient as well, using one-third the
energy diesel trucks use at cruise speeds per vehicle mile
traveled. Once implemented, the FSS could reduce fuel
consumption by millions of gallons per year.
“If we’re able to introduce a more efficient alternative
to trucking in certain areas, we’ll see a corresponding
reduction in air pollution,” Roop says.
The FSS is currently in pilot testing at the 34-acre Test
and Evaluation Center in Bryan, Texas, as a joint project
among Freight Shuttle International, LLC; TTI; Curtis-
Wright Corporation; ZAMTEK, LLC; Figg Bridge
Engineers; Wells Engineering; Kapsch TrafficCom Group;
and Jones❘Carter, Inc. ■

The project, Automated and Connected Vehicle Test Bed to
Improve Transit, Bicycle, and Pedestrian Safety, is part of
the TxDOT Innovative Projects Program. In 2014, TxDOT
supplemented its Cooperative Research Program with the
Innovative Projects Program to proactively address issues
before they become problems and to explore applications of
rapidly evolving technologies.
“The goal of this project is to reduce the number of crashes
among transit vehicles, bicyclists and pedestrians,” says
Research Project Manager Wade Odell of TxDOT’s
Research and Technology Innovation Office. “Concerns
found in the research include buses making turns at
intersections or traveling in a straight line and negatively
interacting with bicyclists and pedestrians, as well as
distracted bicyclists and pedestrians not being aware of a
transit vehicle.”
In the beginning of the project, TTI held meetings and
workshops with modal stakeholders and conducted a
technology scan to identify four near-term applications,
three of which focus on collision avoidance with turning
transit vehicles, straight-line travel and fixed objects. A
fourth application is addressing bike-rack-on-buses safety.

COMMUNITY
From automated cruise control to Google self-driving cars to trucks
platooning, the world of connected, automated and autonomous vehicles is rapidly
evolving. A research project sponsored by the Texas Department of Transportation
(TxDOT) and conducted by the Texas A&M Transportation Institute (TTI) is
examining connected and automated vehicle applications to improve transit,
bicyclist and pedestrian safety.

k-turnbull@tti.tamu.edu, or Shawn Turner
at (979) 845-8829 or s-turner@tti.tamu.edu.
In the longer term, the research team
focused on the technologies associated
with moving toward autonomous
buses. The next step of the project is
developing the concept of operations.
“In developing the concept of
operations, we want to find out
what technologies might be used,
how you would operationalize those
technologies, and what the test bed
would look like,” says TTI Executive
Associate Director Katie Turnbull.
“During this phase, we discovered
that the Mobileye/Rosco Vision
Systems technology was available and
that they were interested in testing
their collision avoidance system in
a campus setting. We thought it was
a great opportunity to conduct a
small pilot project on the Texas A&M
University campus.”
Working in partnership with Texas
A&M University Transportation
Services, the Mobileye/Rosco
Shield+™ collision-avoidance system
was installed on one Texas A&M
University bus that traverses the heart
of campus, passing thousands of
students daily.
“The system has four different
cameras that are essentially aimed at
the blind spots on the bus and where
pedestrians and bicyclists are most
likely to show up and be in harm’s
way,” says Shawn Turner, head of
TTI’s Mobility Division. “What’s
special about this technology is that it
is able to detect when there’s an object
that’s moving that looks like a person
or a cyclist.”
According to Turner, one of the
big blind spots on a bus occurs
while making a turn. Two of the
cameras are positioned to eliminate
those blind spots, thus creating a
safer environment for the driver,
pedestrians and bicyclists.
“The nature of a large passenger bus is
that when it turns, it sweeps a big arc,”
notes Turner. “In other words it takes
up more space when turning. What

happens is people tend to walk out and
think of a car turning and not realize
they can’t get as close to a bus.”
The system provides two types of
warnings to the bus driver. A yellow
light goes off when a pedestrian or
bicyclist is detected within range of
the bus, alerting the driver to proceed
with caution. A red light and a buzzer
go off when a pedestrian or bicyclist
is very close to the bus, alerting the
driver to stop to avoid a possible
collision.
The research team is currently
assessing the system and developing
the overall concept of operations plan
for the test bed. A roundtable forum
was held on March 8 in College
Station, Texas, with representatives
from TxDOT, transit agencies, school
districts, cities and other stakeholder
groups. Participants had the
opportunity to ride the bus around
campus, see the system in operation,
and hear from Mobileye and Rosco
personnel on the system features. ■

Between 2011 and 2012, such crashes
involved an estimated 2,006 drivers
under the age of 26. In response to
the increase in crashes concurrent
with the oil and gas boom, the
Federal Motor Carrier Safety
Administration (FMCSA) put out
a high-priority call for proposals to
address the issue of novice driver
safety around large vehicles (e.g.,
commercial vehicles and buses).
Russell Henk, director of the Youth
Transportation Safety Program and
founder of the Teens in the Driver
Seat® (TDS) program, and his team
of experts were awarded $114,000
by FMCSA to encourage safe
interactions between teen drivers and
large trucks. TDS is a peer-to-peer
traffic safety program established
in 2002 based at the Texas A&M
Transportation Institute. Since its inception in Texas, TDS
has expanded to over 1 million student drivers in more than
1,000 high schools in 38 states.
“TDS already has the established statewide network to
reach out to teens in Texas,” explains Henk. “We can
easily coordinate with schools and use existing web/media
platforms to get the word out.”
The project is a web-based, hands-on outreach campaign
called Respect the Rig that shares truck facts, safe-driving
In the past three years, commercial motor vehicle crashes have increased 29 percent
in the Permian Basin and 55 percent in the Eagle Ford Shale regions of Texas.
tips, known crash risks and messaging that conveys respect
for truck drivers to the teen audience. TDS is coordinating
high-school safety fairs with the Texas Department of
Transportation and local police departments in regions
experiencing heavy truck traffic. The first event was
March 11, 2016, at Lyford High School in Lyford, Texas,
a town on the edge of the Eagle Ford Shale region. In
the coming year, TDS is planning similar events across
Texas to help young drivers become more aware of their
surroundings when big trucks are present.
“I feel that this campaign is a valuable tool in FMCSA’s efforts
to reduce crashes, injuries and fatalities on our nation’s
roadways,” says U.S. Department of Transportation-FMCSA
Programs Manager Rodney Baumgartner. “TDS’s peer-to-
peer model has proven very effective, and I thank everyone,
especially the teens, for their participation in, and support
for, this important program.” ■

Johanna Zmud at (512) 407-1140 or

A global research team, comprised of the Texas A&M
Transportation Institute (TTI), the Texas A&M Health
Science Center (TAMHSC) and transportation experts
from China, Germany, Japan and the United Kingdom, has
been assembled to study the issue. The project — Changing
Mobility Patterns of the Senior Generation — is sponsored
by the Institute for Mobility Research (IFMR), the research
arm of automobile manufacturer the BMW Group.
TTI Senior Research Scientist Johanna Zmud is leading the
consortium of experts, including Aging Specialist Marcia
Ory of the TAMHSC School of Public Health. The team will
examine historical travel patterns of the senior population
in their respective countries, determine what factors will
impact future driving behaviors, and produce simulation
models that predict future scenarios for senior drivers
through 2025.
“People are retiring later in life, which should mean they are
still commuting to work,” explains Zmud. “What impacts
will that have, especially as this trend continues?”
Of course, aging populations in different countries are not
all the same. For example, Japan has the longest average life
expectancy at age 84, the United States has 79, and China
has 75.
It’s no secret that we are living longer, healthier lives. But, does that also mean
we are driving longer and traveling more? If so, it could have a dramatic impact on congestion,
safety, public transportation and numerous other transportation issues — not only in the United
States, but around the world.
“It’s safe to assume that the amount of mobility is different
among countries as well,” Ory notes. “In some countries,
people rely on vehicles to get around, while in others people
walk a lot. My role is to provide country-specific aging
perspectives to the data.”
As they develop future mobility models for seniors,
researchers will also consider the changes in automotive
technologies — like automatic braking, blind spot detection
and collision avoidance — that could make it easier and
safer for seniors to drive.
“The elderly have always been a very important target group
for BMW Group products,” says IFMR Senior Researcher
Peter Phelps. “We need to understand how the mobility
behavior of this age group might change in the next 10 to
20 years to derive the right requirements for future
products, as well as mobility services such as car or ride
sharing.” ■

Led by the Texas A&M Transportation Institute (TTI),
a team of public agencies including the Texas Tech University Health Sciences
Center El Paso (TTUHSC El Paso) Department of Neurology, the El Paso Fire
Department (EPFD) and Mexican ambulance companies are conducting research
to speed up cross-border transportation for heart attack and stroke victims.
Mortality rates increase sharply as time increases from incident to treatment,
but quickly getting patients the care they need is sometimes challenging with
tightened security measures at the border.
Evaluating Ambulance Cross Border
Operations and Its Impact on Public
Health in Border Regions is a project
funded by TTI’s Center for International
Intelligent Transportation Research
(CIITR) and TTUHSC El Paso. The
ultimate goal of the project is to
establish an operational protocol to
expedite ambulance cross-border
operations in the El Paso–Ciudad Juarez
binational region.
“We are in the early stages of
conducting meetings with all the
stakeholders. We’re looking at current
operational protocols and determining
where the process can be streamlined
to get emergency patients to El Paso
hospitals quicker so treatment can
begin earlier,” says David Salgado, TTI
associate transportation researcher for
CIITR and principal investigator on the
project.
Currently, when a patient suffering a
stroke or heart attack is transported
from Juarez to El Paso, Mexican
ambulances carry him or her to the
border, where the patient must have the
proper paperwork to cross. Once cleared
by CBP, the patient is transferred to an
EPFD ambulance that takes him or her
to a U.S. hospital. In cases where the
proper paperwork is missing, a border
agent must ride with the patient to the
hospital until the individual’s status is
confirmed.
“Stroke is the number one cause of
disability in the United States,” says
Gustavo Rodriguez, M.D., TTUHSC
El Paso neurologist. “It is imperative
that stroke patients be treated quickly
with a specialized clot-busting drug.
Otherwise, the patient can suffer
permanent damage.”
“Part of the delay occurs because,
currently, CBP is not notified that an
ambulance is en route to the border
with a patient,” Salgado says. “Perhaps
a pre-notification process can be
established in which not only is CBP
notified, but so is EPFD. Consequently,
Mexican ambulances, CBP, and EPFD
are fully coordinated and aware of the
situation in real time.”
Researchers are currently studying how
many patients are being transported
and the magnitude of the delay problem.
To that end, other stakeholder meetings
are being planned, as well as a workshop
to outline recommendations.
“If there is a weak link in this process,
we need to find it,” says Lt. Oscar
Salazar of EPFD. “If the border is part of
the problem, we need to fix it. We want
to make this as seamless as possible.” ■

Former TTI Agency Director Named
Texas A&M Distinguished Alumnus
Wootan joined TTI in 1956 as an associate research
economist and served as the Institute’s associate director
(1966–1976) and director (1976–1993). Under his leadership,
TTI grew to become the largest university-based
transportation research agency in the nation.
Charley V. Wootan, former Texas A&M
Transportation Institute (TTI) agency director,
was named a distinguished alumnus of Texas
A&M University March 11 by the Association
of Former Students.
Former TTI Director Charley Wootan and two other TTI
economics researchers Bill Haning and Hoy Richards examine
selected economic impacts of highway projects to evaluate the
consequences of constructing new highways. TTI researchers
examined land use and values along freeways and rural
stretches of highway.
“I had the privilege of knowing and working with
Charley Wootan for three decades,” says TTI Agency
Director Dennis L. Christiansen. “He was a giant in the
transportation field who tirelessly promoted the value of
transportation research and made significant contributions
to the growth and national reputation of TTI. He was a
devoted Aggie who gave selflessly of his time to improve the
world through research, education and service to others.
This honor is well deserved.”
One of the founders of the Council of University
Transportation Centers, Wootan was selected as its first
president. He was actively involved in the Transportation
Research Board (TRB) of the National Academies for more
than 40 years and was elected chair of TRB in 1979 and
again in 1983. He also served on the executive committee
of the American Association of State Highway and
Transportation Officials.
Wootan led the way for Texas to become a national model
for how universities and state departments of transportation
could work together to solve transportation problems. The
path he forged remains the model that other states emulate
today. He tirelessly contributed thousands of hours serving
in state and national leadership roles on committees and
task forces established to improve transportation throughout
Texas and the United States. He won numerous awards
for his contributions, including the TRB Distinguished
Service Award, the George S. Bartlett Award for outstanding
contributions to highway progress, and the Luther DeBerry
award for significant accomplishments to Texas transportation
from the Texas Department of Transportation.
Wootan actively mentored young people and promoted
education as the path to professional success. More than 2,000
Texas A&M students studied in TTI laboratories and worked
on TTI research projects during his tenure at TTI. ■

Fitzpatrick and Assistant
Research Engineer Mike Pratt with a Committee Paper Award.
Their research analyzed driver and pedestrian behaviors at
pedestrian hybrid beacons (PHBs) and revealed that 96 percent
of drivers yielded to pedestrians when the PHB was activated,
a number comparable to those who yielded to traffic control
signals. A greater number of pedestrians activated the PHB
when on 45-mph posted speed limit roads as compared to
roads with posted speed limits of 40 mph or less.

TTI NEWS
The Federal Highway Administration
(FHWA) Office of Safety (HSA) has selected
TTI for a major multiyear, multimillion-dollar
contract for research aimed at improving
transportation safety related to everything
from highway design to bicycle/pedestrian
safety and speed management.
“TTI is leading a team with 10 subcontractors,” says TTI Senior Research
Engineer Paul Carlson, who’s leading the project. Carlson, head of TTI’s Traffic
Operations and Roadway Safety Division, is recognized as one of the nation’s
premier researchers in visibility safety. For example, he was one of five
national experts invited to address FHWA’s 2014 workshop on transportation
visibility held at the FHWA Turner-Fairbank Highway Research Center in
McLean, Virginia.
“We’ve leveraged our national reputation in the transportation safety arena to
provide FHWA with innovative ideas and solutions to enhance transportation
safety,” adds TTI Senior Research Engineer Karen Dixon, co-principal
investigator on the project with Carlson.
TTI was the only university-led team awarded a contract. TTI’s team
includes faculty members from Texas A&M University’s Dwight Look
College of Engineering and extensive training expertise from the Texas A&M
Engineering Extension Service. The team will collaborate and assist HSA with
policy and regulatory analysis, technical studies, guidebooks and training
support, as well as outreach and marketing support.
“This significant contract is another example of how The Texas A&M
University System coordinates across the university and its agencies to take
a leading role on issues facing not only Texas but the entire nation,” notes
A&M System Chancellor John Sharp.
TTI Agency Director Dennis L. Christiansen agrees, adding, “Our safety
researchers are eager to begin the life-saving projects that will be awarded
during the length of this contract. Their expertise in transportation safety is
well known throughout the country, and their role as team leaders on this
national contract is well deserved.” n

Polunsky Receives Straub Award
TTI Research Scientist Steven Polunsky has received the Curtis H.
‘Butch’ Straub Achievement Award, given to one student in each Naval
Postgraduate School Center for Homeland Defense and Security (CHDS)
class. Developed in 2002, the class assists “current and future leaders
in homeland defense and security to develop the policies, strategies,
programs and organizational elements needed to defeat terrorism in the
United States.” Polunsky received the award, which is based on grades, a
thesis and classroom leadership, during a ceremony Dec. 18 at the Naval
Postgraduate School in Monterey, California.
“I’ve always had an interest in emergency response and homeland security,
especially in how they relate to transportation,” Polunsky says. “Our
transportation facilities are critical infrastructures. There are numerous facets
to this problem, and we need to identify and address vulnerabilities.” n
