The document discusses the I-95 Corridor Coalition GIS Project, which created a consolidated multi-state road network database by integrating individual state road centerline databases along the I-95 corridor. Significant challenges included differences in data quality and attributes between states. While useful for initial analysis, regularly updating the integrated database is difficult. Future efforts may be improved by starting with a commercial network or focusing only on core attributes.
NFTA Metro Route Restructuring
Presented by: James Morrell, Manager, Service Planning, NFTA
Hal Morse, Executive Director, Greater Buffalo-Niagara Region Transportation Council
The Niagara Frontier Transportation Authority (NFTA) implemented a major route restructuring
initiative on October 31, 2010; a plan which required extensive organizational planning and community participation. The restructuring included adjusting service levels to make the entire system more efficient and increase passenger revenues. Buses now run more frequently over the heaviest used routes, and less frequently over lesser-used portions. This presentation will outline the steps needed to restructure service to be more efficient and cost effective.

Google Transit and the widespread adoption of the General Transit Feed Specification (GTFS) has had a huge impact on the availability of Transit routing and scheduling services and information,
both from Google and third parties such as HopStop.com. The effect has been to provide
the public with high-quality information services (well beyond what was imaginable a decade
ago) while lowering the cost to transit agencies. In his presentation, Mr. Ziering will tie together a
number of transit-related information systems projects that are now in progress or have recently
been completed by Cambridge Systematics that illustrate this theme of cost-effectiveness through
the innovative use of information technology. Together, these projects showcase the potential to
maximize the effectiveness of existing transit agency resources through innovative use of information systems.

Lessons Learned in Transit Efficiencies, Revenue Generation, and Cost Reductions
Presented by: Joel Volinski, Director, National Center for Transit Research, University of South Florida
Over the years, transit systems have responded to budget challenges by becoming more diligent
and creative in developing ways to generate non-traditional revenues and to reduce costs without raising fares or cutting service. Mr. Volinski will discuss a project, first reported on in 1996, whose objective was to collect innovative ideas from transit agencies throughout the country. The ideas collected were then synthesized and redistributed to transit agencies throughout the nation, allowing all agencies to have the potential to replicate successful techniques. Mr. Volinski will also provide a sampling of the 200 successful ideas that have been put in place in dozens of transit agencies across the country.

The Florida Department of Transportation, District Seven has developed a strategic plan for freight mobility in the Tampa Bay region to support economic development and capitalize on the
new trade environment that includes the growth of the region as a distribution hub, the expansion of the Panama Canal, and the eventual opening of free trade with Cuba. The Strategic Freight
Plan includes a policy framework to guide the identification of investment strategies and roadway design that support the primary corridor function and are compatible with the land uses and
associated activities within travel corridors in the region.
This presentation is designed to provide a more detailed look at the transportation investments envisioned for each scenario. It also includes some analysis and information presented at the citywide transportation workshop. This is intended to provide more detailed information, and isn’t necessary to complete the survey.”
A New Paradigm in User Equilibrium-Application in Managed Lane PricingCSCJournals
Ineffective use of the High-Occupancy-Vehicle (HOV) lanes has the potential to decrease the overall roadway throughput during peak periods. Excess capacity in HOV lanes during peak periods can be made available to other types of vehicles, including single occupancy vehicles (SOV) for a price (toll). Such dual use lanes are known as “Managed Lanes.” The main purpose of this research is to propose a new paradigm in user equilibrium to predict the travel demand for determining the optimal fare policy for managed lane facilities. Depending on their value of time, motorists may choose to travel on Managed Lanes (ML) or General Purpose Lanes (GPL). In this study, the features in the software called Toll Pricing Modeler version 4.3 (TPM-4.3) are described. TPM-4.3 is developed based on this new user equilibrium concept and utilizes it to examine various operating scenarios. The software has two built-in operating objective options: 1) what would the ML operating speed be for a specified SOV toll, or 2) what should the SOV toll be for a desired minimum ML operating speed. A number of pricing policy scenarios are developed and examined on the proposed managed lane segment on Interstate 30 (I-30) in Grand Prairie, Texas. The software provides quantitative estimates of various factors including toll revenue, emissions and system performance such as person movement and traffic speed on managed and general purpose lanes. Overall, among the scenarios examined, higher toll rates tend to generate higher toll revenues, reduce overall CO and NOx emissions, and shift demand to general purpose lanes. On the other hand, HOV preferential treatments at any given toll level tend to reduce toll revenue, have no impact on or reduce system performance on managed lanes, and increase CO and NOx emissions.

Transportation for the Nation
Case Study – I-95 Corridor:
I-95 Corridor Coalition GIS Project
TFTN Strategic Plan Case Study
2. Overview
In support of the I-95 Corridor Coalition, Cambridge Systematics is coordinating
the development of a Corridor-wide information system that consolidates
existing state roadway network databases into a single multi-state roadway
network to guide regional transportation planning and emergency
management efforts. This work includes the Integrated Corridor Analysis Tool
(ICAT).
The consolidated road network is comprised of the ‘best publicly-available’
road centerline databases from each of the 16 states and the District of
Columbia, who are members of the I-95 Corridor Coalition. The individual state
roadway databases are ‘stitched together’ at the state borders to form a
topologically integrated network that can be used both for network analysis
and for overlaying other data of interest, such as crashes, traffic, roadway
conditions, and planned improvements. The consolidated road network also
includes a set of core attributes that are common across all states.
Project Background
Interstate 95 (I-95) is the main north-south Interstate highway on the eastern
coast of the United States, along the Atlantic seaboard. It is 1,925 miles long
from Houlton, Maine;—the border crossing with Canada—to Miami, Florida. It
passes through 15 states—Maine, New Hampshire, Massachusetts, Rhode
Island, Connecticut, New York, Pennsylvania, New Jersey, Maryland, Delaware,
Virginia, North Carolina, South Carolina, Georgia, and Florida—and the
outskirts of the District of Columbia.
The I-95 Corridor Coalition is a partnership of 16 state DOTs—the 15 mentioned
previously, plus Vermont, regional and local transportation agencies, toll
authorities, and related organizations, including public safety, port, transit, and
rail and other transportation organizations along the U.S. coast, with affiliate
members in Canada; it is neither a governmental entity nor an interstate
compact, but it provides an ongoing forum for interstate collaboration on
transportation and commerce.
Geographically, the I-95 Corridor traverses three traditional U.S. geographic
regions—New England, the Mid-Atlantic, and the Southeast.
The chain of expanding cities and roughly adjacent metropolitan areas
intersecting the Corridor has resulted in three socio-economic ‘megaregions,’
as defined by the Regional Plan Association (RPA), including the Northeast, the
Piedmont Atlantic, and Florida.
3. In terms of overall population density, approximately three times denser than
the U.S. average, the I-95 Corridor is comparable to Western Europe; it also
includes some of the oldest infrastructure in the U.S., and produces high
economic output as a whole.
The common concerns, functional interests, and geographic adjacency of the
state DOTs and other member agencies in the I-95 Corridor Coalition demand
a super-regional transportation systems perspective for improved modal
integration, coordinated policy, planning, and investment decision-making.
Lessons Learned and Challenges
There is a difference between integrating data for display and producing a
useful network. Integration issues included feature resolution, topology,
attributes, and attribute domains. For example, only two or three states had a
roadway centerline database with good network topology. To produce a
Corridor-wide road network that would be useful for network analysis, gaps
and overshoots in the road geometry had to be corrected to yield clean and
correct topological connections, which then needed to be verified and
validated.
Edge-matching across the states was not as big a problem as reconciling the
quality and consistency of the contents of the original datasets, which makes
updates and maintenance very challenging, especially for repeatable
dataset Extraction, Transformation, and Loading (ETL) and conflation, i.e.,
fusion of features and attributes into an integrated dataset.
Geographic conflation, i.e., matching lines, alone is generally not sufficient;
conflation combined with basic roadway identifiers, e.g., road name or route
number, significantly improves the percentage of correct matches.
A methodology is needed for managing road segment IDs (e.g., you can add
new IDs when splitting or adding road segments, and retire the old ones, or
find a way to have persistent IDs (which can be a challenge)).
Most of the state DOTs are only interested in a subset of all roads.
Most of the state DOTs were using FGDC metadata to document their
geospatial datasets.
4. Conclusions
Many variations in data contents and consistency for road datasets were
encountered from state-to-state; but generally, useful and reasonably
accurate road features were available to produce a public domain road
network for the Corridor, for the purposes of the project.
Doing this once is the “easy part” (easy being a relative term); the “hard part”
is doing this on a regular, repeatable basis to keep the road network updated.
If a “do over” was contemplated, it might be easier to use a stripped down
commercial roadway centerline network as a framework, thereby relieving
integration requirements, and improving the consistency and convenience of
updates; the issue would be ensuring public domain accessibility, with no
license restrictions to inhibit use.
A “minimalist view” of needs for TFTN emerged from this project; i.e., you need
the following:
o Good centerline geometry for all roads, including local roads
o Good feature resolution (i.e., travel way representation, not lane level)
o Good positional accuracy (i.e. 1-5m)
o Basic network topology (i.e., road segments connect at at-grade intersections and
freeway ramps, but not at grade-separated overpasses/underpasses.)
o Basic attributes (i.e., road names and numbered routes; addresses and linear
referencing could also be included, or reserved for value-added)
o Regular and predictable updates
