2. TMA Boundary

3. Why required? Why now?
• Transportation Management Area
(TMA) – 200,000 population or
greater
• 2010 Census – KYOVA/Huntington,
WV-KY-OH Urbanized Area
designated as a TMA
• Cabell County, WV
• Wayne County, WV
• Putnam County (portion), WV
• Lawrence County, OH
• Boyd County, KY
• Greenup County, KY

4. Project Purpose
To create a Congestion Management Process that:
• Provides a picture of the state of congestion
• Provides input to development of strategies to
alleviate congestion
• Helps decision makers plan for future system
improvements
• Provides feedback on effectiveness of projects
and strategies
• Provides knowledge base
• Meets Federal requirements

5. CMP Steps
1. Define Regional Objectives
2. Develop CMP Network
3. Develop Performance Measures
4. Collect Data/Monitor System Performance
5. Analyze Congestion Problems and Needs
6. Identify and Assess Strategies
7. Program and Implement Strategies
8. Evaluate Strategy Effectiveness

7. MAP-21: 7 National Goals and Performance Measures
NATIONAL GOALS — It is in the interest of the United States to focus the Federal-aid
highway program on the following national goals:
1. SAFETY— To achieve a significant reduction in traffic fatalities and serious injuries on all
public roads.
2. INFRASTRUCTURE CONDITION — To maintain the highway infrastructure asset system in
a state of good repair.
3. CONGESTION REDUCTION — To achieve a significant reduction in congestion on the
National Highway System.
4. SYSTEM RELIABILITY — To improve the efficiency of the surface transportation system.
5. FREIGHT MOVEMENT AND ECONOMIC VITALITY — To improve the national freight
network … and support regional economic development.
6. ENVIRONMENTAL SUSTAINABILITY — To enhance the performance of the
transportation system while protecting and enhancing the natural environment.
7. REDUCED PROJECT DELIVERY DELAYS — To reduce project costs … delays … and improve
agencies’ work practices.

8. What this means to the KYOVA/Huntington, WV-
KY-OH Urbanized Area
• Public agencies will now have to evaluate
transportation decisions and investments in relation
to these goals and the performance measures/targets
that will be forthcoming
• National Highway System has been redefined by
MAP-21 to include all streets classified as a principal
arterials.

9. What is a Congestion Management Process (CMP)?
• Systematic process that provides
accurate, up-to-date information
on transportation system
performance
• Assesses alternative strategies for
congestion management that
meet state and local needs
• Integrated into the metropolitan
planning process
• Intended to move these
congestion management
strategies into the funding and
implementation stages

10. • Intensity (How bad?)
• Duration (How long?)
• Extent (How far?)
• Variability (How does it
change?)
Four Major Dimensions of Congestion

11. Travel Time Reliability
• Consistency or dependability in travel time
• Drivers less tolerant of unexpected delays because they
have larger consequences than drivers face with
everyday congestion
• Late for work
• Missed appointment
• Late trucking shipment
• Averages don’t tell the full story
Source: Federal Highway Administration

12. Factors That Affect Travel Time
Reliability
• Recurring variations in demand, by hour of day,
day of week, and month of year
• Severe weather
• Incidents
• Work zones
• Special events

13. Travel Time Reliability Measures
• Travel Time Index (TTI)
o Additional time that a trip will take under average congested
conditions when compared to uncongested, free-flowing
conditions
o Ratio of average travel time to free-flow travel time
o TTI = 1.3 means that a trip will take 30 percent longer
• 90th or 95th percentile travel time
o Estimate of how bad delay will be on the heaviest days
• Buffer Time
o Extra time (or time cushion) that travelers must add to their
average travel time when planning trips to ensure on-time arrival
• Planning Time Index (PTI)
o Ratio of 95th percentile travel time to free-flow travel time
o Useful when compared to TTI

16. Recurring
– Demand exceeds capacity
– System choke points
– Predictable  Reliability (Travel Time Index)
Non-recurring
– Incidents
– Work zones
– Weather
– Can be predictable (to an extent)
Two Types of Congestion

17. Role of Congestion Management Objectives
 Define what the region wants to achieve regarding
congestion management
 Serve as primary point of connection between CMP and
Metropolitan Transportation Plan
 Serve as basis for defining direction of CMP and its
performance measures
 Reflect priorities of the MPO
 Serve as tool for MPO to assess how well actions and
policies are helping to achieve goals

18. Questions that CMP Objectives should ask:
1) What do we want to
achieve?
2) What is considered
unacceptable
congestion for the
KYOVA/Huntington
Urbanized Area?

19. Understanding What the Public Wants
• What does the public really care about with
regard to congestion?
• How high of a priority is traffic congestion?
• What type of congestion is most problematic?
For the public? For freight shippers?
• What aspects of congestion are most important
to support livability, safety and economic vitality?

CMP Candidate Objectives

22. CMP Network

• MAP-21 requirements to include National
Highway System
• Typical elements
o Freeways/interstate highways
o Arterial roadways
o Transit service (bus routes)
o Bicycle networks
o Pedestrian networks

23. CMP Network

24. What will the CMP look like at the end?
A defined process that:
– Provides a snapshot of the current state of congestion
– Peak into the future indicating where we can expect congestion to
worsen
– Identification of strategies and projects to mitigate or reduce existing
and/or anticipated congestion
– Prioritization of recommended strategies/projects for implementation
through metropolitan planning process
– Evaluation of effectiveness of previously implemented strategies and
projects
