TMA Boundary
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
Project PurposeTo 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
CMP Steps1. Define Regional Objectives2. Develop CMP Network3. Develop Performance Measures4. Collect Data/Monitor System Performance5. Analyze Congestion Problems and Needs6. Identify and Assess Strategies7. Program and Implement Strategies8. Evaluate Strategy Effectiveness
Topics1 Project Purpose
2 Federal Requirements
3 MAP-21 Requirements
4 CMP Objectives
5 Performance Measures
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.
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.
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
• Intensity (How bad?)• Duration (How long?)• Extent (How far?)• Variability (How does
it change?)
Four Major Dimensions of Congestion
Source: Atlanta Regional Commission
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
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
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 timeo TTI = 1.3 means that a trip will take 30 percent longer
• 90th or 95th percentile travel timeo Estimate of how bad delay will be on the heaviest days
• Buffer Timeo 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 timeo Useful when compared to TTI
Travel Time Reliability Measures (cont.)
Application of Travel Time Reliability Data
Computed using Planning Time Index (PTI)
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
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
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?
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?
KYOVA/Huntington, WV-KY-OH Urbanized AreaCMP Candidate ObjectivesPreserve/Expand Capacity
• I-64 through capacity• I-64 interchanges• Other major regional routes
Enhance System Connectivity
• Ohio River bridges• Connectivity among major
routesImprove Arterial Operations
• Traffic signals/signal systems• Access management

Enhance System Efficiency/Safety
• Incident response• Traveler information• Work zone activity• Transportation Systems
Management• Travel Demand Management• Alternative transportation
modes (bus transit, bicycle, pedestrian)
• Accommodation of freight movement

KYOVA/Huntington, WV-KY-OH Urbanized AreaCMP Candidate Objectives
CMP Network• MPOs have some discretion• MAP-21 requirements to include National
Highway System• Typical elements
o Freeways/interstate highwayso Arterial roadwayso Transit service (bus routes)o Bicycle networkso Pedestrian networks
CMP Network
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 projectsFinal report documenting development and results
