NATIONAL GOALSGoal Area National Goal
Safety Reduce fatalities & serious injuries on all public roads
Infrastructure condition Maintain a state of good repair
Congestion reduction Significantly reduce congestion on the NHS
System reliability Improve the efficiency of the surface systemFreight movement &
economic vitalityImprove the national freight network, access of rural communities to markets, & economic development
Environmental sustainability Enhance system performance while protecting and enhancing the environment
Reduced project delivery delays
Accelerate project completion by eliminating delays in the project delivery process

STRATEGIC HIGHWAY RESEARCH PROGRAM 2 (SHRP 2) SHRP 2 was created to
Improve highway safety Reduce congestion Improve methods for renewing roads and bridges
KYOVA will use its SHRP 2 grant to establish a process that Conforms to national and state standards Is easily repeatable Coordinates with available data and data gathering practices
STRATEGIC HIGHWAY RESEARCH PROGRAM 2 (SHRP 2)TIMELINE OF EVENTS
January-March 2015 – KYOVA applied for and was awarded funding for C02: Performance Measures for Highway Capacity Decision-Making
May 2015 – Kickoff Conference Call with FHWA and completion of Statement of Work
August 2015 – Notification to proceed with work September-November 2015 – Identify stakeholders and prepare for FHWA
workshop November 2015 – Stakeholder workshop June 2016 – Complete SHRP 2 Implementation Assistance project

STRATEGIC HIGHWAY RESEARCH PROGRAM 2 (SHRP 2) FHWA WORKSHOP
Stakeholders will hear from representatives from FHWA, KYOVA, WVDOT, KYTC, and ODOT about current and forthcoming work on performance measures
Break-out group brainstorming to generate ideas on future “action steps”
Group dialogue on the framework and components of the Action Plan
Discussion of next steps for developing and implementing the Action Plan

2040 METROPOLITAN TRANSPORTATION PLANPRIORITIZATION CRITERIA
Efficiency Reduction in Delay Reduction in Excess Demand Support of Freight Priorities Support of Transit Service Support of Bicycle and
Pedestrian Mobility
Safety Growth Management Economic Development Existing Deficiency Cost Effectiveness State Priority
14
CONGESTION MANAGEMENT PROCESSPERFORMANCE MEASURES
Intensity Volume-to-Capacity Ratio Level of Service Travel Time Index
Duration Extent
Number of Vehicle Miles Traveled at LOS E or F
Total Delay
Variability Crash Rate Planning Time Index
Multimodal Fixed-Route Transit Coverage Bicycle/Pedestrian Routes/Facilities Proportion of CMP Network that
Includes Fixed-Route Transit or Bicycle/Pedestrian Routes/Facilities
15
SPATIAL DECISION SUPPORT SYSTEM (SDSS) A GIS-based system of relational databases, computational tools,
and information sources used to
Store transportation system attribute and performance data
Perform technical analyses that identify/quantify congestion and assess the effectiveness of congestion reduction/mitigation strategies
Provide themes maps and system performance reports for stakeholders and decision makers

CHALLENGES AND OPPORTUNITIES
Providing both consistency and flexibility Finding the right balance of national measures Managing performance across jurisdictions Data requirements and management Linking performance measures to investments Advancing technologies
18
CHALLENGES AND OPPORTUNITIES
Improved communication link between investments and results Increased consistency Increased coordination across jurisdictions Greater understanding of what works Spur discussions on the value of future performance management Improved data collection, integration, reporting, and visualization

A CASE STUDY INHIGHWAY CAPACITY DECISION MAKINGNCDOT PRIORITIZATION PROCESS . BENEFIT/COST CRITERIATRAVEL TIME SAVINGS ANALYSIS . OPPORTUNITY FOR KYOVA
20
NCDOT PRIORITIZATION PROCESS
Strategic Transportation Investments Law passed in 2013
Replaces Equity Formula with Strategic Mobility Formula New data-driven process based on specific criteria Equity Formula would have funded 175 highway projects Mobility Formula will fund 478 highway projects
21
BENEFIT/COST CRITERIA
Highway projects compete in three categories – all include Benefit/Cost criteria Division Needs – 20% Regional Impact – 25% Statewide Mobility – 30%
Benefit/Cost is based on travel time savings
22
TRAVEL TIME SAVINGS ANALYSIS
TransModeler 4.0 is the selected microsimulation software to measure travel time savings for every highway project
Currently analyzing 98 projects – to be completed by end of October
Long-term byproduct is statewide microsimulation model
23
OPPORTUNITY FOR KYOVA
Integrate microsimulation with regional travel demand model
How could microsimulation be used to inform KYOVA’s MTP prioritization process?
Potential performance measures Travel time savings Congestion reduction Queue spillback mitigation
