9. 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

14. CONGESTION MANAGEMENT PROCESS
PERFORMANCE 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

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

16. SPATIAL DECISION SUPPORT SYSTEM (SDSS)
Map Figures
KYOVA Transportation Management Area Boundary Volumes from Traffic Model Assignments
CMP Network Capacities from Traffic Model Assignments
Major River Crossings V/C Ratios from Traffic Model Assignments
Fixed Route Transit Coverage Levels of Service

17. 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
17
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

19. A CASE STUDY IN
HIGHWAY CAPACITY DECISION MAKING
NCDOT PRIORITIZATION PROCESS . BENEFIT/COST CRITERIA
TRAVEL TIME SAVINGS ANALYSIS . OPPORTUNITY FOR KYOVA
19
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
20
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
21
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
22
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
