Performance Measure Challenges
• Some measures only applicable to certain scales• How do we establish outputs vs outcomes?• Many measures come from models and not real world
observations (many assumptions)• Conflicting or contradictory goals• Correlation does not mean causation• Redundancy in measures based on common initial variable

Regional Travel Demand
2010 Travel Sheds from CBD by Time of Day
Scenario Quadrilaterals
Potential Walking Demand Measure
• 10 minute walking sheds• “Potential demand” for
short walking trips– Proximity to retail/service– Street Network– Number of households
• Desired to match demand with infrastructure improvement
Potential Walking Demand Measure
Retail & Service Employment * Households * Intersections
Retail & Service Employment + Households + Intersections

Multimodal Accessibility Measure
• Looked at travel times to employment by different modes using the travel demand model– 30 minutes by car– 15 minutes by foot– 45 minutes by transit
• Areas with the ability to reach employment by multiple modes score better

Congestion Ranking – Intensity
• Measures peak daily expected congestion
• Maximum value from AM/PM weighted TTI
24
Congestion Ranking – Duration
• Measures how much time of the day a facility is congested
• Weighted V/C ratio by time and distance
25
Congestion Ranking – Extent
• Measures the number of people impacted
• Total facility vehicle hours of delay
26
Congestion Ranking – Most Congested

Needs Assessment Conclusions
• Intercounty travel demand is expected to increase
• Rail travel offers good reliability
• Sprawling development hinders mode choice
• Measures serve as a tool for future project evaluation
• Increasing walkability and mode options helps:– Reduce emissions– Improve public health– Improve transportation equity
