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
Needs Assessment Performance Measures Travel Demand Model Output Composite Analysis Measures
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
Potential Walking Demand Measure Cumberland Perimeter Center Lindbergh Buckhead Midtown Decatur Downtown VAHighlands
Potential Walking Demand Measure Transit Stations LCI Areas
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
Multimodal Accessibility Measure Envision 6 2040
Multimodal Accessibility Measure Concept 3 2040
Congestion Ranking – Intensity • Measures peak daily expected congestion • Maximum value from AM/PM weighted TTI
Congestion Ranking – Duration • Measures how much time of the day a facility is congested • Weighted V/C ratio by time and distance
Congestion Ranking – Extent • Measures the number of people impacted • Total facility vehicle hours of delay
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
