Decision Points and Decision Makers
Highlights-Capacity
• Travel Demand Model Partnerships (C10): States/MPOs can partner with bidders
• Workshops on Key Decision Points (C01): need folks from “the trenches”
• Web-based Performance Measures (C02): project finishes in a month
• Case studies on economic impacts of highway expansion (C03): suggestions needed for cases
• Contributions of operations, technology, design (C05): need data sources on arterial flow

Highlights-Safety
• Finalize sample design: driver and vehicles factors (S05)
• Selection of sites for field study (S07)– Urban, rural, suburban– Weather, topography, design factors– Other data sources– Qualified contractors
• Rodeo to test roadside/roadway data collection capabilities (S03/S04)
SHRP 2 Reliability Research
reduce congestion through incident reduction, management,
response, and mitigation
$18 million 12 projects
Reliability
Performance Measures
• Travel Time Variability
• Travel time index: Average travel time/free-flow travel time
• Planning time index: 95th percentile travel time index
• Buffer time: time added to trip to arrive within a window with acceptable probability
• Buffer index: (mean – 95 percentile)/mean
Traffic Math 10175 vs. 90 Minutes Clearance Time:
Explaining the Value of 15 Minutes Saved
• Example:– I-5 northbound, Fife vicinity
– Average 8% trucks
– Two (of four) lanes blocked
– 6:00 a.m., typical Wednesday
– $14 - $18/hour Auto Delay Cost
– $56/hour Truck Delay Cost
• Cost savings of clearing 15 minutes faster = $146,000

Highlights — Reliability
• Project L06 (PB Consult)– Workshop on Institutional Barriers to Non-
Recurring Congestion Management Strategies
• Project L03 (Cambridge Systematics)– Potential Performance Measures and Mitigation
Strategies for Evaluation
• L01 (Midwest Research Institute)– Identification of Case Studies of Successful
Integration of N-RC Operations Business Processes
