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
