Accelerating solutions for highway safety, renewal, reliability, and capacity AASHTO Design Subcommittee Albuquerque, NM July 17, 2008

HALLMARKS Short-term Results-oriented Non-traditional areas Quantum leaps, major advances Inter-related projects Emphasis on openness

Safe Highways Better Transport Decisions Reliable Travel Time Great Custome r Service Rapid Renewal and Lasting Facilities FOUR FOCUS AREAS

Integrate mobility, economic, environmental, and community needs into the planning and design of new highway capacity $18 million 8 Projects SHRP 2 Capacity Research

Long-Range Corridor Environmental Design Permitting Planning Planning Review Effects of Congestion Pricing Models and Assignments Performance Measures Habitats & Wetlands Planning and NEPA Economic Impact and Land Use Effects of Technology Effects of Road Management FHWA DOTs MPOs Resource Agencies Citizens Elected Officials Advocacy 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

SHRP 2 Safety Research Understanding Driving Behavior $43.2 Million 11 Projects

2 Safety Research Tracks Data Collection Drivers Data Collection Vehicles at Intersections Countermeasures Data Analysis Crash Risk In-Vehicle Study Site-Based Study Data Analysis Traffic Roadway Conditions Traffic Controls Weather Distractions

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: 95 th 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 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 Source: WSDOT

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
