Accelerating solutions for highway safety, renewal, reliability, and capacity AASHTO Design Subcommittee Albuquerque, NM July 17, 2008
2
HALLMARKS Short-term Results-oriented Non-traditional areas Quantum leaps, major advances Inter-related projects Emphasis on openness
3
Safe Highways Better Transport Decisions Reliable Travel Time Great Custome r Service Rapid Renewal and Lasting Facilities FOUR FOCUS AREAS
4
Integrate mobility, economic, environmental, and community needs into the planning and design of new highway capacity $18 million 8 Projects SHRP 2 Capacity Research
5
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
6
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
7
SHRP 2 Safety Research Understanding Driving Behavior $43.2 Million 11 Projects
8
2 Safety Research Tracks Data Collection 2500+ 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
9
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)
10
SHRP 2 Reliability Research reduce congestion through incident reduction, management, response, and mitigation $18 million 12 projects
11
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
12
Traffic Math 101 75 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
13
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
