Abstract

In 2008, Wisconsin’s freight transportation system shipped more than $300 billion in goods and the projected volume by 2028 will be another 70 percent increase. Along with the strong demand of truck traffic is the increasing concern of truck-related safety issues. According to the Federal Motor Carrier Safety Administration (FMCSA), 12 percent (4,808) people killed and another 101,000 people were injured in crashes that involved a large truck. Compared to extensive studies conducted on freeway truck crashes, the research on arterial streets is considerably disproportionate given the fact that more fatal crashes involved with large trucks occurred on arterials. Connecting between truck traffic generators, arterial streets are key links to door- to-door deliveries. There is an urgent need to study truck safety on arterial streets because truck related crashes are expected to be reduced through the careful planning of the location, design, and operation of driveways, median openings, street connections, and street sections.

The project will collect extensive data on selected arterial corridors that are heavily used by trucks, identify the crash determinants and develop a risk-based index for these arterial corridors with the emphasis on access management, geometric design, and traffic control. The findings from the study will not only directly benefit state and local agencies in planning, design, and manage a safer truck arterial corridor, but also help carriers to optimize their routes from the safety perspective.

Objectives

  1. Identify truck preferred arterial corridors.
  2. Prototype innovative data collection method to enhance safety asset management for trucks.
  3. Identify heavy vehicle involved crash causal factors.
  4. Examine and review currently available cutting-edge access management methodologies.
  5. Develop an arterial corridor safety risk-based index.

Tasks

  1. Literature review
  2. Truck arterial corridors identification
  3. Extensive data collection
  4. Safety evaluation for selected truck corridors
  5. Corridor safety risk index development
  6. Final report
