Traffic Safety

The Safety Impact of Traffic Control Intervention at Work Zones

The combination of work zones and passing traffic can be hazardous. Busy environments with moving vehicles and limited space make drivers, pedestrians, and especially workers, all vulnerable. This study tested the introduction of new, highly reflective materials to improve work zone layout visibility for drivers. What resulted were significant reductions in speeds and an improvement in overall speed limit compliance.

Improving Safety of Roads through Speed Management

This research program proposes a comprehensive speed-management solution. The major component of this research program will develop an expert system for selecting optimal speed-management countermeasures and treatments that address specific speeding problems. The system will combine information on driver behaviours, road geometry, and other speed- and safety-related data in a knowledge base to identify potential speed-management countermeasures. In support of this development, the proposed research program will first investigate the effects of road design and roadside environment on speeds and speeding-related accidents. This information will then form the basis of a novel algorithm to predict speed on roads. These components will not only enhance the knowledge base of the expert system, but also address speed management during the design phase.

Anticipated duration: 5 years (April 2013 - March 2020)
