Developing a Collision Warning and Collision Avoidance System for WYDOT Snowplows

The main goal of this study is to develop a collision warning and collision avoidance system for Wyoming Department of Transportation (WYDOT) snowplow trucks and other maintenance vehicles, to maximize the capability of preventing crashes, and to minimize the severity of crashes. In support of this broader goals, the study is aimed to fulfill the following objectives: (1) Develop a rear-end collision warning and collision avoidance system using multiple sensors based on the outcomes from an extensive safety analysis, simulation models, and the responses from surveys. (2) Evaluate the performance of color and type of warning lights in reducing crashes involving snowplows and other maintenance vehicles. (3) Test the performance and effectiveness of a prototype using WYDOT’s winter maintenance truck equipped with the technology and proposed warning lights. (4) Perform a benefit-cost analysis of the proposed collision warning and collision avoidance system before the full-blown implementation of the final products. (5) Develop a guideline on how the subset of multiple sensors with warning lights from the proposed warning system can be transferred and employed in other slow-moving WYDOT maintenance vehicles to reduce the potential risk of rear-end collisions.
