Investigative Low-Cost Safety Measures at Signalized Intersections

  • Pigman, Jerry (PI)

Grants and Contracts Details


Traffic signals are used to reduce traffic congestion and certain types of traffic crashes. However, in some instances, traffic crashes may not be reduced and some types of crashes may increase. Intersections with traffic signals at both high volume, urban locations and high speed, rural locations have been identified as high crash locations. The potential exists to address these high-crash signalized locations with relatively low-cost countermeasures such as additional signal heads or adding delineation to make the signal heads more visible. The study will identify various types of low-cost safety measures and evaluate their cost and effectiveness. The low costs associated with these measures should increase the opportunity of implementation.
