Intersections offer a challenge to transportation agencies because a third of fatal crashes occur at intersections. This is primarily due to drivers not recognizing an acceptable gap thereby resulting in a right-angle crash. Intersection Conflict Warning Systems (ICWS) offer an intermediate cost solution that can be more effective than lower-cost solutions in reducing fatal and severe injury crashes. However, ICWS can present special challenges to local agencies that are considering deployment. These challenges include cost, technical resources to operate/maintain the system, and utility locates of underground components.

This presentation will focus on an actual deployment of a low cost next generation prototype ICWS in St. Louis County, Minnesota. It will include discussion on proactively identifying at-risk intersections, expected safety benefits of ICWS, how to use available information to identify the type of design that best fits a local need, and long-term maintenance considerations. Also included will be an overview of the Minnesota Local Road Research Board’s Cloud-Based Dynamic Warning System. The research project tested and validated a smartphone app that can alert drivers when travel speeds exceed the safe travel speeds on horizontal curves.
