Primary Project Objectives
This research focuses on ranking bridges for improvements based on winter weather crashes by region. During poor weather conditions bridges freeze before surrounding roadways creating a safety hazard. Utilizing anti-icing methods can prevent or minimize ice from forming on the surface. By prioritizing bridges that are most likely for accidents we can proactively use anti-icing methods to prevent such events from occurring.
The purpose of this research is determining the highest priority bridges during poor weather, in which recommendations are made for anti-icing maintenance operations. By reviewing all winter weather related crashes that occurred on the State Trunk Network over a five year period there is a large sample size to analyze using classifications such as “weather” and “road surface conditions”. Roadway inventory, traffic and crash data were integrated in a GIS framework for this research. With this data certain stretches of roadway can be identified enhancing highway safety.
