Incorporating Freeway Performance Measures into Real-Time Crash Prediction

PM: Vahid Goftar, P.E.

The main objective of this project is to incorporate freeway performance measures into real-time crash prediction. With predicated crash information, traffic engineers can develop countermeasures that could alleviate crash risk or possibly avoid a crash. To fully automate the process of crash prediction, a standalone computer program tool was developed to predict the risk of crashes for all freeway segments in the Phoenix area in real-time. A performance measurement system was also developed to calculate and store the safety related performance measures, covering mobility, freight, and incident management.
