Project Details

Project Description: 

This project aims to produce a software tool that computes surrogate safety measures from vehicle trajectories that were tested with several widely used traffic simulation models and validated with real crash data.

Goals

Safety of traffic facilities is most often measured by counting the number (and severity) of crashes that occur. It is not possible to apply such a measurement technique to traffic facility designs that have not yet been built or deployed in the real world. The purpose of this project is to develop a software tool for deriving surrogate safety measures for traffic facilities from data output by traffic simulation models.
