The objectives of this project were to assist NCDOT's Traffic Safety Systems Management Unit in incorporating two scientific advances into its programs.
These advances are:
- A methodology for periodically evaluating the effectiveness of implemented safety countermeasures
- The capability to identify sites with abnormally high crash rates and patterns using existing crash prediction models.
In particular, the project team recommended software that will allow the TSSMU to regularly perform statistically valid evaluations of countermeasures that the NCDOT is installing, and the team wrote software to execute crash prediction models to judge the relative hazardousness of different highway sites.
