Abstract

This research evaluated a driver-initiated incident detection system that is based on the principle that drivers will report incidents to the responsible highway agency by using in-vehicle communications equipment. A FRESIM model was used to simulate four types of incidents occurring in light, moderate, and congested traffic flow. The results showed that all simulated incident types occurring in light, moderate, or congested traffic were detected quickly with high probability of detection. The performance of the proposed Driver-based Incident Detection System was compared to that of the conventional highway-based Incident Detection System that relies on loop detectors and the California algorithm. The comparison indicated that the Driver-based Incident Detection System was superior as it detected most incidents in a shorter time. This paper also describes the wireless communication technologies that can support the Driver-based Incident Detection System and how the system can be incorporated into evolving Intelligent Transportation Systems.
