The present study was designed to assess the efficacy of the driver- initiated incident detection system by evaluating how new communications technologies can mitigate problems that beset current cellular call-in programs - such as insufficient information on incident location, false reporting, and duplicate calls. An analytical model supported by field data for several important variables was used to determine the system performance measures, which were the detection rate, mean time-to-detect, and false alarm rate. The results indicate that when the new geolocation and digital technologies that lead to the automatic detection of the location of the driver initiating an incident call are implemented, the driver- initiated detection system is effective. The system achieved good detection rates and faster detection times across all simulated incidents occurring under variable traffic flow rates that ranged from light traffic to congested traffic
