Abstract

Traffic simulation modeling alternatives are briefly discussed, and the chosen traffic model and the study areas to which it was applied are described. The effects of driver information and incident duration, severity, and location are quantified and discussed, and recommendations are made for future work. The ability of a user equilibrum-based traffic simulation model to simulate the traffic-related impacts of urban freeway incidents is demonstrated. The paper also shows important relationships between driver information, incident duration, incident location, and overall system performance, as measured in terms of vehicle hours and average commute time. The study findings show that incident-impacted roadways need to be rapidly restored to full capacity because the cost of urban incidents can easily exceed $2,000 per minute of incident duration.
