MODELLING TRAFFIC INCIDENTS IN URBAN ARTERIAL NETWORKS

This paper introduces a combined traffic simulation-assignment model called SITRAS (Simulation of Intelligent TRAnsport Systems) under development at the Department of Transport Engineering, the University of South Wales. The model provides a tool for the analysis and evaluation of various advanced traffic management systems, such as congestion and incident management systems, public transport priority systems, traffic signal control and dynamic route guidance systems. The paper reports on the first application of the model aimed at quantifying the impacts of incidents in a simple urban arterial grid network. Incidents on one, two and three lanes of a three-lane corridor were simulated for durations ranging from 5 to 60 minutes, and trip and network performance indicators were studied. The results demonstrate the benefits of such a modelling approach in the development of incident management strategies. Future research work will include further enhancements of the model and its application and testing with real urban networks.
