A Microscopic Simulation Model for Incident Modeling in Urban Networks

<title>A<sc>bstract</sc> </title> This paper reviews the main modules of an integrated system for incident management in real-time, <inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="gtpt_a_239697_o_ilf0001.gif"/>-sim. A core to such a system is a microscopic simulator with extended abilities to model the temporal and spatial evolution of specified non-recurrent traffic conditions. The paper reviews the mathematical formulation of the car-following and lane-changing modules. The model is validated using a simulation-based approach. Concluding comments on the general validation process of the model are provided. The paper finally presents a sample of the accident patterns replicated by the model together with their implications for real world validation.
