Abstract — Traffic incidents are any non-recurring event including traffic crashes, disabled vehicles, roadway maintenance and reconstruction projects, and special non-emergency events, e.g., ball games, concerts, or any other events that significantly affect roadway operations. They can cause a significant capacity reduction of roadway. Our work is to design traffic incident management strategies to reduce road traffic congestion caused by incidents. Advanced information and communication technologies can be used to facilitate this work. A Dijkstra’s algorithm is used to generate a subnetwork where vehicles receive the incident information and detour. We also design new traffic signal strategies at signalized traffic intersections. It needs two kind of additional traffic signal lights named ban and warning ones. The ban light helps to stop the traffic flow driving towards some directions while the warning one is used to give traffic flow a recommendation of not driving to some directions. Timed Petri nets (TPNs) are utilized to describe the cooperation between traffic lights and warning lights, and then verify their correctness. The effectiveness of these strategies are evaluated through simulations in the grid traffic network modeled via cell transmission model. The results reveal the influences of some major parameters such as the ratio of route-changing vehicles over the total ones, operation time interval of the proposed strategy, and traffic density of the traffic network on an incident-induced congestion dissipation process.
