Up to 60% of freeway delays are due to non-recurrent congestion caused by reduced capacity on a freeway section coupled with long incident durations. In such conditions, if proper detour strategies could be implemented in time, traffic could circumvent the congested segments by diverting to parallel arterials. Nevertheless, prior to implementation of any detour strategy, traffic managers need a set of warrants, as detour operations usually demand substantial amount of resources and manpower. This research will develop an effective decision-support tool to assist traffic managers to warrant appropriate detour operations under various incident scenarios and corridor network configurations. Well-justified detour decisions can result in substantial economic savings (e.g. reduced fuel wastage and emissions) and safety benefits for the freight industry and society due to the less delay and fewer stops of trucks and all other vehicles. Such benefits will increase significantly in future with the expected increase in freight traffic on the traffic network. The proposed tool also has the flexibility to be further integrated with other incident management modules to better assist traffic managers in making critical decisions during their daily operations.
