• Abstract:
  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.
