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.
