Abstract:

To improve traffic conditions on major highways plagued by non-recurrent congestion, most

highway agencies have invested their resources in two principal operational programs: incident response

and clearance, and traffic impact management. However, even with the wide-spread implementation of

such programs, effectively minimizing the traffic impact caused by multi-lane blocked incidents remains a

critical and challenging issue for most highway agencies. This research developed a multi-criteria

decision-support system for determining the necessity of detour operations during incident management

from an overall socio-economic benefit perspective. The developed system enables responsible agencies

to consider all associated critical factors with preferred weights, including the direct benefits and

operational costs, safety and reliability, accessibility of detour, and acceptability by travelers. This

research is part of our developed integrated incident managing system for SHA that has various essential

functions, ranging from prediction of incident duration to estimation of operational benefits. This decision

module, based on the AHP (analytical hierarchical process) methodology, features its computing

efficiency and operational flexibility, allowing users to make necessary revisions if more data are

available or more criteria need to be included.
