• 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.
