Modeling of evacuation and background traffic for optimal zone-based vehicle evacuation strategy

摘要: This paper discusses details of developing an optimal zone-based vehicle evacuation strategy based on optimization-simulation approach. The egress is obtained by solving a universal quickest flow problem, and the solution implemented evaluated in mesoscopic simulation model. Evacuees would follow routes to safe locations outside hot zone then select behaviorally realistic their final destinations. Background traffic included model simulate more conditions. route choice background response driver information strategies carefully addressed. Operational issues such as temporal loading intensity queuing at parking lots are also modeled discussed. modeling framework has been applied bomb threat scenario football stadium. case study shows that proposed methods generate reasonable meaningful results for intended no-notice scenario.
