摘　　要：震后如何确定有效的救灾路径是救灾管理部门的一项核心工作。本文综合考虑灾区路网受损以及为避免交通拥挤而实施交通管制情况,进行震后救灾路径选择,以提高救援成效,并尽量减少对非灾民的影响。为此,建立了用户均衡交通量指派条件下以救灾路径旅行时间最短和因交通管制引起的扰民程度最小为目标的多目标救灾路径选择模型,并设计了一种两阶段启发式算例进行求解。最后以Sioux Falls路网为例对模型和算法进行验证,并与NSGA-II算法进行了比较,结果表明:该算法在求解效率上与其他启发式算法相比具有显著的优势。A massive earthquake may have serious impact on road networks in the affected area.On one hand,transportation networks have to manage traffic flows arisen from disaster relief and transportation of supplies.Due to time constraint,traffic control measures can result in a change in traffic demand and influence the choice of relief paths.On the other hand,earthquake disasters may cause damage to road systems in the affected area,which would lead to road disruption and the decline of road capacity,,as well as affect the normal functioning of road networks,thus having impact on the choice of relief paths.Therefore,determining adequate post-earthquake relief paths is the core responsibility of disaster management department.This paper considers road networks partially destroyed by earthquake disasters and traffic control measures executed to avoid traffic congestion.The post-earthquake relief routing problem is explored to improve the rescue efficiency and reduce the infiuence of earthquake on non-victims.Firstly,we analyze the characteristics of post-earthquake road networks in the affected area.These characteristics include preearthquake and post-earthquake traffic demand,changes in traffic demand under post-earthquake traffic control,etc.The following assumptions were made：（1） traffic control information is completely open and can be immediately learned by travelers; （2） information about damaged roads can be known in time; （3） traffic demand between each OD pair in pre-earthquake and postearthquake road networks is given ; and （4） according to the actual need,traffic administrative department executes traffic control measures on partial sections of road networks in the affected area,with the exception of relief vehicles.Secondly,a multi-objective optimization model for post-earthquake relief routing problem under traffic control was developed to minimize the travel time and the disturbance of traffic control to non-victims.The travel time of relief path is the sum of traverse time on the selected
