摘要

摘要: 为有效解决应急疏散路线中存在的延误问题, 以总体疏散费用最小为目标, 以消除冲突点, 减少交织点, 并且以流量守恒、流量非负、节点和弧段的通行能力限制等为约束条件, 提出了基于车道层面的路网模型。利用Lingo软件, 分别对应用基于车道层面的疏散扩展网络流模型以及应用基于路段层面的节点-弧网络模型进行求解, 并以4个交叉口网络为例进行了对比分析。计算结果表明: 与应用基于路段层面的节点-弧网络模型相比, 应用基于车道层面的扩展网络流模型节约了4 h·veh^-1的出行费用, 出行成本降低了25%, 该模型在使疏散费用最小化的同时, 减少了交织情况产生的延误, 具有较高的疏散效率。

Abstract: In order to effectively solve the potential delay during emergency evacuation routes, a lane-based network flow model was presented, its objective was the minimum of whole evacuation cost, and its constraint conditions were eliminating crossing-conflicts, reducing confluence, flow conservation and non-negative, restricting the traffic capacities of nodes and arcs. The expansion network flow model based on lane level and the traditional node-arc network model based on road level were solved by adopting Lingo software respectively, and a network including four intersections was analyzed as an example. Analysis result indicates that compared to the traditional network model, the travel cost saves four hours per vehicle, and reduces by 25% through the lane-based extension network flow model, so the model can minimize evacuation cost, reduce delay caused by merging and crossing, and improve evacuation efficiency.
