摘要
为研究新建地铁开通后配套公交线路的调整,从出行行为角度出发对地铁公交网络进行优化调整.引入前景理论描述有限理性出行者的路线选择行为,假定出行者总是追逐出行收益前景值最大,以此为目标建立路线选择模型.通过测试网络对前景理论和效用理论下的路网平衡态进行分析,结果显示:各路线流量在前景理论下达到平衡态的时间多于在效用理论下达到平衡态的时间,且前者存在较明显的流量振荡;前景值改变阈值对平衡态流量的影响体现了出行者对不确定性的风险抵抗,更贴合实际情况,可依此确定最终的公交线路.
In order to effectively adjust the supporting bus lines after the opening of a new subway line, an optimization of metro and bus network is made from the viewpoint of travel behavior. By introducing the prospect theory to describe the behaviors of bounded rational travelers and by assuming that travelers always chase the maximum value of foreground, a model for route selection is set up. Moreover, the equilibrium state of the road network under the prospect theory and the utility theory is analyzed by testing the network. The results show that the time of equilibrium state under the prospect theory is longer than that under the utility theory, and that the former shows obvious flow oscillation. In addition, the influence of the change threshold of foreground value on the equilibrium flow reflects the risk resistance of travelers to uncertainty, so that it is more suitable for the real situation and more effective in determining the final bus line.
