摘要
本文建立了基于参考点的逐日交通流演化模型,模型通过将实际出行时间与参考点进行比较,描述了出行者的感受对估计时间以及路径选择的影响。估计时间模型中用参数取值大小反应出行者对损失的规避大于对等量获得的偏好。分别讨论了出行者乐观、悲观以及中立情况下对应的参考点取值,并研究了三种情况对演化过程及总出行时间的影响。演化结果表明,出行者悲观情况下对应的系统总时间最大,乐观情况下对应的系统总时间最小。该研究有助于理解城市交通流演化的本质规律。
This paper built a day-to-day evolution model based on reference point, which reflected the influence of travelers＂ feelings on the estimated travel time and route choice by comparing real travel time with reference point. In the estimated time model, the different attitudes towards loss and gain that travelers hold were reflected by different value of parameters. Three cases of travelers＂ attitudes, which were optimistic, pessimistic and neutral behaviors, are discussed to analyze the influence on evolution process and total travel time. The evolution results indicated that total travel time was maximum when travelers were pessimistic and total travet time was minimum when travelers were optimistic. This research helps to understand the essential laws of urban traffic flow evolution.
