摘要:

出行者路径选择行为的正确性直接影响到交通规划“四阶段”模型最后一步交通分配的可靠性,对交通规划领域具有重要意义.近年来,为了克服出行者路径选择主要理论(随机效用最大化模型)存在的问题,Chorus 提出了随机后悔最小化模型.本文借用经济学领域中的无差异曲线概念,建立基于时间剩余的出行时间和出行费用双重约束下的随机后悔最小化模型,并对模型中存在的路径重叠和路径感知方差问题进行改进.最后运用示例性路网进行数值检验.结果显示,改进模型更加合理,具有更好的可靠性.

Abstract:

The last step of conventional four-stage transport planning model, traffic assignment, is mainly based on the results of modeling the route choice behaviour of travellers. In order to overcome the drawbacks for the majority of travel choice model, random utility-maximization model, Chorus presented an alternative named random regret- minimization model. This paper proposes a dual- constrained random regret model rooted in the economic theory of indifference curve. Considering the case of overlapping and route perception variance, an improved formulation is provided, and the proposed model is tested in sample networks. Numerical results demonstrate the validity of the formulations.

Key words: traffic engineering, route choice, dual- constrained random regret-minimization model, time surplus, indifference curve, overlapping, route perception variance
