摘要

研究发现，旅行时间可靠性是旅行者选择路线时最重要的考虑因素之一，在旅行者的路线选择行为中起着重要作用。本文建立了基于风险规避的旅行时间可靠性混合模型。为了定义可靠性，我们引入了出行时间预算的概念，将通勤者的风险厌恶与路线选择联系起来。通勤者的出行时间预算根据他们的风险厌恶程度和准时到达的要求而有所不同。设计了出行决策框架，引入了出行需求的模糊层次。我们认为总出行需求由两部分组成，即不常出行者和通勤者。不频繁出行的流量是随机的，它按照固定的路径选择比例随机增加网络流量。我们证明了模型中的约束条件是可行的。

A Model of Travel Time Reliability Based on Risk Aversion

Travel time reliability was found to be one of the most important factors for route choice considerations and plays an important role in travelpsila route choice behavior. This study developed a mixed model to study travel time reliability based on risk aversion. To define the reliability, we introduced the notion of ldquotravel time budgetrdquo to relate commuterspsila risk aversion on route choice. The travel time budget varies among commuters according to their degrees of risk aversion and requirements on punctual arrivals. A framework of travel decision-making process is designed in this paper, and a fuzzy level of travel demand is introduced. We consider that the total travel demand comprises of two parts, the infrequent travelers and commuters. The traffic volume of infrequent travels is stochastic, which adds to the network traffic in a random manner based on fixed route choice proportion. We demonstrated the constraints in the model are feasible.
