摘要
为了更加真实的反应驾驶者在出行选择过程中的行为、以及出行结束后产生的后悔与欣喜对未来出行选择倾向的影响,借助后悔理论建立了包含预期属性效用、选项自身预期后悔与相对预期后悔的效用函数,并依据Logit选择模型建立了出行选择混合效用选择概率模型。为了说明模型各部分对混合效用的影响,使用Matlab模拟的方法对模型中的参数进行了分析。根据算例得出的结果,认为驾驶者的路径选择与感知的路径属性值的可靠性、后悔规避系数、风险规避系数有关。
In order to more realistically describe driver＇s behaviors in the process of travel choice and the impact of regret/rejoicing which brought about at the end of travel on the travel tendency in the future,a hybrid utility function including anticipated properties utility,self anticipate regret and relative was established by using the theory of regret,and a hybrid utility probability model for route choice was presented based on Logit model.For explain the effect of the different parts of the model on the hybrid utility,the parameters in the model were analyzed using Matlab simulation.Based on the result of the illustration,it is believed that driver＇s route choice is related to the reliability of the properties of the perceptive routes,coefficient of regret avoidance and coefficient of risk avoidance.
