基于累积前景理论的货运汽车出行路径选择研究

Research on the Route Choice of Freight Truck Based on Cumulative Prospect Theory

高速公路分车型收费政策的实施,对货运汽车驾驶员的出行路径选择有较大的影响。本文结合有限理性理论,将MNL模型中的效用作为累积前景理论的客观效用,将MNL模型中的概率作为累积前景理论的客观概率,以出行路径选择为重点,探索参考点及偏好系数对货运出行路径选择的影响。将调查数据基于MNL—累积前景理论模型进行验证,计算结果表明了模型的有效性。

The implementation of Expressway charging policy by vehicle type has a great impact on the travel path choice of freight vehicle drivers.Combined with the bounded rationality theory,this paper takes the utility in MNL model as the objective utility of cumulative prospect theory,takes the probability in MNL model as the objective probability of cumulative prospect theory,and focuses on travel path selection to explore the impact of reference points and preference coefficients on freight travel path selection.The survey data are verified based on MNL cumulative prospect theory model,and the calculation results show the effectiveness of the model.
