【摘要】：在具有不确定出行时间的交通网络中,假设出行者的参考点是异质的,服从某一连续分布函数,且风险偏好参数是依赖于参考点的,建立了一个基于累积前景理论的多用户网路均衡模型.研究表明,不同类的用户对风险的反应是不一样的,具有高参考点和低参考点的出行者均倾向于选择风险高的路径以期获得较高的感知价值,而具有中等参考点的出行者则倾向于选择风险较低的路径.此外,对两种交通管理措施进行了敏感性分析,结果表明,道路拓宽对于提高整个社会的感知价值是一个有效的方法,但其边际效益是递减的.然而,就风险管理而言,不同类的用户表现出不同的喜好.一般来说,具有低参考点的出行者能够从这一方法中受益,而具有高参考点的出行者则会失去潜在的风险收益.
[Abstract]:In a traffic network with uncertain travel time, it is assumed that the traveler's reference points are heterogeneous, follow a certain continuous distribution function, and the risk preference parameters are dependent on the reference points. A multi-user network equalization model based on cumulative foreground theory is established. The research shows that different types of users react differently to risk, and travelers with high reference points and low reference points tend to choose high risk paths in order to obtain higher perceived value. Travelers with medium reference points tend to choose lower risk paths. In addition, sensitivity analysis of two traffic management measures shows that road widening is an effective method to improve the perceived value of the whole society, but its marginal benefit is decreasing. However, in terms of risk management, different categories of users show different preferences. Generally speaking, travelers with low reference points can benefit from this method, while travelers with high reference points will lose potential risk gains.
