随着智能交通技术的发展,可变信息标志(VMS)被广泛应用于动态交通管理中。元胞传输模型(CTM)可以很好的模拟交通流激波、排队形成与消散等交通流动力学特性。应用CTM研究了无信息诱导路径选择、基于VMS的近视转换和有界理性路径选择等三种规则,数值模拟结果表明,后两种规则可以减少系统总出行时间,信息服从率越高,系统的改善程度越大。当有界理性规则的“界”参数设置在一定区间内时,该规则优于近视转换规则,否则不如近视转换规则。
With the development of intelligent transportation technology, variable information signage (VMS) is widely used in dynamic traffic management. The cellular transport model (CTM) can simulate the traffic flow dynamics such as traffic flow shock, formation and dissipation of queues. The CTM has been used to study the three rules of no-information-induced path selection, VMS-based myopia conversion and bounded rational path selection. The numerical simulation results show that the latter two rules can reduce the total travel time of the system, the higher the information compliance rate, The greater the degree of improvement. When the bounded rational rules “community ” parameter is set within a certain range, the rule is superior to myopia conversion rules, otherwise not as good as myopia conversion rules.
