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.

The variable message signs (VMS) have been widely used in guiding and managing the dynamic traffic with development of intelligent transportation technologies. It is known that the cell transmission model (CTM) can well reproduce such traffic dynamics as shock waves and jams. The CTM is employed in this paper to study the route choice behavior under three different rules, namely the rule without information guidance, the VMS-based myopic switching rule and the VMS-based boundedly rational switching rule.Simulation results show that the latter two rules can enhance the system performance through reducing the total travel time. The enhancement increases with the compliance rate to VMS. The boundedly rational switching rule is better than the myopic switching rule when its bound associated parameter is within a certain range, not so otherwise.
