| 摘 要： | 考虑先进的出行信息系统(ATIS)对出行者路径选择行为的影响,提出了一种混合随机用户均衡交通分配模型。将出行者划分为"有ATIS接收装置"和"无ATIS接收装置"两类,两类出行者均以随机方式选择出行路径,路径选择准则为广义出行负效用最小,广义出行负效用定义为出行时间、出行费用和出行时间可靠性的线性组合。利用混合网络随机用户均衡建模理论,建立了ATIS影响下基于广义出行负效用的随机型分配变分不等式模型,基于二次加权平均方法设计了求解模型的启发式算法。通过一个简单算例验证了文中所构建的模型和算法,并获得了一些重要的结论。

| Abstract: | This paper presents a mixed stochastic user equilibrium traffic assignment model in road networks served by advanced traveler information systems(ATIS).All travelers are divided into two groups,equipped and unequipped with ATIS respectively.A concept of generalized travel disutility is introduced based on three criteria,travel time,travel cost and travel time reliability.It is assumed that travelers in both groups make their route choices in a logit-based stochastic manner,and try to minimize their generali... |
