【摘要】 面对动态交通分配建模需要,针对我国城市交通网络中车辆类型众多,车辆动力性能差异大的情况,基于超车现象的分析,以车辆的类型和自由流行驶速度为划分标准,对路网中的车辆进行了分类,对路段上不同类型车辆的行驶时间函数进行了建模研究,给出了多用户路段行驶时间函数模型。最后用Tsis5.1仿真软件验证了模型的合理性。更多还原

【Abstract】 With analyzing the attributes of mixed traffic in China,multiple user-classes link travel time functions were proposed which could be used in dynamic traffic assignment.The distinction between user-classes was typically based on vehicle characteristics and free flow speed.The asymmetric interaction between the user-classes sharing the same road infrastructure were taken into account.Tsis5.1 was used to testify the efficiency of models.更多还原
