| 摘 要： | 为了便于研究城市交叉口混合交通信号控制策略以及城市信号交叉口交通仿真,对信号交叉口人行横道绿灯放行时间内行人自行车聚集群的交通特性进行了研究.在此基础上,提出了行人自行车"聚集群"的概念,运用了把人行横道"虚拟网格化"的方法对行人自行车聚集群的形状、面积、空间位置以及空间占有率等参数进行了描述.以北京市平乐园信号交叉口为例,对聚集群的空间占有率变化进行了计算.结果表明,聚集群的空间占有率在行进过程中是逐渐增加的.

| Abstract: | The research embodied in this paper presents the characteristics of pedestrians and bicycles conglomeration of the green time on the crosswalks,so as to study the signal control strategy and the traffic simulation of the signalized intersection.Firstly,a new definition of the pedestrians and bicycles conglomeration is presented under analyzing the releasing characteristic in the signalized intersection crosswalks of green time.Then,a new method is used which is that the crosswalk is divided for many uniform... |
