城市交通路段机、非混合运行速度特性分析

近年来,交通问题受到了国内外专家们的重视,提出了各种各样的交通流模型,其中元胞自动机(cellular auotmation,CA)交通流模型的研究受到了广泛的关注.但是通常在元胞自动机模型中并没有考虑非机动车,然而机、非混合路段在我国大量存在.文中提出的机非混合元胞自动机模型模拟了3种车辆(长车、短车、非机动车)在混合路段上的运行,分别对3种车辆在不同密度、混合比例的情况下进行了计算机模拟,最后对运行的数值结果进行分析.该模型能够更加合理的描述机、非混合道路上车辆运行的状况,并且更加符合我国交通流中大量非机动车存在的特点.

Operating Speed of Mixed Traffic Flow of Motorized Vehicle and Non-motorized Vehicle on Urban Road

Researchers of the world pay more and more attention to traffic problem and many traffic models have been put forward.As one of the most attractive traffic models,cellular automation attracts universal attention.However,the existence of non-motorized vehicle,which widely spreads in our country,has not been taken into consideration in the construction of most cellular automation.Three sorts of vehicles,namely,short vehicle,long vehicle,and non-motorized vehicle were simulated based on mixed vehicle cellular ...
