针对现有自行车流模型对车辆间作用考虑不足的问题,在原多车道元胞自动机模型的基础上引入动态地场,在模型中纳入了排斥力,并充分考虑了前车速度对后车行驶的影响,体现了自行车的灵活性等特征,提出了换道成本的概念并建立了新的基于比较交通环境的换道规则.数值仿真结果表明:1)该模型能更准确地描述自行车流,反映自行车流的特征,得到的数据符合实际;2)单位车道宽度的通行能力随着车道数的增加有小幅下降;3)激进的驾驶风格使得换道次数大幅增加,通行能力下降.
Aiming at the problem that the existing bicycle flow model does not consider the interaction between vehicles, a dynamic field is introduced based on the original multi-lane cellular automaton model, and the repulsive force is incorporated into the model. , This paper presents the concept of lane changing cost and establishes a new lane changing rule based on comparative traffic environment.The numerical results show that: 1) The model can describe bicycle flow more accurately, Reflect the characteristics of the bicycle flow, the data obtained is in line with the actual; 2) the capacity of the lane width of a unit decreases slightly with the increase of the number of lanes; 3) radical driving style makes the number of lane change significantly increased, the ability to pass down.
