【摘要】：在本文中一种新的力学模型被引入到社会力模型中,用来仿真相向行人流中的跟随行为。这种跟随行为指的是行人通过接近同向行人以避免与反向行人冲突的行为。新的力学模型类似于一种引力模型,在建模过程中考虑了行人的视野范围、自身的运动状态、被跟随行人的运动状态等因素。我们利用新的力学模型对相向行人流进行了仿真,研究了跟随行为对渠化现象、行人间冲突以及双向通道通行效率的影响。仿真结果表明:跟随行为能促进渠化现象形成,并能起到缓解相向行人流拥堵的作用;跟随行为具有降低相向行人流冲突次数的作用,这种作用在入口流量较低时并不明显,但随着行人流量的升高而增强。跟随行为能够提高双向通道的通行效率,并且跟随行为的强度参数越大通道的通行效率越高。
[Abstract]:In this paper, a new mechanical model is introduced into the social force model to simulate the following behavior in the parallel pedestrian flow. This behavior refers to the behavior of pedestrians approaching the same direction to avoid conflict with the reverse pedestrian. The new mechanical model is similar to a gravitational model. In the process of modeling, the range of visual field of pedestrians, their own motion state, the motion state of followed pedestrians and other factors are taken into account in the modeling process. In this paper, we use a new mechanical model to simulate the two-way pedestrian flow, and study the influence of the following behavior on the channelization phenomenon, human conflict and the efficiency of two-way passageways. The simulation results show that the following behavior can promote the formation of the channelization phenomenon and alleviate the traffic congestion, and the following behavior has the effect of reducing the number of conflicts, which is not obvious when the inlet flow rate is low. But with the increase of pedestrian flow. The following behavior can improve the traffic efficiency of the two-way channel, and the greater the intensity parameter of the following behavior, the higher the passage efficiency.
