    摘要:

    社会力模型由于模型机制原因,在行人微观仿真时无法实现主动超越行为,现有模型改进研究可通过不同方式实现主动超越,但未关注主动超越完整轨迹的实现和验证。本文以地铁车站通道内中低密度下的单向行人流为研究对象,通过行人步行轨迹分析主动超越行为的轨迹和心理特征。据此通过前进力、换道力、边际力组合构成驱动力,改进社会力模型,实现主动超越,通过速度-密度基本图、超越轨迹及超越行为等对模型有效性进行验证。结果表明,改进社会力模型在实现行人的主动超越行为的基础上,实现了行人返回超越前原始步行道的行为特征,可再现符合实际的行人主动超越轨迹。

    Abstract:

    Social force model is unavailable for active overtaking behaviour in pedestrian microsimulation due to the model mechanism. The active overtaking can be achieved in a variety of approaches of the improved study for existing model. However, the implementation and validation of the complete trajectory of active overtaking shall not be concerned. In this paper, the trajectory and psychological characteristics of active overtaking behaviour by means of pedestrian walking trajectories in a low to medium density one-way pedestrian flow in an underground station channel shall be analysed. Based on this, a combination of forward force, lane change force and marginal force constitutes the driving force to improve the social force model to achieve active overtaking, and the validity of the model is verified through the speed-density basic diagram, overtaking trajectory and overtaking behaviour. The results indicate that the improved social force model can reproduce the actual pedestrian active overtaking trajectory by achieving the behavioural characteristics of the pedestrian returning to the original walking path before overtaking on the basis of the active overtaking behaviour of the pedestrian.
