摘要。行人运动仿真模型的应用范围广泛，如建筑疏散、交通工程、大型活动安全管理等。它还为揭示集体行为的潜在机制提供了有效的手段。本文提出了一种改进的启发式模型，该模型在移动过程中明确考虑了潜在的碰撞。同时，在两种典型场景下进行了一系列仿真，验证了关键参数对模型性能的影响。我们发现，当行人在走廊中面对较宽的障碍物时，视觉半径越大，行人越早开始绕行。此外，当行人看到一大群人朝他走来时，他会选择绕行，在人群中以统一的方向移动。此外，该模型可以再现相对高密度情况下的车道形成行人流现象。随着行人视觉半径和潜在碰撞阻力权重的增大，行人车道趋于稳定，逆行行人数量减少。在模型验证方面，仿真结果与已发表的经验数据的密度-速度关系吻合较好。结果表明，改进的启发式模型克服了原模型的不足，能够更真实地再现行人的运动行为。
Abstract. Pedestrian movement simulation models are used for various purposes, such as building evacuation, transportation engineering, safety management of large events. It also provides effective means to uncover underlying mechanisms of collective behaviors. This paper presents a modified heuristics-based model in which potential collisions are explicitly considered during the moving process. Meanwhile, a series of simulations were conducted in two typical scenarios to demonstrate the influence of critical parameters on model performance. We found that when facing a wide obstacle in a corridor, the larger the visual radius, the earlier the pedestrian starts to make a detour. In addition, when a pedestrian observes a large crowd walking towards him, he chooses to make a detour and move in the flow in a uniform direction. Furthermore, the model can reproduce lane formation pedestrian flow phenomena in relatively high-density situations. With the increase of pedestrian visual radius and the weight of potential collision resistance, more stable pedestrian lanes and less moving-through-the-counterflow pedestrians can be observed. In terms of model validation, the density-speed relationship of simulation results agrees well with that of the published empirical data. Our results demonstrate that the modified heuristics-based model has overcome the deficiency of the original model, which is capable of reproducing more realistic pedestrian movement behavior.
