针对能见度较低或几何形状复杂的步行区域，提出了感知势场和聚合力场的概念。前者用于不拥挤的车厢只是反映了行人将出行成本降至最低的愿望，而后者则用于拥挤的车厢，表明行人之间的互动要强得多。与不考虑后一场的模型相比，该模型在模拟拥堵的行人流方面具有优势，例如在瓶颈的前面或在走廊中的左/右转弯处；所模拟的现象，包括相变和基本原理图，与文献中的观察和研究相一致。(C)2014爱思唯尔有限公司。保留所有权利。
This paper proposes a perceived potential field and an aggregated force field for navigation of pedestrians in a walking domain with poor visibility or complex geometries. While the former field used in uncrowded cells simply reflects the pedestrians' desire to minimize their travel costs, the latter field used in crowded cells suggests much stronger interaction between pedestrians. Compared with a formulation that does not include the latter field, the proposed model displays an advantage in simulating over-crowded pedestrian flows, e.g., at the front of a bottleneck or at a left/right turn in a corridor; the simulated phenomena, including phase transitions and fundamental diagrams, agree well with the observation and studies in the literature.
