Pedestrian simulations in hexagonal cell local field model

• A conception of local field is put forward to direct pedestrian.
• Four moving-preferences and the effect on balance state were discussed in detail.
• The fundamental graphs were used to verify the practicability of this model.
• We proposed a method to detect the press effect near the bottleneck.

Pedestrian dynamics have caused wide concern over the recent years. This paper presents a local field (LF) model based on regular hexagonal cells to simulate pedestrian dynamics in scenarios such as corridors and bottlenecks. In this model, the simulation scenarios are discretized into regular hexagonal cells. The local field is a small region around pedestrian. Each pedestrian will choose his/her target cell according to the situation in his/her local field. Different walking strategies are considered in the simulation in corridor scenario and the fundamental graphs are used to verify this model. Different shapes of exit are also discussed in the bottleneck scenario. The statistics of push effect show that the smooth bottleneck exit may be more safe.
