研究和扩展了用于疏散动力学研究的元胞自动机模型--楼层场模型。本文提出了一种计算任意几何形状的房间中的静态地板场的方法，该地板场描述了到出口门的最短距离。为了获得拐角和瓶颈附近的真实行为，还提出了宽出口处的壁面势和收缩效应。这些扩展对于疏散模拟非常重要，特别是在恐慌的情况下。
The floor field model, which is a cellular automaton model for studying evacuation dynamics, is investigated and extended. A method for calculating the static floor field, which describes the shortest distance to an exit door, in an arbitrary geometry of rooms is presented. The wall potential and contraction effect at a wide exit are also proposed in order to obtain realistic behavior near corners and bottlenecks. These extensions are important for evacuation simulations, especially in the case of panics.
