The Rotated Hexagonal Lattice Model for Pedestrian Flows

Abstract

Various research efforts have been studied on the topic of pedestrian traffic flow. At the beginning of pedestrian research, the modeling and simulation method for the vehicular traffic flow was simply applied to pedestrian traffic flow. Recently, CA based simulation models are frequently applied to pedestrian flow analysis. Initially, the square lattice model (SLM) is a base model for applying to pedestrians of counterflow and then hexagonal lattice model (HLM) improves its network as a hexagonal cell for more realistic movement of the avoidance of pedestrian conflicts. In this paper, the authors suggest the rotated hexagonal lattice model (RHLM) to take the advantages of SLM and HLM for more realistic pedestrian motion. Two simulation models such as SLM and RHLM are compared by the speed, density, and flow. The comparison shows that RHLM can simulate pedestrian flow more realistically from various perspectives.
