Summary
Most, if not all architectural layouts are based on some kind of a grid system. The most common is the regular square grid based on one of three regular tessellations. The other two: triangular and hexagonal are rarely used. Rule-based models for pedestrian dynamics also discretize space in regular grid, traditionally square, but recently also extended to hexagonal grids. This paper compares the influence of different regular grids: square, triangular and hexagonal on the crowd dynamics. The study is based on the classic scenario of evacuation of 200 agents from a square room. The simulations are performed with Crowd-Z at the basic setup: homogenous crowd and constant unitary speed. The results are illustrated with heat maps.
