Abstract

The reliable simulation of pedestrian movement is an essential tool for the security aware design and analysis of buildings and infrastructure. We developed HyDEFS, an event-driven dynamic flow simulation software which is designed to simulate pedestrian movement depending on varying routing decisions of the individual users and varying constraints. HyDEFS uses given density depending velocities to model congestions and evaluates flow distributions with respect to average and maximum travel time. This is of particular importance when considering evacuation scenarios. We apply HyDEFS on two small networks and cross validate its results by time-discrete and time-continuous calculations.

Highlights

Modelling and simulation of pedestrian flows are often applied to the design of traffic infrastructures or the evaluation of rescue routes [1,2,3]
When choosing a route along the shortest path, it is implicitly assumed that all pedestrians have complete knowledge of the possible routes
The simplification is significant when assuming that pedestrians choose the fastest route, since knowledge about the occupancy level would only be given if all routes can be viewed by the pedestrian

Summary

Introduction

Modelling and simulation of pedestrian flows are often applied to the design of traffic infrastructures or the evaluation of rescue routes [1,2,3]. That all pedestrians choose the shortest path [5] or the fastest route [6]. When choosing a route along the shortest path, it is implicitly assumed that all pedestrians have complete knowledge of the possible routes. While in schools and office buildings it can be assumed that the users are familiar with the infrastructure, in subway stations or railway stations, this is not necessarily the case. The simplification is significant when assuming that pedestrians choose the fastest route, since knowledge about the occupancy level would only be given if all routes can be viewed by the pedestrian
