A Comparison of Grid-based and Continuous Space Pedestrian Modelling Software: Analysis of Two UK Train Stations

Abstract

The present paper outlines different approaches to pedestrian model- ling, classifying them according to their movement and collision avoidance algo- rithms. An interesting question, not yet fully explored, is whether the simulation output is markedly different between the two main agent-based approaches. The paper explores this question by considering the operational performance of two rail stations in the UK. A software tool with a grid-based approach to pedestrian movement (STEPS 4.0), and a tool with a continuous approach (Legion Studio 2006) have been used to evaluate the gate-line clearance and platform circulation of passengers with respect to proposed station upgrades and future passenger de- mand. The paper concludes by summarizing the advantages of each approach, in the light of the findings from these studies.
