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

The present paper outlines different approaches to pedestrian modelling, classifying them according to their movement and collision avoidance algorithms. 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 demand. The paper concludes by summarizing the advantages of each approach, in the light of the findings from these studies.
