Influence of Agents Heterogeneity in Cellular Model of Evacuation

TL;DR

This study investigates how different types of heterogeneity among agents, such as velocity, aggressiveness, and sensitivity, affect pedestrian evacuation dynamics using a Floor-Field model, with findings aligning with experimental data.

Contribution

It introduces heterogeneity in multiple agent attributes into a pedestrian evacuation model and evaluates their impact on microscopic flow characteristics.

Findings

Heterogeneity in aggressiveness and sensitivity reproduces microscopic flow aspects.

Velocity heterogeneity appears redundant in modeling evacuation.

Simulation results align with experimental observations.

Abstract

The influence of agents heterogeneity on the microscopic characteristics of pedestrian flow is studied via an evacuation simulation tool based on the Floor-Field model. The heterogeneity is introduced in agents velocity, aggressiveness, and sensitivity to occupation. The simulation results are compared to data gathered during an original experiment. The comparison shows that the heterogeneity in aggressiveness and sensitivity occupation enables to reproduce some microscopic aspects. The heterogeneity in velocity seems to be redundant.
