Abstract

Planning pedestrian environments requires that designers understand how pedestrians interact with their environment and one another. With improved knowledge, the design and planning of pedestrian areas can provide improvements in safety, throughput, and utility. This paper provides an overview of the Intermodal Simulator for the Analysis of Pedestrian Traffic (ISAPT). It focuses on the methodologies used in simulation of the pedestrian traffic, including route planning and navigation. Several illustrations of the system’s ability to reproduce observed crowd behavior are provided.

2. Isapt System

Broadly speaking, ISAPT is designed to simulate pedestrian traffic within a facility taking into account the diversity one might find in such a facility in terms of pedestrian characteristics, along with their specific trip plans. The system can generate variable pedestrian populations exhibiting specific traits at multiple entry points within that facility. Each pedestrian enters the system with a set of objectives in mind (e.g., reach departure gate by 1:30 pm) and a tentative plan (agenda) to meet them being provided with the means to utilize one or more of multiple resources located throughout the facility (e.g., ticketing, restaurants, restrooms, etc.). While in transit a pedestrian is able to dynamically re-plan, altering their route based on the environmental conditions that exist (e.g., long queues at the restaurant). When the pedestrian reaches their final departure point they may proceed to exit the system. As pedestrians move about the facility carrying out their agendas, individual statistics are collected with respect to their utilization of resources and the paths they follow.
