Project Overview

Rapid growth in the volume of public transport and the need for its reasonable, efficient planning has made the description and modeling of transport and pedestrian behaviors an important research topic in the last twenty years. In the study of pedestrian behavior, evacuation scenarios (in which pedestrians all target a definite destination) and multi-agent systems (in which pedestrians are treated as heterogeneous individuals) have attracted much attention as two specific problems.

Comparatively little attention has been paid to the problem of pedestrian crowd behaviors in geometries with multiple destinations: each of the possibly many pedestrians moves to one out of a number of destinations. The objective of the present study is to investigate pedestrian behavior in such a context. The central problem is the modeling of intersecting pedestrian flows. In view of a desirable practical relevance, realistic, i.e., rather complex geometries are studied in this context.

Simulation models

In the last years, several methodical approaches have been investigated for the modeling and the simulation of traffic problems. In the present context, it seems adequate to develop both microscopic approaches in which the pedestrian is considered as an individual interacting with other pedestrians, and macroscopic models in which pedestrian behavior is analyzed in terms of more global properties of a continuous stream.

  • Macroscopic/mesoscopic models [2]



Evaluation and Experiments

Beyond the modeling of the above-mentioned problems, a particular aim of this project is the development, implementation and test of appropriate computer-based simulation models. The reliability of these models will be illustrated by a comparison with real data obtained from intersecting pedestrian flows experiments.

We have carried out several experiments to gather data for analysis and evaluation. One particular series of experiments was conducted, for example, during the Lange Nacht der Wissenschaften 2010.

Typical applications of these approaches include real-world scenarios like airports, shopping malls, buildings of middle to large size etc., where the participants (i.e., the pedestrians) do not exhibit an overall unanimity and (may) have different and multiple destinations
