The calibration and validation of pedestrian simulations require the acquisition of empirical evidences of human behaviour. The current work presents the results of an experiment focused on the potentially combined effect of counter flow and grouping on pedestrian dynamics. In particular, we focused on: (i) four different configurations of flow ratio (the rate between the minor flow and the tot...

This paper presents an analysis of pedestrian traffic performance from an empirical study. Video footage from a university building corridor was used to quantify pedestrian behavior for inclusion in a pedestrian simulation model. A coordinate conversion technique that maps images in the footage onto a real-world coordinate system was used for data collection. Pedestrian characteristics such as ...

Some simulation environments may wish to evaluate effects on flow and movement, such as in a pedestrian simulation. Analysis of the flow is particularly useful when the map in which the flow occurs is modeled as a node-edge graph. I create a simple pedestrian simulation in which pedestrian movement occurs in a node-edge graph and the pedestrians direct themselves towards an “escape” node as the...

5 This study establishes a mathematical model that can represent the conflicting effects of two 6 pedestrian streams with an oblique intersecting angle in a large crowd. In a previous study, a 7 controlled experiment in which two streams of pedestrians were asked to walk in designated 8 directions was used to model the bi-directional pedestrian stream of certain intersecting angles. In this 9 s...

EvacSim is a multi-agent building evacuation simulation featuring pedestrian occupant agents occupying twodimensional continuous free-space to simulate pedestrian egress for building evaluation and evacuation planning support. We detail pedestrian model elements that govern microscopic agent movement such as personal space preservation, obstacle avoidance and moving together as a crowd. We vali...

Abstract – An understanding of how to alter crowd dynamics would have a significant impact in a number of scenarios, e.g., during riots or evacuations. The social force model, where individuals are self-driven particles interacting through social and physic...

Pedestrian overflow causes queuing delay and in turn, is controlled by the capacity of a facility. Flow control or blocking control takes action to avoid queues from building up to extreme values. Thus, in this paper, the problem of pedestrian flow control in open outdoor walking facilities in equilibrium condition is investigated using M/M/c/K queuing models. State dependent service rate based...

Due to the poor transfer organization in urban public transport terminal, pedestrian crowd are often forced to weaving in their transfer flow lines. Frequent weaving behaviors not only decrease passengers’ transfer comfort, but may also trigger serious crowd disaster such as trampling. In order to get accurate understanding of the weaving features of pedestrian crowd and analyze the relevant ev...
