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...

The Intermodal Simulator for the Analysis of Pedestrian Traffic (ISAPT) is being developed for the purpose of modeling pedestrian traffic within intermodal facilities, such that designers may evaluate the impact of building design on the Level of Service provided to pedestrians. The ISAPT system models each pedestrian’s behavior individually and the collective behavior of the crowd is allowed t...

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...

The complexity of vehicle-pedestrian collisions necessitates extensive validation of pedestrian computational models. While body components can be individually simulated, overall validation of human pedestrian models requires full-scale testing with post mortem human surrogates (PMHS). This paper presents the development of a full-scale pedestrian impact test plan and experimental design, and s...

Pedestrian behavioral modeling is a topic that is receiving more and more attention in different areas of application such as panic analysis, building evacuation and surveillance systems. We propose a model based on discrete choice theory for pedestrian dynamic behavior. Our model is based on a local discretization of the space around each pedestrian, as opposed to other models which are contin...

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...
