TLDR
Computer simulations of crowds of interacting pedestrians show that the social force model is capable of describing the self-organization of several observed collective effects of pedestrian behavior very realistically.Abstract:
It is suggested that the motion of pedestrians can be described as if they would be subject to ``social forces.'' These ``forces'' are not directly exerted by the pedestrians' personal environment, but they are a measure for the internal motivations of the individuals to perform certain actions (movements). The corresponding force concept is discussed in more detail and can also be applied to the description of other behaviors. In the presented model of pedestrian behavior several force terms are essential: first, a term describing the acceleration towards the desired velocity of motion; second, terms reflecting that a pedestrian keeps a certain distance from other pedestrians and borders; and third, a term modeling attractive effects. The resulting equations of motion of nonlinearly coupled Langevin equations. Computer simulations of crowds of interacting pedestrians show that the social force model is capable of describing the self-organization of several observed collective effects of pedestrian behavior very realistically.read more

An Agent-Based Microscopic Pedestrian Flow Simulation Model for Pedestrian Traffic Problems
TL;DR: CityFlow, an agent-based microscopic pedestrian flow simulation model, is introduced and it is revealed that the model can approach the density-speed fundamental diagrams and the empirical flow rates at bottlenecks within acceptable system dimensions.

TL;DR: Modelling stride adaptation is important to increase the predictive power of pedestrian models and reformulate the problem as an optimisation problem on a disk around the pedestrian to give visually natural results with an excellent fit to measured experimental data.

Hybrid long-range collision avoidance for crowd simulation
TL;DR: This work proposes a novel algorithm for extending existing collision avoidance algorithms to perform approximate, long-range collision avoidance for distant agent groups to efficiently compute trajectories that are smoother than those obtained with state-of-the-art techniques and at faster rates.

Simulation of evacuation processes in a square with a partition wall using a cellular automaton model for pedestrian dynamics
Xiaoping Zheng,Wei Li,Chao Guan +2 more
TL;DR: A cellular automaton model is presented to simulate the evacuation process in a closed square with partition wall and this model defines a floor field and considers the selection of an exit and effect of social forces.

Improved fluid-dynamic model for vehicular traffic.
TL;DR: The fluid-dynamic traffic model of Kerner and Konh\"auser is extended by an equation for the vehicles' velocity variance, able to describe the observed increase of velocity variance immediately before a traffic jam develops.
