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

A social force evacuation model driven by video data
TL;DR: The initialization of pedestrian position, path navigation, and goal selection in the improved social force model was guided by real video data, and a new force called “group force” was added to the primarysocial force model.

An Efficient Method of Crowd Aggregation Computation in Public Areas
TL;DR: A novel global feature is used to represent the moving crowd and a strategy is adopted to cluster the feature points first and then calculate the collectiveness, which makes the Collectiveness computation of individual groups more consistent and effective.

Route choice in pedestrian evacuation: formulated using a potential field
Ren-Yong Guo,Hai-Jun Huang +1 more
TL;DR: Simulation results indicate that the proposed method can simulate two classes of phenomena that cannot be reproduced accurately by existing methods, and illustrate that, for improving the efficiency of evacuation, excessive or limited sensitivity of pedestrians to the route capacity may be unhelpful, and adding an extra route may be inefficient.

A pedestrian flow model considering the impact of local density: Voronoi diagram based heuristics approach
TL;DR: Wang et al. as discussed by the authors introduced the Voronoi diagram into the heuristics based pedestrian flow model, which provides not only local density but also other information for determining moving velocity and direction.

Kinetic theory of vehicular traffic
TL;DR: A theory of multi-LANE traffic flow and the space-time evolution of thevelocity distribution of cars are examined to help understand the role of driver behaviour and strategy in this network.

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.
