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

Simulation of pedestrian evacuation with asymmetrical exits layout
TL;DR: A simulation of pedestrian evacuation from a room with asymmetrical exit layout using the improved Dynamic Parameter Model shows that evacuation time depends on the cognition coefficient and imbalance coefficient under normal evacuation condition with reasonable pedestrian and that the pedestrian flow shows distinctive characteristics at different phases.

Long-Range Indoor Navigation with PRM-RL

TL;DR: This article uses probabilistic roadmaps (PRMs) as the sampling-based planner, and AutoRL as the RL method in the indoor navigation context, and shows that PRM-RL with AutoRL is more successful than several baselines, is robust to noise, and can guide robots over hundreds of meters in the face of noise and obstacles in both simulation and on robots.

Unblinking eyes: the ethics of automating surveillance
TL;DR: It is argued that the privacy of the surveilled subject can benefit from automation, while the distance between the Surveilled subject and the CCTV operator introduced by automation can have both positive and negative effects.

A unified multiscale vision of behavioral crowds
TL;DR: A multiscale vision to human crowds is proposed which provides a consistent description at the three possible modeling scales, namely, microscopic, mesoscopic, and macroscopic.

On current crowd management practices and the need for increased situation awareness, prediction, and intervention
TL;DR: In this paper, the authors studied current practices and the role of technology through interviews to crowd managers and found that event planning and monitoring can be complex and sophisticated, but are operated with little support from technology.

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.
