Strategies in crowd and crowd structure
In an emergency situation, imitation of strategies of neighbours can lead to an order-disorder phase transition, where spatial clusters of pedestrians adopt the same strategy. We assume that there are two strategies, cooperating and competitive, which correspond to a smaller or larger desired velocity. The results of our simulations within the Social Force Model indicate that the ordered phase ...
متن کاملCrowd Simulation
I describe an algorithm for simulating crowds in a variety of situations. I formalize the problem as a Markov Decision Process and then apply randomization techniques, along with physically and biologically based methods in order to feasibly solve this problem without discretization. I then evaluate my model with that of simple Boids flocking behavior in order to determine how successful the mo...
متن کاملCrowd - sourced
While many Learning Content Management Systems are available, the collaborative, community-based creation of rich e-learning content is still not sufficiently well supported. Few attempts have been made to apply crowd-sourcing and wiki-approaches for the creation of elearning content. In this article, we showcase SlideWiki -an Open Courseware Authoring platform supporting the crowdsourced creat...
متن کاملCrowd Simulation
Crowd simulations are becoming increasingly important for public authorities and researchers. The film and video game industry have been developing and using tools for crowd simulations for decades. The Maya plugin Miarmy is such a tool, but it was not designed specifically for scientific purposes. We perform experiments in Miarmy to test its functionality. Simple scenes can be set up, simulate...
متن کاملAn Approach for Crowd Density and Crowd Size Estimation
Crowd density estimation is very important in intelligent crowd monitoring. In this paper, a new approach of crowed density estimation is proposed. This method combines the advantage of pixel statistical feature and texture analysis, and reduces the impact of perspective distortion by dividing the region of interest. Moreover, we estimate the crowd size (the range of numbers) for high density a...
