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 کاملCost-Efficient Querying Strategies for the Crowd
To enhance data processing, crowdsourcing is a mechanism that has evolved recently and has been picked up by companies that refine large amounts of data through so-called crowd workers. Generally, there are two challenges to crowdsourcing: First, the crowd is an uncertain input source because a worker not necessarily knows the right answer or simply answers wrongly. Second, crowdsourcing comes ...
متن کاملA unified structure for crowd simulation
Realistic simulation of crowds is an important issue for the production of virtual worlds for games, entertainment or architectural and urban planning. Difficult issues need to be addressed such as collision avoidance and the handling of dynamic environments. In this paper, we present a unified structure for the simulation of complex urban environments. We propose a topological multiresolution ...
متن کاملDetermining Public Structure Crowd Evacuation Capacity
This paper explores a strategy for determining public space safety. Due to varied purposes and locations, each public space has architecture as well as facilities. A generalized analysis of capacities for public spaces is essential. The method we propose is to examine a public space with a given architecture. We used Bayesian Belief Network to determine the level of safety and identify points o...
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...
