Аннотация: In this paper a connection of a width of a bottleneck and unidirectional virtual people flow by the SIgMA.CA pedestrian movement model (stochastic Cellular Automata model) is investigated. Specific and full flow rates for different model parameters, initial densities, and bottleneck width are presented and discussed. В© 2012 Springer-Verlag Berlin Heidelberg.

Аннотация: This article is focused on dynamics of the computer simulation module SigmaEva in bottlenecks. Unidirectional flow was considered. The module SigmaEva realizes the discrete-continuous stochastic pedestrian dynamics model SIgMA.DC that is shortly presented here. Specific and full flow rates for different bottleneck width are given in comparison with experimental data. (C) 2014 Elsevier B.V. All rights reserved.

Аннотация: In the paper the semi-Lagrangian method is considered in the context of its implementation with the CUDA technology. We have scrutinized the bottleneck of our sequential algorithm; its parallel versions are studied in detail; and the main reason of poor CUDA performance is clarified. As the result, we revise the computation of partial integrals in order to improve the efficiency of the algorithm. Numerical experiments demonstrate good CUDA performance of the revised version of the algorithm.

Аннотация: A connection of a width of a bottleneck and unidirectional virtual people flow by the discrete-continuous pedestrian movement model (Kirik et al. Fundamental diagram as a model input direct movement equation of pedestrian dynamics. In: Proceedings of the international conference pedestrian and evacuation dynamics '2012, Zurich. Springer, 2014) is investigated. Specific and full flow rates versus bottleneck width are presented. Computational artifacts that are pronounced while simulation in front of bottleneck are discussed.
