Perceived cost potential field cellular automata model with an aggregated force field for pedestrian dynamics

Xiao-Xia Jian, S.C. Wong, Peng Zhang, Keechoo Choi, Hong Li, Xiaoning Zhang
2014 Transportation Research Part C: Emerging Technologies  
This paper proposes a perceived potential field and an aggregated force field for the navigation of pedestrians in a walking domain with poor visibility or complex geometries.  ...  While the former field used in uncrowded cells simply reflects the pedestrians' desire to minimize their travel costs, the latter field used in crowded cells suggests much stronger interaction between  ...  Acknowledgements The work described in this paper was jointly supported by the National Natural Science  ...
