AbstractWe study the modeling of pedestrian dynamics on triangular grids. We consider the cases both with and without orientation. The geometry of a path with orientation may be represented by a special triangular grid with a continuously reducing number of grid cells in the inner side. In addition to the path orientation, a fictional path force will be applied to described the position deviation in this system. In the second case, we consider geometry with no clear orientation. We present here a computation model on the general triangular grid for the step configuration on the local operational level.
