Query: Simulation of Pedestrian Movements on Slope Using Fine Grid Cellular
  Automata   Cellular automata crowd simulation models have been extensively used to
determine the performance and the safety of crowded structures. In conventional
cellular automata systems, all the cells are of the size of a typical
pedestrian. The free flow speed of a pedestrian is around 1.3m/s, and the
typical size of a cell in conventional CA models is around 45cm. In order to
maintain the upper boundary of movement speed, pedestrians should move 0, 1, 2
or 3 cells at each second in the simulation. These limited number of speed
values pose a limitation on the accuracy of the simulated speed of pedestrians.
Movement speed of pedestrians on a slope depends on the angel of the slope. The
conventional CA limitations do not allow accurate simulation of pedestrian
movements on slopes with different angels. Fine grid cellular automata model
uses much smaller cells (e.g. 5cm or smaller). The model therefore allows much
more possible speed values. In this article, fine grid cellular automata model
is used to model and simulate the movements of pedestrians on a slope. A
walkway scenario is used for the evaluation of the model.
