Abstract: The staircases play an important role in high-building evacuation, so it is essential to study the pedestrian dynamics on the stairs. In this paper, we propose an improved heuristic-based model in the single-file staircase movement. In this model, the pedestrian cannot only adjust the desired speed according to the collision distance with the front neighbor, but also choose to stop actively when the front free stairs are not enough. The walking speed decreases with increasing density, and non-propagated stop-and-go occurs at the high density. The simulation results are in agreement with the experimental ones in Chen et al. (2017). Moreover, all the speed, distance headway and free stairs in front decrease as density increases.
