Research on the Model of Road Crossing Based on Pedestrian Psychology

The main objective is to conduct analysis of how to make pedestrians safer and more comfortable when they cross the road. A model of road crossing is presented according to subjective consciousness characteristics and psychology of pedestrians. The track of pedestrians crossing the road is the function of such dependent variables as crossing time, average vehicle speed, road width, average density of pedestrians and vehicles, characteristic factor of the road. In addition, the interaction of crossing track, crossing speed, road width and average vehicle speed could be quantitatively evaluated. By this evaluation an integrated index is put forward. This index serves to decide permitted maximum vehicle speed, crossing control scheme and road reconstruction optimization scheme. Ultimately the safety and comfort degree in road crossing are enhanced. In the paper, the reliability of this model is proved by a sample road from Xi'an to Xian yang. The result shows that both road crossing safety and comfort degree change oppositely with overlap of average speed and road width.
