Abstract:

From the perspective of pedestrian visual cognition, a pedestrian-vehicle micro-interaction model based on the atten-tion field of pedestrian vision is proposed. The attention field of pedestrian vision is constructed to drive the pedes-trian field of vision, and the artificial potential field is used to drive the pedestrian movement,. The target capture algorithm is used to control the target capture in the pedestrian visual field. In order to verify the effectiveness of the model, drones are used to collect the pedestrian-vehicle interaction data from the bird's-eye perspective and analyze them. Pedestrian crossing styles are divided into three types: conservative, cautious and adventurous. Simulation scenarios and interactive models are built on the Pygame platform, then, different types of interactive data are used as the model input, the similarity between the pedestrian spatiotemporal trajectory output by the model and the collected real spatiotemporal trajectory is experimentally compared. The results show that the pedestrian-vehicle mi-cro-interaction model based on pedestrian visual attention field is 25.48% more accurate than the conventional artifi-cial potential field model, and it can effectively reproduce the pedestrian-vehicle interaction process in the actual traf-fic scene.

Key words: pedestrian-vehicle interaction, pedestrian crossing style, pedestrian attention field of vision, artificial potential field
