Abstract:

In view of that pedestrian?vehicle collisions often happen in the process of pedestrians’ street crossing, a street?crossing intention recognition network MIFRN is proposed based on pedestrians’ action prediction and environment contexts in this paper. MIFRN encodes pedestrians’ future actions information, local traffic scenes surrounding pedestrians, vehicle speeds, and pedestrian?vehicle distance information respectively through structure?varying sub?networks, and predicts pedestrians’ intention of street crossing on the basis of information fusion. Finally, the performance of algorithm is verified based on two public databases PIE and JAAD. The results indicate that the method proposed can recognize pedestrians’ street?crossing intentions accurately and robustly.

Key words: intelligent and connected vehicles, pedestrian crossing intention, action prediction, environment context
