Abstract:

In view of the current problem that pedestrians are vulnerable to vehicle impact and lack of active protection means, an intelligent wearable device including radar module to protect pedestrians from vehicle impact is proposed in this study. On this basis, a safety intelligent algorithm based on fuzzy comprehensive evaluation is proposed. From the perspective of pedestrians, radar-detected vehicle data, local road traffic conditions, weather, pedestrian status and other factors are considered as evaluation indicators. In order to improve the accuracy and adaptability of the algorithm, a method based on BP neural network and multi-agent reinforcement learning is proposed to give dynamic weights to each index of fuzzy comprehensive evaluation. The simulation results shows that the alarm accuracy of the algorithm is more than 55% higher than that of the weighted method such as AHP, and the learning efficiency of the algorithm is nearly 28 times higher than that of the single agent reinforcement learning, which indicated that intelligent wearing equipment can effectively predict and warn the impact of vehicles on pedestrians.

Key words: multi-agent enhancement learning, dangerous vehicle early warning, active protection, intelligent wearing equipment, early warning algorithm, fuzzy comprehensive evaluation
