摘要: 行人主动安全系统能够有效降低人车碰撞风险,但其对交通流长时间运行状态的影响有待探究。运用Net Logo软件,基于智能体建模思想设置车辆和行人运动模式,选择平均车速波动情况和车辆等待时间、行人等待时间、行人速度分布评估传统车辆、行人检测系统车辆和人车通讯系统研究车辆运行时的交通流稳定性和通行效率。研究结果表明:行人主动安全系统在不同道路条件下的性能互有差异;行人检测系统的使用不利于交通流运行的稳定性;人车通讯系统的普及可能影响车辆通行效率,加剧城市拥堵。研究为驾驶人培训、自动驾驶车辆市场准入、道路设计和管理等方面提供思路。

Abstract: Pedestrian active safety system can effectively reduce the risk of collision between pedestrians and vehicles, but its impact on the long-term operation state of traffic flow remains to be explored. Net Logo software was used to set the motion modes of vehicle agents and pedestrian agents based on the idea of agent-based modeling. The average vehicle speed fluctuation, vehicle waiting time, pedestrian waiting time and pedestrian speed distribution were selected to evaluate the traffic flow stability and traffic efficiency while traditional vehicles, vehicles with pedestrian detection system and vehicles with pedestrian-vehicle communication system were running. The results show that the pedestrian active safety system has different performances under different road conditions. The use of pedestrian detection systems is not conducive to the traffic flow stability. The popularity of pedestrian-vehicle communication systems may affect traffic efficiency and increase urban congestion. The study provides ideas for driver training, automatic driving vehicle market access, road design and management.

Key words: transportation engineering, advanced driving assistance system, pedestrian protection, traffic flow stability, traffic efficiency, Net Logo simulation platform
