The aim of this study was to describe the position of pedestrians and pedal cyclists relative to the striking vehicle in the 3 s before impact. This information is essential for the development of effective autonomous emergency braking systems and relevant test conditions for consumer ratings. The UK RAIDS-OTS study provided 175 pedestrian and 127 pedal-cycle cases based on in-depth, at-scene investigations of a representative sample of accidents in 2000-2010. Pedal cyclists were scattered laterally more widely than pedestrians (90% of cyclists within around ±80° compared to ±20° for pedestrians), however their distance from the striking vehicle in the seconds before impact was no greater (90% of cyclists within 42 m at 3 s compared to 50 m for pedestrians). This data is consistent with a greater involvement of slow moving vehicles in cycle accidents. The implication of the results is that AEB systems for cyclists require almost complete 180° side-to-side vision but do not need a longer distance range than for pedestrians.
本研究的目的是描述行人与骑行者在碰撞前 3 秒相对撞击车辆的位置。该信息对于开发有效的自动驾驶紧急制动系统和相关的消费者评级测试条件至关重要。英国 RAIDS-OTS 研究基于 2000-2010 年期间具有代表性的事故现场深入调查，提供了 175 起行人事故和 127 起骑行者事故案例。骑行者在碰撞前 3 秒向侧面分散的范围比行人更宽（90%的骑行者在±80°范围内，而行人在±20°范围内），但他们与撞击车辆的距离没有更大（90%的骑行者在 3 秒内距离撞击车辆 42 米以内，而行人的距离为 50 米）。该数据与涉及低速行驶车辆的更多自行车事故一致。研究结果表明，自行车的 AEB 系统几乎需要完全 180°的侧视范围，但不需要比行人更长的距离范围。
