“行人保护”是美国于上世纪60年代最先提出的一个概念,目的就是为了减少交通事故中车辆对行人的伤害。从当前的交通安全状况来看,这无疑具有超前性,但在这一概念提出后的几十年中,相关技术与法律法规的跟进似乎却并不尽如人意。 “Pedestrian Protection ” is the concept first proposed by the United States in the 1960s. The purpose is to reduce the damage to pedestrians caused by vehicles in traffic accidents. Judging from the current traffic safety situation, this is undoubtedly advanced. However, in the decades after the concept was put forward, the follow-up on relevant technologies and laws and regulations seems to be unsatisfactory.
