近日,上海同济大学召开中德道路信号灯研讨会, 与会专家指出:红绿灯间隔时间设计不合理是造成行人乱穿马路难以解决的原因之一,行人等待红灯的忍耐极限,德国人是60秒, 英国人是45秒,上海有的地方红灯64 秒,有的地方竟达126秒。中国行人的红灯时间为什么比外国长?姑且不论英德等国是否同样“机非混行”,也不论我国一些城市的路况 Recently, Shanghai Tongji University held a Sino-German road signal seminar. Experts attending the conference pointed out that the unreasonable design of the traffic light interval is one of the reasons that pedestrians can not easily solve the problem of crossing the street. Pedestrians wait for the endurance limit of the red light. The Germans are 60 seconds, The British are 45 seconds, 64 seconds red light in some places in Shanghai, and some as long as 126 seconds. Why the red light time of Chinese pedestrians is longer than that of foreign countries? Regardless of whether the United Kingdom, Germany and other countries are equally “non-intermingled” and regardless of the traffic conditions in some Chinese cities
