交通管理的任务是维护道路交通秩序,保障交通安全畅通。雾天,道路能见度下降,驾驶员的视线受到很大影响。尤其是浓雾的时候,能见度极低,严重影响了驾驶员的观察力和判断力。由于高速公路具有车流量大、行车速度快的特点,因雾引起的交通事故明显多于普通公路,且经常是多车连环追尾相撞的重、特大恶性交通事故,如:1975年,美国加里福尼亚至纽约的高速公路,由于大雾引起的一场世界上最大的交通事故,造成300多辆汽车相撞,近千人伤亡。另一方面,雾的分布具有不均匀性,高速公路沿线各段能见度不同,驾驶员又很
The task of traffic management is to maintain the traffic order and ensure the traffic safety. Foggy days, the road visibility decreased, the driver’s line of sight has been greatly affected. Especially when fog, visibility is very low, seriously affecting the driver’s observation and judgment. As the highway has the characteristics of large traffic volume and fast driving speed, the traffic accidents caused by the fog are obviously more than those of ordinary roads, and are often the serious and vicious traffic accidents caused by multi-car rear-end collisions. For example, in 1975, Highway from Fornia to New York, a world’s largest traffic accident caused by heavy fog, caused more than 300 vehicles to collide with nearly a thousand casualties. On the other hand, the fog distribution is not uniform, visibility along the highway along the different sections, the driver is very
