79~80 km等几个路段是成(都)南(充)高速公路第二辖区典型的交通事故黑点,114~120 km路段是事故发生的密集区域;周五发生的事故最多,周一次之,7月~9月是事故的高发月份;大、中型货车的事故率最高,乘用车次之,微型、轻型货车的事故率最低;除雾天外,雨天发生事故的概率最大,阴天次之,晴天最低。辖区内主要是单车事故,以碰撞固定物为主,多车事故主要以追尾碰撞为主。追尾碰撞占事故总数的比例为16.4%,但造成的伤、死亡人数均超过总数的60%以上。论文还结合“人、车、路和环境”等因素分析了事故成因,提出了相应的控制策略。
79 ~ 80 km and other sections are typical traffic black spots in the second area of the (South) (expressway) expressway (metropolitan area), 114 to 120 km of road sections are the dense areas where accidents occur; the most accidents occurred on Fridays and once a week July and September are the high incidence of accidents. The accident rates of large and medium-sized trucks are the highest, followed by passenger cars, and the accident rates of mini and light trucks are the lowest. The highest probability of accidents during the days of defogging and rainy days is cloudy, It’s sunny. The area is mainly a bicycle accident, collision-based fixed-based, multi-car accident mainly rear-end collision-based. The rear-end collisions accounted for 16.4% of the total number of accidents, but the number of injuries and deaths were more than 60% of the total. The thesis also analyzes the cause of the accident with the combination of “people, vehicles, roads and environment” and puts forward corresponding control strategies.
