高速公路隧道交通事故规律研究

目前我国高速公路隧道内时常发生交通事故,为研究其特点和规律,收集2 193起高速公路隧道交通事故资料,对这些资料数据进行统计,分析隧道中交通事故的时间和空间分布特征、事故形态、事故车型以及发生原因。结果表明:一天中的9:00~10:00、11:00~12:00、13:00~15:00是交通事故的频发时段,周末发生的交通事故数约占总数的40%,1、2、4、5、7月易发生交通事故;追尾和碰撞隧道壁是隧道交通事故的主要形态;违章超速和天气变化是导致事故发生的主要原因;交通事故的车型主要为底盘较轻的轿车和重型货车。

Study of Rules of Traffic Accidents in Expressway Tunnels

The traffic accidents often occur in expressway tunnels in China nowadays. As a result, the characteristics and rules of traffic accidents in expressway tunnel are studied by collecting traffic accidents in expressway tunnels and analyzing the temporospatial distribution rules, types, vehicle types and causes. The results show that: 1) The high incidence time sections of single day are 9:00 to 10:00, 11:00 to 12:00 and 13:00 to 15:00. The proportion of traffic accidents occurred on weekends is about 40%. Traffic accidents occurred in January, February, April, May and July are more than those in other months. 2) The traffic accident modes in expressway tunnel are mainly vehicle rear end and collision. 3) The main causes of traffic accident are overspeed of vehicle and weather. 4) The vehicles, prefer to cause traffic accident, are cars with light chassis and heavy trucks.
