Characteristics and Countermeasures of Traffic Accidents in Expressway Tunnel

摘要: 为探讨公路隧道交通事故的发生机理及防范对策,对浙江省10条高速公路隧道进行了调研,收集交通事故599次,抛锚5280次.基于调研数据,分析了公路隧道交通事故的形态分布、交通事故的车型构成与原因以及隧道百万车公里交通事故率等.研究了交通事故率与隧道交通量,追尾、火灾、翻车、撞壁事故率与隧道交通量之间的关系,给出了交通事故率与隧道交通量、追尾事故率与隧道交通量关系的拟合公式以及隧道交通事故的防范措施,为进一步研究隧道交通事故的发生机理,避免特大、重大等恶性交通事故提供了参考.Abstract: In older to probe into the mechanism and countermeasures of traffic accidents in expressway tunnels,10 expressway tunnels in Zhejiang Province were investigated,and the data of 599 traffic accidents and 5 280 anchorage accidents were collected.Based on these data,composition of traffic accidents,the relation between them and vehicle types and accident rate per million vehicle kilometer (MVK) were analyzed.The relationships between traffic accidents,fire accidents,rear-end accidents,wall colliding accidents and vehicle roll-over accidents with traffic volumes were investigated,and their fitting formulas were given.Some countermeasures were suggested to decrease traffic accidents in expressway tunnels.The research provides a reference for the research on traffic accident mechanism to avoid worst and catastrophic traffic accidents.
