冯店隧道交通事故特性研究

文章分析了成南高速公路冯店隧道交通事故的时空分布特性。冯店隧道（79～80km）的交通事故主要集中于79．62～80km路段、成都至南充（成南高速公路）方向，多数发生在夜晚，事故形态主要是撞击固定物和侧翻。分析了隧道、道路线形等因素对驾驶员的影响，认为隧道79～80km路段的线形组合和超速行驶不仅诱发事故、也是事故具有明显集中性、方向性和时间性的主要原因。

Astudy of traffic accident characteristics at Fengdian tunnel of Chengnan expressway

This paper analyzes the spatial-temporal distribution of traffic accidents in Chengnan Expressway Fengdian tunnel(79~ 80 km).These traffic accidents significantly concentrated in the 79.62~ 80 km section with a clear direction(Chengdu to Nanchong),mostly occurred at night,and their patterns are mainly colliding fixed objection and rollover.Based on the analysis of impact on drivers by factors such as tunnels,road alignment and so on,it concludes that the linear composition of tunnels of the 79~ 80 km sectio...
