摘　　要：通过对宁杭高速公路东庐山段2006年1月～2010年7月的交通事故资料的统计,从事故地点、事故时段、事故形态和事故车型等方面分析了上坡段交通事故的主要特征。研究发现:高速公路上坡段发生交通事故的风险要远大于下坡及其他路段;事故多发生在长大上坡段的中后部和竖曲线段;事故形态主要是追尾、撞护栏和撞固定物,而且重特大交通事故中追尾事故比例大;夜间的事故率和严重程度高于白天,尤其是凌晨02:00～06:00时为重特大交通事故高发期;大货车和小客车是坡段内交通事故的主要车型。上坡段事故的致因为疲劳驾驶、车辆速度离散性大、交通组成复杂。Based on traffic accident statistics during 2006 to July 2010 of East Lushan segment of Nanjing-Hangzhou Freeway,the characteristics of traffic accident on upgrade sections were analyzed from the view of accident site,accident period,accident form and accident vehicle type.The study shows that the freeway upgrade sections are more prone to traffic accidents than the downhill and the other sections.Accident always occurs in the middle and rear part of straight slope section and vertical curve segment.The accident forms are mainly rear-end,hitting guardrail or fixtures.It is worth mentioning that a large proportion of major traffic accidents are also rear-end.Accident rate and severity of accidents of the night are larger than those of the day.It is prone to have accident especially early in the morning from 2:00 to 6:00.Large trucks and small passenger cars are the main bodies of traffic accidents on freeway upgrade sections.The accident causes are fatigue driving,significant discreteness of speed and complicated traffic composition.
