【摘要】：为进一步预防和控制连续下坡路段交通事故,探讨其时空分布特征。针对连续下坡路段交通安全问题突出的特点,根据某高速公路典型连续下坡路段的交通事故统计资料、道路线形指标和交通量,分析该路段交通事故时空分布特征。采用相关性分析方法,探讨潜在影响因素与连续下坡路段交通事故时空分布的相关性。研究结果表明,在8∶00—10∶00时,小时事故率、死亡率和受伤率均达到最大;当连续下坡路段长度不超过3 km时,连续下坡对事故率、死亡率和受伤率基本无影响;随着路段长度的增加,合理地设置避险车道有助于减少事故率、死亡率和受伤率;但当路段长度超过9 km时,设置避险车道等防护措施对事故率、死亡率和受伤害率的影响均不明显。
[Abstract]:In order to further prevent and control traffic accidents in continuous downhill sections, the temporal and spatial distribution characteristics of traffic accidents are discussed. According to the characteristics of traffic safety problems in continuous downhill sections, according to the traffic accident statistics data, road alignment index and traffic volume of a typical downhill section of expressway, the space-time distribution characteristics of traffic accidents in this section are analyzed. The correlation analysis method was used to study the correlation between the potential influencing factors and the temporal and spatial distribution of traffic accidents in continuous downhill sections. The results show that at 8: 00-10: 00, the hourly accident rate, mortality rate and injury rate reach the maximum, and when the length of the continuous downhill section is less than 3 km, the continuous downhill section has no effect on the accident rate, mortality and injury rate. With the increase of the length of the road section, setting up the safe lane reasonably helps to reduce the accident rate, mortality rate and injury rate. However, when the length of the road is longer than 9 km, the protective measures such as setting up safe havens have no obvious effect on the accident rate, mortality rate and injury rate.
