摘要:为提升山区高速公路交通事故多发点鉴别水平，本文以滇东北某典型山区高速公路为研究对象，采集道路条件数据和2020-2021年的交通事故数据,分析交通事故分布情况及成因,针对性提出了基于改进事故频数法的山区高速公路交通事故多发点鉴别方法,并将其与交通事故实际分布情况对比以验证模型准确性,研究结果表明:①山区高速公路的交通事故多发路段主要分布在一般弯陡坡、急弯陡坡组合等先行不良路段;②以500m作为基于改进事故频数法的路段划分依据,交通事故多发点的鉴别结果的空间粒度更为精细;③后续研究将加强针对驾驶人的交通安全教育与宣传,提升交通执法力度,进一步提升山区高速公路的交通安全水平。
Abstract: In order to improve the identification level of traffic accident-prone poinls of expressways in mountainous areas, this paperlakes a typical mounltain highway in northeast Yunnan as the research object, collects moad condition data and traffic accident data from2020 to 2021,and analyzes the distribution and causes of traffic accidents. in this paper, an identification method of traffic accidlentfrequent points of mountain expressway hased on improved accident frequency method is put forward.And compare it with the actualdistribution of traffic accidents to verify the accuracy of the molel. The results show that: ① the traffic accident -pone sections ofexpressways in mountainous areas are mainly distributed in the first bad sections such as general curved steep slopes and sharp curvedsteep slopes, and②500m is used as the basis of road division based on the improved accident frequency method. the spatial gramularity ofthe identification results of traffic accident-prone pointls is more fine.③3 Follow-up research should strengthen trafic salfety education andpublicity for drivers, enhance traffic law enforcement, and further improve the traffic safety level of expressways in mountainous areas.
