公路安全保障工程实施的安全措施改善了公路行车环境,对交通事故的分布也有显著影响,为明确其影响结果,针对某国道公路安全保障工程实施前一年周期和实施后第一年周期和第二年周期的事故分布特性进行了对比分析研究,包括事故相对多发路段的转移分析、整体事故比率转移分布分析、分道体和薄层铺装等设施对事故转移影响性分析等。分析结果表明,安全措施对事故分布有一定的影响,分道体等措施的实施效果与布设长度等因素相关。
In order to clarify the impact of road safety, the safety measures for highway safety and security engineering implementation improve the driving environment of road and have a significant impact on the distribution of traffic accidents. Year period of accident distribution characteristics were compared and analyzed, including the accident relatively multiple sections of the transfer analysis, the overall accident rate transfer distribution analysis, road and thin layer of pavement and other facilities on the impact of accidental transfer analysis. The analysis results show that the safety measures have a certain impact on the distribution of accidents, and the implementation effects of the measures such as traffic separation are related to the layout length and other factors.
