典型交通设施对道路交通事故致因影响分析

Impact Analysis on Typical Transport Facilities to Causes of Road Traffic Accidents

在分析黑龙江省2006～2010年间1万多起道路交通事故数据的基础上，选取道路交通控制设施、路侧防护设施、道路物理隔离设施、照明设施等四类典型道路交通设施作为研究对象，分析不同敏感条件下（如不同道路类型、不同天气条件、不同事故形态、不同路表条件等）发生的交通事故形态与特征，据此分析道路交通设施对交通事故发生的影响情况，这将有利于道路交通设施功能的有效发挥，道路交通安全度的提高，也有利于道路交通设施的管理与维护。

Based on analysis of more than 10 ,000 traffic accidents data（2006~2010） ,the paper selects four typical road transport facilities （road traffic control facilities ,road side protection facilities ,road isolation facilities and road lighting facilities ） as the research object ,and establishes the relationship between these road transport facilities and traffic accidents under different conditions （for example , different road types ,different weather conditions ,different accident forms ,different road surface con-ditions ,et al） .And the intervention condition about several transport facilities to road traffic acci-dents is analyzed .These will be beneficial to the effectiveness of the road traffic facilities function , and to the improvement of the road traffic safety ,and to the management and maintenance of the road traffic facilities .
