高速公路立交主线行车安全影响因素分析

Analysis of Factors Influencing Drive Safety on the Mainline of Expressway Interchange

以高速公路互通立交影响区域主线为研究对象,综合分析国内外在互通立交分流区、合流区、交织区安全方面的研究成果。从高速公路用户角度分析驾驶员在互通立交分流区、合流区驾驶行为变化规律,得出互通立交主线影响区域范围。基于人因工程分析各种形式互通立交主线影响区域范围内分、合流对驾驶员驾驶行为的影响,研究提出了对立交主线驾驶行为特性影响不同的6种典型互通立交分合流类型;从行车安全角度,系统剖析了互通立交主线行车条件安全综合影响因素及各因素对驾驶员驾驶行为特征的影响;为高速公路互通立交安全性评价提供依据,对高速公路互通立交安全性研究、建设和管理奠定基础。

The affected area mainline of the expressway interchange being the study objective,the research results on the aspects of the safety of diverging section,merging section and weaving section have been reviewed.The change laws of driving behaviors in these three sections mentioned above are analyzed and the influence range is proposed.Based on the human factors engineering,the impacts of diverging influence area and merging influence area on drivers＇ behaviors are studied from various interchanges.Six typical types of diverge and merge are put forward according to the drivers＇ characteristics.The comprehensive factors affecting the traffic safety are analyzed,and the impact of each factor on driving characteristics are studied,which provide the basis for safety evaluation of expressway interchange and lay a foundation for the research,construction and management of expressway interchange.
