高速公路改扩建作业区行车安全风险评价及临时安全防护体系研究
Research on Traffic Safety Risk Assessment and Temporary Safety Protection System in Expressway Reconstruction and Expansion Operation Area

针对现行规范体系不适应高速公路改扩建作业区临时交通安全防护的缺点，系统分析高速公路改扩建作业区工程特点及交通运行特征，构建了改扩建作业区行车安全风险指标体系，并运用灰色聚类评价方法对改扩建作业区行车安全风险分析，建立了改扩建作业区的六级风险评价体系，并提出了临时交通安全防护体系设置建议，为类似改扩建工程提供参考。
Aiming at the inadequacy of temporary traffic safety protection in the expressway reconstruction and expansion operation area, the engineering characteristics and traffic operation characteristics of the expressway reconstruction and expansion operation area are systematically analyzed. The driving safety risk index system of the reconstruction and expansion operation area is constructed, the grey clustering evaluation method is used to analyze the driving safety risk of the reconstruction and expansion operation area, the six-level risk evaluation system is established, and the suggestions for setting temporary traffic safety protection system are put forward, which can provide a reference for similar reconstruction and expansion projects.
