基于区域路网协调的高速公路安全施工交通组织研究

高速公路改扩建过程中施工交通组织设计关系到施工安全和社会影响。以高速公路改扩建为例,采用区域路网协调的方法研究了交通组织设计路阻特性及起点-终点矩阵,利用分析软件Trans CAD对交通组织设计中的关键参数进行了模拟分析,以服务水平、环境影响、经济效益和安全性为评级指标建立了综合评级体系,最后结合安徽省区域内3条高速公路的扩建实例分析交通组织设计关键参数,以计算参数为依据对其交通组织设计进行了评价分析。

Study on Traffic Organization of Expressway Safety Construction Based on Regional Road Network Coordination

in the process of expressway reconstruction and expansion,construction traffic organization design is related to construction safety and social impact.Taking the reconstruction and extension of expressway as an example,this paper studies the road resistance characteristics and start end matrix of traffic organization design by using the method of regional road network coordination The key parameters of traffic organization design are simulated and analyzed by CAD.The comprehensive rating system is established with service level,environmental impact,economic benefit and safety as rating indexes.Finally,the key parameters of traffic organization design are analyzed based on the expansion of three expressways in Anhui Province.
