柳南高速改扩建交通组织分析

Analysis of Traffic Organization during Reconstruction and Expansion of Liu-Nan Expressway

以柳南高速改扩建项目为实例,分析了改扩建道路以及周边可作为分流路径道路的现状,提出了切合实际的交通组织方案,并提出了三级分流方案设计。针对路段、互通、桥梁等临时施工点,提出了临时交通安全实施设置策略,充分保障了改扩建期间施工安全性,提高了车辆通行效率。

In this paper, in the empirical case of the reconstruction and expansion project of the Liu-Nan expressway, we analyzed the sections to be reconstructed or expanded and the surrounding routes capable of acting as the detour, proposed a practical traffic organization scheme and the three-grade traffic flow diversion plan, and at the end, considering the temporary construction sites on road sections, interchanges and bridges, proposed the temporary traffic safety measures for the working period.
