机荷高速公路平湖互通式立交改扩建方案研究

Study on Reconstruction and Expansion Scheme of Pinghu Interchange of Ji He Expressway

G15沈海高速公路深圳段(即机荷高速公路),为全国首例双层立体复合高速公路的改造工程。随着经济的持续发展、周边路网的不断完善,导致机荷高速的交通量飞速增长,服务水平直线下降,对其改扩建刻不容缓。机荷高速现状被交道路众多,相应的互通节点众多,故需充分结合整体改扩建计划、具体节点因素,对机荷高速平湖互通进行改扩建设计。经交通仿真模拟评估,推荐方案整体服务水平良好,运行通畅,满足远景交通量需求,同时满足机荷高速上下层之间的交通转换。

The Shenzhen section of G15 Shenhai Expressway(JiHe Expressway) is the first reconstruction project of double-layer and three-dimensional composite expressway in China. With the continuous economic development and the continuous improvement of the surrounding road network, the rapid growth of the traffic volume of the high-speed machine load and the linear decline of the service level have led to the urgent reconstruction and expansion of the machine load. The current situation of the machine load expressway is that there are many roads to be crossed, and there are many corresponding interworking nodes. Therefore, it is necessary to fully combine the overall reconstruction and expansion plan and specific node factors to carry out the reconstruction and expansion design for the Pinghu interworking of the machine load expressway. According to the traffic simulation evaluation, the overall service level of the recommended scheme is good, the operation is smooth, and it can meet the long-term traffic demand, as well as the traffic conversion between the upper and lower layers of the aircraft load expressway.
