三级路网建设整体推进是公路交通可持续发展最有效的途径之一。通过回顾过去 2 0年和展望未来 10年公路交通的发展 ,对三级路网进行了界定 ,提出要在综合运输体系中不断保持和提高公路交通的“核心竞争能力”,一个良好的三级路网建设的整合发展计划能最大限度发挥公路运输的网络效应 ,而这种规划理念则要求公路交通建设发展的重点从规模转向结构。文章明确提出 :在三级路网的实际规划中要注重各层次路网规划 ,特别是节点规划的协调 ,通过这种规划对沿线的土地和空间资源的资本进行调控 ,从而促进地区社会、经济、环境和综合运输的可持续发展
The overall promotion of tertiary network construction is one of the most effective ways of sustainable development of highway traffic. By reviewing the development of road traffic in the past 20 years and looking ahead to the next 10 years, the three-level road network has been defined, and the “core competitiveness” of maintaining and improving road transport in the integrated transport system has been proposed. A good three-level The integrated development plan for road network construction can maximize the network effect of road transport, and this planning concept requires that the focus of highway traffic construction development shift from scale to structure. The article made clear: in the actual planning of the three-level road network should pay attention to the various levels of road network planning, especially the coordination of node planning, through this planning on the land and space resources along the capital regulation, thereby promoting the region’s social and economic , Environment and sustainable development of integrated transport
