设区市区县道公路网规模研究

Study on Regional County Road Network Scale

县道公路网规划推动着经济发展,承担着"上承国省干线,下接农村公路"的功能。以宿迁市为例,通过节点连通度法、国土系数法和弹性系数法的对比分析,确定最优化规模。从技术水平综合评价规模的合理性,进而宏观控制县道公路网的建设规模和结构等级。

The planning of county highway network which takes on the link of provincial trunk and rural way promotes the economic development. Taking the Suqian City as an example, through the analysis and comparison study of the node connectivity model, the coefficient method and elastic coefficient method, this study determines the optimal size of the regional networks. Then based on technology assessment, it evaluates whether the size is reasonable. Finally, it can macroscopically control the size of county road and the structure level.
