基于对美国运输规划实践活动的分析研究,本文提出运输政策指导下的四层次运输规划体系框架,即明确发展方向的战略规划、确定空间结构的布局规划、分清主次有序推进的发展规划和侧重工程和财务可行性分析的建设规划。建立该框架的意义在于发现运输规划系统中存在的不足和需要完善的领域;同时在规划实践中能够找准层次定位,发挥规划应有的作用。
Based on the analysis of the practical activities of transportation planning in the United States, this paper proposes a four-level transport planning framework under the guidance of transport policy, which is to define the strategic planning of the development direction, to determine the layout of the spatial structure, to distinguish the development planning of primary and secondary orderly development and Focus on engineering and financial feasibility analysis of the construction plan. The significance of establishing this framework lies in discovering the shortcomings in the transportation planning system and the areas that need to be improved. At the same time, we can identify the level of orientation in the planning practice and play its due role in the planning.
