高等级城市道路提升改造的决策要素与对策分析

Analysis of Decision-making Elements and Countermeasures for Upgrading and Reconstruction of High-grade Urban Roads in Putian

摘要:

随着我国城市化进程的发展，城市道路交通系统日渐成熟和完善。在此发展背景下，新增道路逐渐减少，既有道路改建提升的需求则日益增加。以城市快速路和主干路为主的高等级城市道路，因其重要的功能定位、复合的专业内容、高额的建设投资、广泛的社会影响，成为提升改建工作的重点。从莆田市荔港大道提升改造工程着手，详细剖析高等级城市道路在提升改建过程中所可能面临的复杂问题，并有针对性的对每个问题逐一给出详尽的解决方案，以探究高等级城市道路提升改建方案的决策方法。经过具体的案例分析，认为在高等级城市道路提升改造的方案决策时，应重点关注道路主体结构的改建目标，优先解决各专项工程的耦合问题，才能将复杂的改建任务抽丝剥茧，最终高效又经济的完成提升改造工作。

Abstract:

With the development of urbanization in China, the urban road transportation system has become increasingly mature and complete. Against this backdrop, the demand for new roads is gradually decreasing, while the need for upgrading and reconstructing the existing roads is rising. High-grade urban roads, primarily comprising urban expressways and arterial roads, have become focal points of upgrading and reconstruction efforts due to their significant functional roles, complex professional contents, substantial construction investments and wide-ranging social impacts. Starting from the Putian Ligang Avenue Upgrading and Recosntruction Project, the complex issues that may arise during the upgrading and reconstruction of high-grade urban roads are analyzed in detail. And the detailed solutions to each problem one by one in a targeted manner are given to explore the decision-making methods for upgrading and reconstruction schemes of high-grade urban road. Through specific case analysis, it is concluded that in the decision-making process for upgrading and reconstruction schemes of high-grade urban roads, the special attention should be paid to the reconstruction goals of the main structure of the road, and the solution to the coupling problems of various special projects should be given priority to. Only in this way can the complex reconstruction tasks be unraveled step by step, and the upgrading and reconstruction work be completed efficiently and economically in the end.
