摘要:

道路交通是国民经济和社会发展的命脉,提升道路交通系统韧性是打造宜居韧性智慧城市的关键举措。随着城镇化进程加快,城市面临的不确定性因素交织叠加,频发的自然灾害、重大活动、公共安全事件等对韧性道路交通系统建设提出了更为迫切的要求。文章对道路交通系统韧性的内涵进行了概述,梳理了国内外道路交通韧性从理念引入、政策支持到技术应用的3个发展阶段,围绕系统韧性规划体系、多维度韧性评估、动态推演与演化机制、应急组织与协同管控,凝练总结了韧性提升在道路规划、设计、管控、运行维护等全环节的关键挑战。最后,从加强顶层规划和统筹设计、攻克核心科学问题和关键技术、健全法律法规和标准化技术文件、加速推进技术成果落地应用4个方面提出了中国道路交通系统韧性发展建议。

Abstract:

Road transportation system is the lifeline of the national economy and social development. Enhancing the resilience of the road transportation system is a key initiative to build a livable and resilient smart city. As urbanization accelerates, the interwoven complexities of extraordinary events become more pronounced in cities, encompassing a heightened frequency of natural disasters, mega-events, and public security incidents. These factors collectively underscore a pressing need for enhancing resilient road transportation systems. This paper provides an overview of the concept of road transportation system resilience and summarizes the three stages of global development in road transportation resilience, including the introduction of the concept, policy support, and technical application. Through the analysis of traffic demand in road planning, design, control, operation, and maintenance, this paper identifies the key challenges of resilience enhancement technology in four areas: system resilience planning system, multidimensional resilience assessment, dynamic deduction and evolutionary mechanisms, and emergency organization and collaborative management. Finally, the prospects of China’s road transportation resilience enhancement technology are proposed: Strengthening top-level planning and integrated design of resilient transportation, investigating core scientific issues and key technologies, perfecting laws and regulations and publishing technical standards and norms for resilience enhancement, demonstrating of the typical cities on the ground.
