摘要： 随着城镇化与机动化进程的快速推进，城市交通拥堵已成为制约大城市发展的突出问题。为 此，各大城市普遍通过编制综合交通规划，以明确未来城市交通发展战略并指导设施建设和交通管 理。其中，构建以快速道路和快速公共交通为核心的“双快”交通体系，已成为引导绿色交通发展 的重要战略。然而，大量实践证明，“双快”交通体系的内在目标存在矛盾：过度追求中心城区道 路交通快速化，反而会削弱公共交通的竞争力，导致小汽车出行比例上升，最终背离绿色交通的发 展初衷。结合国内外城市的实践案例，深入分析了城市交通系统中影响小汽车和公共交通方式竞争 的主要因素——出行时耗、出行成本和小汽车拥有率，系统剖析“双快”体系与城市交通发展战略 目标之间的辩证关系，进而为实现公共交通优先与绿色出行目标提出发展建议。

Reflections on Building a“Dual-Fast”Transportation System in Urban Transportation Development Strategies

Abstract： With the rapid advancement of urbanization and motorization, traffic congestion has become a major constraint on the development of large cities. In response, many cities have formulated comprehensive transportation plans to define future development strategies and guide infrastructure construction and traffic management. Among these strategies, the establishment of a“Dual-Fast”transportation system— centered on express roads and rapid public transit—has emerged as a key approach to advancing green transportation. However, extensive practices have shown that the objectives of this system can be inherently contradictory: excessive pursuit of rapid road traffic in central urban areas may weaken the competitiveness of public transit, increase the private car use, and ultimately deviate from the original goal of promoting green transportation. Based on domestic and international case studies, this paper presents an in-depth analysis of the key factors influencing the competition between private cars and public transit in urban transportation systems—travel time, travel cost, and car ownership rate. It systematically examines the dialectical relationship between the“Dual-Fast”transportation system and broader strategic goals of urban transportation development, and further proposes development recommendations for prioritizing public transit and achieving green mobility.
