Abstract:

Traffic design systematically optimizes the functionality and performance of existing and future transportation systems and facilities. Positioned after traffic planning and preceding traffic management and services, traffic design is crucial for achieving the optimal utilization of transportation systems and facilities. It holds equal significance to urban design and industrial design. With the implementation of the nationwide “Smooth Traffic” plan by the Ministry of Public Security and the Ministry of Housing and Urban-Rural Development (formerly the Ministry of Construction), in the year 2000, traffic design theories and methodologies have been formally introduced and continuously developed and promoted in China. Its role and value have become increasingly prominent with the growing need for refined road traffic construction, as well as urban restoration and updates. The resulting benefits of optimizing and enhancing transportation systems have gained global recognition. This paper systematically outlines the development history, representative achievements, and the latest progress in traffic design technology. Addressing four main technical challenges, including the intensification of supply-demand conflicts, the enhancement of transportation development quality, the miniaturization and intelligence of new models of vehicles, and the uncertainties of traveler behaviors in a connected information environment, this paper identifies the future directions of traffic design technologies. With the goal of realizing the strategy of building a strong transportation nation where “people enjoy their journeys, and goods flow smoothly”, this paper puts forward development strategies from five aspects, including construction processes, administrative mechanisms, fee standards, standards and regulations, and professional qualifications.

摘要：

交通设计是对现有和未来建设与发展的交通系统及其设施的功能、性能加以系统性优化设计，上承交通规划，下接交通管理与服务，横向对接土木工程设计，是实现交通系统与设施资源最佳化的关键，与城市设计和工业设计具有同等重要意义。伴随着公安部、住房和城乡建设部在全国范围内“畅通工程”计划的实施，交通设计理论和方法于2000年在中国正式被全面系统性地提出并不断发展、推广，其作用和价值在道路交通高质量建设与城市修复及更新重大发展中愈发凸显，所带来的交通系统优化建造与改善成效也在世界范围内获得认可。文章系统地梳理了交通设计技术的发展历程、代表性成果及最新进展；针对供需矛盾尖锐化、交通发展品质化、新型汽车小型化与智能化、网联信息环境下出行者行为不确定性4个方面的技术挑战，指出了未来交通设计技术攻关方向；面向交通强国建设战略“人享其行、物优其流”的目标，从建设流程、行政机制、收费标准、标准规范、职业资质5个方面提出了发展对策建议。
