品质交通解读与深圳实践——以深圳市福田中心区街道品质提升为例

Overview of Quality Transportation and Its Practice in Shenzhen: A Case Study of Street Quality Improvement of Futian CBD, Shenzhen

街道环境恶化的问题在城市中正不断加剧,以往对品质交通的关注点多集中在交通量计算、拥堵难点治理、优化车道分配等,对道路功能包含的城市景观与市民活力的思考不足。首先从时代背景、道路功能演变、街道建设标准和要求等方面阐述交通品质化的历史发展沿革。结合深圳市民出行需求变化,探索新时代市民对品质交通的需求。以深圳市福田中心区交通设施及空间环境提升项目为例,从绿色低碳交通的发展需求和城市设计优化层面入手,分析并提出街道环境品质提升的整体思路,并针对道路设施存在的问题提出街道品质提升的策略和具体措施。指出既要在有限的道路横断面中妥善考虑步行、自行车与机动车交通的均衡,同时又要对道路沿线的碎片化空间整体考虑,并统一纳入景观化改善提升。

The deterioration of street environment is increasingly a problem in cities. In the past, the focus on the performance of traffic flow was concentrated on traffic volume, management of congestion hot spots, optimization of lane allocation, etc., yet consideration on urban landscape and citizen- friendliness that ought to be coordinated with road functions was insufficient. This paper illustrates the historical development of traffic quality from the perspectives of the historical background, the evolution of road functions, as well as the standards and requirements of street construction. Taking the changes in the travel needs of Shenzhen citizens into account, we explore the demand for qualified transportation in the new era. Taking the transportation facilities and space environment improvement project of Futian CBD in Shenzhen as an example, starting by dealing with the development demand for green low-carbon transportation and urban design optimization, the paper analyzes and proposes the overall idea of street environmental quality improvement, along with strategies and specific measures of street quality improving, in response to problems existing in road facilities. It points out that the balance of walking, bicycle and motor vehicle traffic should be properly considered in the limited cross-sections of the roads. At the same time, the fragmented roadside space should be utilized in coordination with the overall design, integrated into the landscape improvement.
