C规划：沧州市步行和自行车友好街巷规划设计

通过比较全球近60座城市的交通发展模式，针对中国中小城市以步行和自行车交通为主的出行特征，提出C模式概念，即步行和自行车导向型交通模式。以河北省沧州市为例，分析C模式下的典型问题与居民出行需求。基于此，提出适应步行和自行车交通发展的C规划3C理念，即具有中国特色、步行和自行车友好、跨越用地边界的街道规划。C规划的重点是利用并连通既有城市支路与街巷，形成步行和自行车优先通行的廊道网络；C设计的重点是基于步行和自行车交通特征和公众意愿，通过跨界设计实现不同出行群体的和谐共生。以沧州市核心区为例进行规划实践并展示典型街巷设计案例。

C Plan:Pedestrian & Bicycle-Friendly Street Planning and Design in Cangzhou City

Through comparing transportation development patterns in nearly 60 cities of the world, this pa-per proposes C Mode (pedestrian&bicycle-oriented transportation pattern) concept according to the travel characteristics of small and medium-sized Chinese cities where walking and bicycling are main travel modes. Taking Cangzhou in Hebei as an example, the paper analyzes the typical problems and residents' travel demand under C Mode, based on which a“3C”principles is proposed to accommodate pedestrian and bicycle transportation development. This 3C principle reflects the unique Chinese characteristics in pe-destrian&bicycle-friendly design, and street planning beyond land use boundary. Utilizing and connecting the existing local roads and streets, C Plan focuses on developing the corridor network with the prioritized pedestrian and bicycle travel. Based on characteristics of pedestrian and bicycle travel and general public preferences, C Design emphasizes the coordination among various travel communities for traveling harmo-niously. The paper presents the case studies of street design and planning practice for Cangzhou core area.
