Abstract: With the rapid development of cities, the construction of urban slow-traffic systems has gradually become an important way to solve traffic congestion issue and promote the construction of healthy cities. As a linear factor, river corridors in cities have great potential to build slow networks, improve urban environmental quality, and enhance urban vitality. However, riverside sites in urban built-up areas often face many problems such as complex land use conditions, lack of space, and fragmentation by cities. The study aimed to build a high-quality urban riverside slow-traffic system with complex city functions, slow-moving comfort, and convenient surrounding connections. Four aspects were disscused including land and space combing, slow-traffic road section mode, slow-traffic mode, connection mode and slow-traffic service facilities to summarize the organization mode of the river corridor slow traffic system construction. The research of Houtang River in Ningbo was also taken as an example to explore the application of the mode in practical projects. Fimally, advices for future research and practical were proposed.
