Abstract: Barcelona, a model of urban public space construction，has paid much attention to the “people-oriented” construction concept in recent years, promoting the construction plan of “slow-moving city”. To meet the needs of urban walking accessibility, Barcelona has rezoned the urban slow-moving areas, planned the slow-moving networks connecting the segments, and made the networks also connected with the public transportation system. In the construction of the urban slow traffic network, the city has focused on the combination of green space networks and the slow traffic system, mainly applying the existing linear infrastructure such as roads, railways and river channels, and turning these spaces into connective multi-functional green axis spaces with the creative design. The implementation of this plan provides an important reference for the construction of slow-moving cities around the world, especially the reconstruction of the slow-moving system in urban built-up areas.
