To solve the problem of low utilization of space under viaduct by sharing strategy

Abstract

Urban streets have undergone three major transformations in the last 350 years, corresponding to three characteristics: visual aesthetics and development, transportation infrastructure and efficiency, shared streets. Many of the city's basic elements like rivers, streets, viaducts play a crucial role in the city. The convergence of elements gives the site its uniqueness and shapes the living behaviour of its occupants. As a common urban element in the city, viaduct has a great influence on the urban spatial form. However, the space under the viaduct in China is lack of effective use and reasonable planning and difficult to pass efficiently. This paper will analyse and summarise the adaptive renewal design of the space under the viaduct based on the urban morphological characteristics, aiming at the water landscape and space idle problems of the space under the viaduct at the intersection of Siping Road and Zhongshan North Second Road in Shanghai. Based on the time-segment investigation and analysis of the space under viaduct at the intersection of Siping Road and Zhongshan North Second Road in Shanghai, various cases of space renewal under viaduct in foreign countries are specifically analysed for different problems and the activation direction and sharing strategy suitable for the characteristics of urban space in China are summarized by using typology method. The corresponding sharing strategies are concluded from the perspectives of transportation sharing, landscape sharing, activity sharing and space sharing. The sharing tendency under the influence of different urban elements will also be summarized. Based on the existing practical experience and field research, this paper summarizes the space under the viaduct under the influence of different urban elements and proposes several feasible and easy to promote teaching strategies to contribute to the shared renewal of urban street space under the viaduct.
