Traffic systems are so important that they shape the form of cities. And yet the growing number of vehicles in high-density cities creates a situation that places pedestrians in direct competition with vehicles for space, especially in city centers. Current methods, such as underground and elevated walkways, are just passive measures. They do not integrate pedestrian, vehicular and building systems and therefore are not conducive to a city’s street life. At best, these systems still leave pedestrian traffic intermittent and discontinuous, instead of streamlining the flow of people and goods. Buildings play vital roles in urban space, such as offering public space within buildings, supporting the function needed by the public, improving the environment of public space, and working as nodes to reconcile the contradiction between vehicles and pedestrians. In order to implement these roles, a symbiotic relationship between pedestrian systems and buildings is required. Currently in China, functions are highly concentrated in city centers and cities are developing towards a high-density, which leads to the development of three-level traffic systems especially in city centers. In the process of weaving together new building and traffic infrastructure, China has a great opportunity to establish pedestrian systems that are integrated with buildings. The main work of the paper is listed below: (1) With the analysis of the successful pedestrian systems of Hong Kong, Bangkok and Boston, I summarized a variety of connection methods between buildings and pedestrian systems, as well as several ways that multi-function buildings support pedestrian systems. After that, the Assessment Methodology was proposed in terms of the three precedents together with related theories. (2) By implementing the Assessment Methodology on three city centers in Shanghai (Wujiaochang, Yangpu District, Lujiazui, Pudong District and Xujiahui, Xuhui District), I summarized the merits and demerits of each urban center. (3) I proposed the design strategy for the symbiotic relationship between pedestrian systems and buildings on the basis of previous analysis of Hong Kong, Bangkok and Boston, together with the three city centers in Shanghai. (4) Basing on the 5 design strategies, I proposed a design for one site within Wujiaochang. I integrated buildings and pedestrian systems to create a convenient, II desirable and dynamic place for pedestrians, as well as solve the existing challenges of pedestrian systems in the entire area. The symbiotic relationship between pedestrian systems and buildings is to clarify the role of buildings in pedestrian systems, allowing buildings to serve as essential nodes, and integrate with the pedestrian systems. Thus, it would contribute to the continuity of pedestrian behavior and offer functional support, enhance the efficient and comfort level for pedestrian, stimulate more socializing and activities in public space, and therefore will improve the street culture. Especially in high-density cities, buildings can be utilized to interconnect the pedestrian systems on elevated, ground, and underground levels, contributing to safe, convenient and desirable walking environment. Hence the symbiotic relationship between pedestrian systems and buildings will help to address the problems found in existing pedestrian systems within high-density cities.
