Street Urbanism

We are working on Street Urbanism which is supposed to be a bridge to connect urban studies with planning & design. In addition to the overall introduction online shared, I also attach several recent publications by our group.

Street vibrancy and its impact factors: A case study in Chengdu

Streets as traffic carrier and public space of a city, are playing increasingly important role in daily city life. We quantitatively explore the street vibrancy of Chengdu, while referring to the street urbanism proposed by Ying Long and Yao Shen in 2015. We first define the concepts of street, vibrancy and street urbanism, followed by developing the factors for quantitatively evaluating street vibrancy at the street level. These factors range from function density, function diversity, accessibility to metro stations, distance to city center and sub-centers, to street level and width. Linear regression has been adopted for identifying the impact of each factor on the street vibrancy, which is measured by population density derived from mobile phone traces. We specifically analyze the impact factors for public administration and service streets (Type A), commercial streets (Type B) and residential streets (Type C). As one of first studies on evaluating street vibrancy and its impact factors for the whole city, we expect this paper could shed light on the future urban studies.

Picture Urbanism

Extensive studies have been conducted by academia on urban form related quantitative studies, most of which are at the grid or block levels. Emerging street view pictures (SVPs) provided by Internet companies like Google and Baidu enable users to virtually visit cities (on streets or even indoor) by navigating between immersive 360° panoramas. While SVPs provide convenient services for end users, they also shed light on helping researchers understand the human scale urban form which can be sensed by eye balls and touched by hands/feet. In contrast to conventional site surveys for a small place, such studies are also possible for an area with very large geographical coverage, thanks to the computation capacity of personal computers. In this talk, Dr Long will present his recent studies on using SVPs for measuring human scale urban form in terms of its geometry, quality, vibrancy, perform and their temporal dynamics.
