Revealing the Spatial Preferences Embedded in Online Activities: A Case Study of Chengdu, China

Online activities based on various social media applications are gradually becoming a vital social activity issue in the mobile Internet era. This study aims to reveal the spatial preferences embedded in this new type of urban life to better plan and design future cities. With two different types of social media data—online location tagging from Weibo and online reviews of POIs on Dianping—we conducted a quantitative analysis to explore the relationship between online activities and the built environment elements. The results suggested that online activities remain associated with urban entities, and the activity represented by Dianping reviews revealed more significant spatial preferences than that described by Weibo check-ins. The results also showed similarities and differences between spatial choices of those who engage in these two activities. These findings allow for an in-depth understanding of contemporary cities complexity and provide new opportunities for integrating cyberspace and city space.

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.

Large-scale Evaluation for Street Walkability

Methodological Improvements and the Empirical Application in Chengdu

The significant effect of walking on urban sustainability has attracted worldwide attention. More and more walkability evaluation studies have been conducted in recent years. In this paper, we revised the evaluation method for WalkScore via introducing street greenery and applied the revised method in Chengdu. The application results reveal that streets in residential areas are associated with greater WalkScore, in comparing with those in business areas. In addition, streets being closer to the city center, sub centers, subway stations and shopping centers have greater WalkScore values as well.
