Reversed urbanism: Inferring urban performance through behavioral patterns in temporal telecom data

Abstract

A fundamental aspect of well performing cities is successful public spaces. For centuries, understanding these places has been limited to sporadic observations and laborious data collection. This study proposes a novel methodology to analyze citywide, discrete urban spaces using highly accurate anonymized telecom data and machine learning algorithms. Through superposition of human dynamics and urban features, this work aims to expose clear correlations between the design of the city and the behavioral patterns of its users. Geolocated telecom data, obtained for the state of Andorra, were initially analyzed to identify "stay-points"-events in which cellular devices remain within a certain roaming distance for a given length of time. These stay-points were then further analyzed to find clusters of activity characterized in terms of their size, persistence, and diversity. Multivariate linear regression models were used to identify associations between the formation of these clusters and various urban features such as urban morphology or land-use within a 25-50 meters resolution. Some of the urban features that were found to be highly related to the creation of large, diverse and long-lasting clusters were the presence of service and entertainment amenities, natural water features, and the betweenness centrality of the road network; others, such as educational and park amenities were shown to have a negative impact. Ultimately, this study suggests a "reversed urbanism" methodology: an evidence-based approach to urban design, planning, and decision making, in which human behavioral patterns are instilled as a foundational design tool for inferring the success rates of highly performative urban places.

Mobility and COVID-19 in Andorra: Country-scale analysis of high-resolution mobility patterns and infection spread

“…Until recently, gathering fine grained movement patterns data for large populations of people was nearly impossible [31]. With the advent of GPS-enabled smartphones, most people around the world today are continuously generating data on their mobility patterns.…”

The amenity mix of urban neighborhoods

“…In recent years urbanism has witnessed the growth of parametric and generative design approaches (Mehaffy, 2008;Nagy et al, 2018;Schumacher, 2009). These approaches, which leverage new computational tools and big data, are helping optimize the form (Alonso et al, 2019;Noyman et al, 2019), energy efficiency (Nagy et al, 2018), and walkability of neighborhoods (Rakha & Reinhart, 2012;Sonta & Jain, 2019, pp. 454-461).…”

Towards Sustainable Heritage Tourism: A Space Syntax-Based Analysis Method to Improve Tourists’ Spatial Cognition in Chinese Historic Districts

“…The VGA results of the selected block based on four view locations were reported in Figure 6 where the white eye symbol denotes the view of one tourist. The red space is the space that the pedestrians need to take more turns on the route through the block to see, and hence takes longer to be revealed and become available for tourists [34]. Based on Kaplan's research [35], the red space has greater depth and enhanced mystery.…”

“…Then, from the north and west perspectives, much more space is available for tourists in terms of visibility. be revealed and become available for tourists [34]. Based on Kaplan's research [35], the red space has greater depth and enhanced mystery.…”
