• Abstract summary: We use app-usage data as a digital signature to investigate the relationship between online app usage and urban vibrancy. To do this, we use a high-resolution data source of mobile service-level traffic volumes across eighteen cities in France. Across cities, there were spatial behavioural archetypes, characterised by multidimensional properties.

• Abstract: Urban vibrancy is an important measure of the energetic nature of a city that is related to why and how people use urban spaces, and it is inherently connected with our social behaviour. Increasingly, people use a wide range of mobile phone apps in their daily lives to connect socially, search for information, make decisions, and arrange travel, amongst many other reasons. However, the relationship between online app usage and urban vibrancy remains unclear, particularly regarding how sociospatial behaviours interact with urban features. Here, we use app-usage data as a digital signature to investigate this question. To do this, we use a high-resolution data source of mobile service-level traffic volumes across eighteen cities in France. We investigate the social component of cities using socially relevant urban features constructed from OpenStreetMap 'Points of Interest'. We developed a methodology for identifying and classifying multidimensional app usage time series based on similarity. We used these in predictive models to interpret the results for each city and across France. Across cities, there were spatial behavioural archetypes, characterised by multidimensional properties. We found patterns between the week and the weekend, and across cities, and the country. These archetypes correspond to changes in socially relevant urban features that impact urban vibrancy. Our results add further evidence for the importance of using computational approaches to understand urban environments, the use of sociological concepts in computational science, and urban vibrancy in cities.

  Digitally acquired data can accurately capture complex human activity, but it lacks the interpretability of demographic data. We use a privacy-enhanced dataset of mobility visitation patterns of 1.2 million people to 1.1 million places in 11 metro areas in the U.S. We find lifestyles can be automatically decomposed into only 12 latent interpretable activity behaviors on how people combine shopping, eating, working, or using their free time.

  We organize an experimental campaign with video measurement in an area within the urban network of Zurich, Switzerland.

We propose a simple yet efficient Multiple Linear Regression (MLR) model to estimate travel times with fusion of various data sources.
