Street Experiments and COVID-19: Challenges, Responses and Systemic Change.

Cities have introduced street experiments, among others, in order to cope with the urgent health challenges caused by the COVID-19 pandemic. They are primarily intended to allow people to move safely in urban spaces according to physical distancing requirements. It has been suggested that street experiments have the potential to not only respond to pressing needs, but to also trigger systemic change in mobility.

Detecting Hot Spots of Methane Flux Using Footprint-Weighted Flux Maps.

In this study, we propose a new technique for mapping the spatial heterogeneity in gas exchange around flux towers using flux footprint modeling and focusing on detecting hot spots of methane (CH) flux. In the first part of the study, we used a CH release experiment to evaluate three common flux footprint models: the Hsieh model (Hsieh et al., 2000), the Kljun model (Kljun et al.

Generational differences in spatial mobility: A study with mobile phone data.

This article focuses on generational differences in spatial mobility. Assuming that the ability to cope with the social transformations related to growing mobility varies significantly across generations, we use mobile positioning data collected in Estonia during 2014 providing four main indicators, namely, the number of locations visited and the distances between visited locations, within Estonia and abroad. The results indicate that spatial mobility declines linearly with age; however, a high degree of heterogeneity exists within age groups.
