Inferring mobility reductions from Covid-19 disease spread along the urban-rural gradient
The COVID-19 pandemic reshaped human mobility through interventions and voluntary behavioral changes. Those mobility reductions helped mitigate disease spread, but factors driving variation in mobility reduction remain unclear. We introduce a Bayesian hierarchical model to quantify heterogeneity in mobility responses across time and space in Germany's 400 districts using anonymized phone data. The model successfully reproduces timing and magnitud…
Shared pooled mobility: Expert review from nine disciplines and implications for an emerging transdisciplinary research agenda
Shared pooled mobility has been hailed as a sustainable mobility solution that uses digital innovation to efficiently bundle rides. Multiple disciplines have started investigating and analyzing shared pooled mobility systems. However, there is a lack of cross-community communication making it hard to build upon knowledge from other fields or know which open questions may be of interest to other fields. Here, we identify and review 9 perspectives:…
Toward identifying the critical mass in spatial two-sided markets
Unlike their nonspatial counterparts, spatial multi-sided platforms are matchmaking platforms with an additional layer of complexity: their customers expect to meet in space, not only virtually. This additional challenge will be studied in this paper in the context of a two-sided ride-sharing platform, which serves drivers and passengers. As with any two-sided platform, there is an interdependence between both groups of customers: More drivers ar…
The end of travel time matrices: Individual travel times in integrated land use/transport models
To reduce inaccuracies due to insufficient spatial resolution of models, it has been suggested to use smaller raster cells instead of larger zones. Increasing the number of zones, however, increases the size of a matrix to store travel times, called skim tables in transport modeling. Those become difficult to create, to store and to read, while most of the origin-destination pairs are calculated and stored but never used. At the same time, such a…
Simultaneous internalization of traffic congestion and noise exposure costs
Income-contingent user preferences in policy evaluation: Application and discussion based on multi-agent transport simulations
Virtual Worlds—Real Decisions: Model- and Visualization-based Tools for Landscape Planning in Switzerland
Prominent construction projects in Switzerland, such as the Sawiris luxury resort in Andermatt planned by Orascom Hotels & Development, Cairo (Egypt), or the idea of a hotel and apartment tower at Schatzalp, Davos, demonstrate how rapidly Alpine landscapes may undergo major changes. Decisions on whether or not such changes are supported by policymakers should be based on the best information available and in agreement with the local population to…
