We develop a human-centric, data-driven approach for finding optimal bicycle infrastructure and network designs for metropolitan regions that help to shift trips from cars to bicycles. The framework exploits all modal shift potentials by incorporating trips of longer distances (e.g. commuters from/to suburban areas) and by differentiating the heterogeneous preferences of previously identified bicyclist types. In order to predict the impact of trip-specific bicycle infrastructure features on bicycle mode share as realistically as possible, we first reverse engineer the actual realized route and mode choice based on real data (e.g. origin-destination modal splits derived from mobile cell phone data, bicycle GPS trajectories). We also develop a data-driven model for bottleneck identification in existing bicycle networks. In all our models we incorporate expert knowledge and benchmark the quality of results with already existing approaches. The project develops, evaluates and compares analytical as well as robust spatio-temporal machine learning (ML) methods. Within a field study, we apply the approach to the Munich metropolitan area. We propose a bicycle infrastructure plan that helps authorities to sequentially implement individual measures leading to the modelled optimal bicycle infrastructure and network design. Finally, this plan is matched and compared with Munich's existing bicycle infrastructure plans and developments. Summing up, our approach will sustainably promote bicycle traffic on a larger scale and will thus increase public health [1] and decrease emissions, air pollution and space consumption [2].
