Anomalous Diffusion in Ridesharing? — •Philip Marszal, Malte Schröder, Nora Molkenthin, and Marc Timme — Chair for Network Dynamics, Institute for Theoretical Physics and Center for Advancing Electronics Dresden (cfaed), TU Dresden
A multitude of new transport approaches hold a promise of more flexible and more sustainable mobility. Ridesharing, combining trips to simultanenously share rides of several people on the same vehicle, aims to reduce the number of vehicles on the street and the distance traveled by each individual vehicle. Despite already being offered by service providers, the collective dynamics of ridesharing systems are not well understood. Here we study the spatio-temporal dynamics of ridesharing buses by interpreting their routes as random walks whose properties depend on the system size and load. We identify scaling relations characterizing the area served by a bus and its effective velocity, changing from ballistic trajectories on short timescales to anomalous diffusive motion on long timescales. As differences in scaling drastically affect system performance, these insights suggest a novel path towards optimizing ride-sharing systems.
