Fix or flex? How ridepooling complements public transport — •Verena Krall1, Marc Timme1, 2, and Malte Schröder1 — 1Chair for Network Dynamics, Institute of Theoretical Physics & Center for Advancing Electronics Dresden (cfaed), TU Dresden, Germany — 2Lakeside Labs, Klagenfurt, Austria
Urban mobility is changing rapidly, not least due to the global rise of on-demand ridepooling services. In contrast to classic public transport with fixed lines and schedules, these new services offer a flexible shared transport with stops and routes determined by demand. This flexibility might attract new users to shared transport and offer higher accessibility to mobility in districts with poor public transport infrastructure. However, a complete shift from fixed line-based to flexible on-demand services would be detrimental, increasing congestion and wasting existing infrastructure. How can the two different service types complement each other to improve public transport? We find that the service quality is optimal if both line-based and on-demand transport are available. Additionally, we investigate adaptations of public transport networks and find that replacing inefficient lines step-by-step with on-demand vehicles may strongly reduce the overall costs. Applying our approach to empirical public transport networks, we identify lines that should be replaced with on-demand service. Our study shows how the combination of classic line-based with on-demand mobility may contribute to a public transport system that is both sustainable and user-friendly.
