Service Quality Paradox -- Guaranteeing early deliveries causes overall delays in ride pooling services — •Philip Marszal1,2, Marc Timme1,2,3, and Malte Schröder1,2 — 1Center for Advancing Electronics Dresden (cfaed), Technical University of Dresden, 01062, Dresden, Germany — 2Institute for Theoretical Physics, Technical University of Dresden, 01062, Dresden, Germany — 3Lakeside Labs, Lakeside B04b, Klagenfurt, 9020, Austria
On-demand ride pooling services become increasingly important for modern human mobility and rely on advanced forms of dispatching and coordination algorithms [1,2]. A central algorithm matches the vehicles of service providers to the trip requests of customers, aiming to efficiently combine passenger trips in order to reduce service time and distance traveled [3]. Here we reveal a service quality (SQ) paradox emerging emerging from how such services self-organize given a dispatching strategy: enforcing a maximum delay an individual passenger can experience may increase the average delay of all passengers. We quantitatively evaluate the SQ paradox in terms of the vehicle route flexibility, a measure of how many possible passengers may be served by a single vehicle. Our results theoretically revealed conditions underlying the novel paradox and may inform future designs of ridepooling algorithms to improve the service quality of the shared mobility ecosystem.
