Ride sharing - the bundling of simultaneous trips of several people in the same on-demand vehicle - may help to reduce the carbon footprint of human mobility. Yet, predicting the efficiency and sustainability of ride-sharing systems is hard due to their complex collective dynamics. Compared to individual motorized vehicle transportation, standard door-to-door ride sharing services reduce the total distance driven per user. However, they also increase the average travel times due to several additional stops and thus detours to pick up or drop off users. Here we show that requiring some users to walk to nearby shared stops reduces detours for the buses and thus the time users wait for their bus and drive in the bus. These time savings might overcompensate the additional walk time for the users. In this way, dynamic stop pooling reduces the average travel time and may break the trade-off between distance driven and travel time prevailing in door-to-door ride sharing. For example, ride sharing providers may reduce the fleet size to save distance driven without longer travel times when users walk a short part of their trip. Dynamic stop pooling may thus enable more sustainable ride sharing services without compromising service quality.
