Optimal matching for ridesharing systems with endogenous and flexible user participation

Nikolaos Geroliminis, Zhenyu Yang

The performance of ridesharing systems is intricately entwined with user participation. To characterize such interplay, we adopt a repeated multi-player, non-cooperative game approach to model a ridesharing platform and its users’ decision-making. Users re ...

Optimizing multi-modal ride-matching with transfers

Nikolaos Geroliminis

One of the limitations of ride-sharing is that matched drivers and riders need to have similar itineraries and desired arrival times for ride-sharing to be competitive against other transport modes. By allowing a single transfer at a designated transfer hu ...
