New sources of economies and diseconomies of scale in on-demand ridepooling systems and comparison with public transport
Andres Fielbaum, Alejandro Tirachini, Javier Alonso-Mora
On-demand ridepooling (ODRP) can become a powerful alternative to reduce congestion and emissions, if it attracts private car users. Therefore, it is crucial to identify the strate…
Anticipatory routing methods for an on-demand ridepooling mobility system
Andres Fielbaum, Maximilian Kronmuller, Javier Alonso-Mora
One of the most relevant challenges regarding on-demand ridepooling relates to the spatial imbalances of the demand, which induce a mismatch between the position of the vehicles an…
How to split the costs among travellers sharing a ride? Aligning system's optimum with users' equilibrium
Andres Fielbaum, Rafal Kucharski, Oded Cats +1
How to form groups in a mobility system that offers shared rides, and how to split the costs within the travellers of a group, are non-trivial tasks, as two objectives conflict: 1)…
A Water-Filling Primal-Dual Algorithm for Approximating Non-Linear Covering Problems
Andrés Fielbaum, Ignacio Morales, José Verschae
Obtaining strong linear relaxations of capacitated covering problems constitute a major technical challenge even for simple settings. For one of the most basic cases, the Knapsack-…
