Minimizing waiting times at transitional nodes for public bus transportation in Greece

Scheduling of transit networks is one of the most addressed problems in the mathematical optimization science, due to the increase of public transportation in the last decade. Researchers have introduced various formulations to address the problem of timetabling, using different objectives like bus synchronization and passenger demand. In this paper, we present a mixed-integer linear programming formulation with the objective of minimizing passenger waiting times at transitional transfer nodes, taking also into consideration high passenger demand that occurs at certain times.
