Abstract

In this study, we present an on-demand system in order to improve the efficiency of a single bus line facing a clear demand imbalance during peak hours. The on-demand system aims to increase the efficiency of service by allowing vehicles to take shortcuts between the city center and the terminal given the set of passenger requests known at the time. Passengers indicate their origin, destination, and desired pick-up time through an app or an online platform. Since the passenger requests are explicitly taken into account, each passenger is assigned to a service that serves their origin and destination. This assignment is also communicated to the passengers some time before their desired departure time. Given the practical importance of efficiently optimizing the decisions of this system in a short time, a VNS algorithm is developed. The algorithm decides which shortcuts to take by each bus and in each direction, when to depart from the city center and the terminal, and the corresponding passenger assignments in a matter of minutes. The performance of the system is analyzed under different circumstances.
