Abstract: On-demand transportation (ODT) systems have proliferated in diverse cities worldwide due to their social, economic and environmental advantages. Despite those advantages, it is vital to get public approval. The approval key is the system’s reactivity in supplying speedy and reliable solutions that consider clients’ and vehicles’ constraints. Those solutions have to reflect actual life conditions to optimize the quality of service. The most regarded challenge in studying the ODT problem in cities is the stochastic time-dependent travel speed that varies due to traffic fluctuations. To deal with an actual ODT problem, a system has to represent the traffic on its scale. Hence, estimating the travel speed at a specific time and affording a solution based on reliable traffic data. Accordingly, the passengers are served better. This work contributes to the study by solving the ODT problem in cities with a massive multi-agent system that considers historical traffic data and unpredictable events disrupting the typical traffic. We evaluate the proposed approach by experiments with instances based on actual data for a city in the north of Lebanon. The results reveal that the quality of service increases when the stochastic time-dependent travel speed is considered. 50% to 100% of affected clients by an unpredictable event are satisfied when this event is considered by the system.
