Abstract:
This study presents a novel, open-source simulation platform designed for on-demand ride service operations. Capable of modeling the complex behaviors and movements of diverse agents—including drivers and passengers—on real-world transportation networks, the platform serves as a robust testbed for operational research. We validate the simulator's efficiency and effectiveness through extensive experiments using real-world datasets. Furthermore, we introduce a suite of AI-driven optimization algorithms, including reinforcement learning approaches, to address critical challenges in on-demand ride services, specifically order matching, idle vehicle repositioning, and dynamic pricing.
