Non-myopic Matching and Rebalancing in Large-Scale On-Demand Ride-Pooling Systems Using Simulation-Informed Reinforcement Learning
Ride-pooling services, also known as ride-sharing, shared ride-hailing, or microtransit, offer significant benefits by reducing costs, congestion, and environmental impact. However, current systems often suffer from myopic decision-making, overlooking long-term consequences. This study introduces a novel simulation-informed reinforcement learning (RL) approach to address this limitation in large-scale ride-pooling systems. By extending existing RL frameworks to ride-pooling and embedding a ride-pooling simulation, the proposed method enables non-myopic decision-making for both vehicle-rider matching and idle vehicle rebalancing. Utilizing n-step temporal difference learning on simulated experiences and NYC taxi data, the approach significantly increases service rates (up to 8.4%), reduces passenger wait and in-vehicle times, and can decrease fleet size by over 25% while maintaining performance. Incorporating rebalancing further cuts wait times by up to 27.3% and boosts service rates by 15.1%.
