本文考虑了大规模实时共乘系统的调度,以解决许多城市面临的拥堵问题。目标是用少量车辆为所有客户提供服务(服务保证),同时在乘车时间限制下最大限度地减少等待时间。本文提出了一种端到端的方法,该方法紧密集成了最先进的调度算法,机器学习模型来预测随着时间的推移的区域到区域的需求,以及模型预测控制优化来重新定位闲置车辆。在纽约市使用历史出租车行程的实验表明,这种集成在所有测试案例中将平均等待时间降低了约30%,在高需求区域的最大实例中达到了接近55%。
This paper considers the dispatching of large-scale real-time ride-sharing systems to address congestion issues faced by many cities. The goal is to serve all customers (service guarantees) with a small number of vehicles while minimizing waiting times under constraints on ride duration. This paper proposes an end-to-end approach that tightly integrates a state-of-the-art dispatching algorithm, a machine-learning model to predict zone-to-zone demand over time, and a model predictive control optimization to relocate idle vehicles. Experiments using historic taxi trips in New York City indicate that this integration decreases average waiting times by about 30% over all test cases and reaches close to 55% on the largest instances for high-demand zones.
