In smart cities of the future, how to sense, understand, and manage urban-scale vehicular systems, e.g., taxis, in an autonomous fashion (with little or no human intervention) is an essential topic to improve urban mobility efficiency, such as shorter waiting time for passengers, lower cruising mileage for drivers, and higher revenues for vehicular system operators. However, the current management strategies for vehicular systems are mainly based on individual-level data knowledge, ignoring rich information from a fleet perspective. In this project, the investigators design and implement a fleet-oriented management strategy for vehicular systems, which utilizes real-time data from sensors installed in all vehicles to improve the overall performance of the vehicular system. In particular, the investigators aim to improve the taxi system performance by using onboard cameras to detect waiting passengers on streets and share this information with nearby vehicles and dispatch centers to pick up these passengers through a dispatching strategy. The research team will develop a clear understanding of how to design an adaptive autonomous vehicular sensing and dispatching strategy to improve urban mobility efficiency from a fleet-oriented perspective, with potential applications to future fully autonomous fleets. Such an understanding on vehicular sensing and dispatch will improve the quality of the every-day life such as more efficient commute for passengers, and lower energy uses for drivers, and finally improve the environment for the society by low vehicle mileage.This research develops a fleet-oriented sensing and control framework to enable seamlessly integration of historical and real-time data within a fleet for adaptive vehicular sensing, modeling, and control. Specifically, this project studies how to best use spatiotemporally-correlated contextual information (e.g., vehicular mobility, service demand, disruptive events) among vehicles. Although such correlations decay over time and distance, it is possible to enable autonomous vehicular sensing, modeling, and control adaptively based on the following research to develop novel services: (i) reconfigurable fleet-wide coordinated sensing by autonomously learning correlated vehicular interactions; (ii) models of mobility phenomena by collectively interpreting implicit data from different vehicles with a combination of deep learning, structured learning, and attribute-based learning; (iii) designs of robust dispatching strategies with uncertainty sets and receding horizon control frameworks by iteratively considering fleet-wide knowledge to improve mobility efficiency.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在未来的智慧城市中，如何感知、理解和管理城市规模的车辆系统，例如，自动驾驶出租车（很少或没有人为干预）是提高城市交通效率的一个重要课题，例如缩短乘客的等待时间，降低司机的巡航里程，以及提高车辆系统运营商的收入。然而，目前的车辆系统管理策略主要是基于个人层面的数据知识，忽略了丰富的信息，从车队的角度来看。 在该项目中，研究人员设计并实施了一种面向车队的车辆系统管理策略，该策略利用安装在所有车辆上的传感器的实时数据来提高车辆系统的整体性能。特别是，研究人员的目标是通过使用车载摄像头来检测街道上的等候乘客，并与附近的车辆和调度中心共享这些信息，以通过调度策略来接载这些乘客，从而提高出租车系统的性能。研究团队将对如何设计自适应自主车辆传感和调度策略有清晰的认识，以从面向车队的角度提高城市移动效率，并有可能应用于未来的全自动车队。对车辆传感和调度的理解将提高日常生活的质量，例如更有效地为乘客提供通勤，降低驾驶员的能源消耗，并最终通过低车辆里程改善社会环境。本研究开发了一个面向车队的传感和控制框架，能够无缝集成车队内的历史和实时数据，以实现自适应车辆传感，建模，防治的攻坚具体来说，这个项目研究如何最好地使用时空相关的上下文信息（例如，车辆移动性、服务需求、破坏性事件）。虽然这种相关性随着时间和距离而衰减，但是可以基于以下研究自适应地实现自主车辆感测、建模和控制以开发新的服务：（i）通过自主学习相关车辆交互来实现可重构的车队范围的协调感测;（ii）通过结合深度学习共同解释来自不同车辆的隐式数据来建立移动现象模型，该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
