Abstract:There are numerous applications of the Autonomous Maintenance Technology (AMT) that have yet to be fully utilized or widely shared. There are many slow-moving operations conducted by Departments of Transportation (DOTs) with an attenuator (e.g., work zone set up, operations, take down, repairs, mowing, sweeping), platooning of two or more vehicles either directly in-line or with lateral offsets (e.g., snow removal), and roadside infrastructure (e.g., sensors, data architecture) that supports maintenance operations; all of which could benefit from autonomous or smart technologies. Moreover, there has been significant momentum recently by research institutions, DOTs at various levels, and equipment manufacturers to develop autonomous transportation technologies. However, these efforts are often done in isolation of each other, and to best make use of the technology and applications available, it is crucial to fully evaluate and synthesize what technology has been and plans to be deployed. The objective of this research project was to review the literature and subject matter experts to identify (1) DOT operations that would qualify for AMT applications and (2) summarize applications of autonomous technology in maintenance operations that are occurring worldwide. These results show that: 1) autonomous technology in mobile and slow moving operations to date, although still preliminary, have targeted truck attenuators, traffic cone placement/retrieval, sweeping, mowing, pothole repair, and debris removal; 2) advancements have focused on using intelligent transportation systems (ITS), connected vehicles, and data management to create smart work zones, improve worker safety, and communicate to individual drivers through in-vehicle systems; and 3) automation of snowplows and road closures present as a near-term deployable solution.
