Summary
This 1996 report by Raytheon E-Systems assesses the feasibility of deploying Advanced Vehicle Control Systems (AVCS) for highway and airport maintenance vehicles. The study argues that while institutional and legal barriers hinder the widespread adoption of Automated Highway Systems (AHS), niche applications in maintenance operations offer a viable path for early deployment. These applications are characterized by controlled environments, substantial user benefits regarding safety and efficiency, and a user base willing to test developmental hardware. The primary focus is on two highway maintenance tasks: autonomous shadow vehicles for work zones and guided snow plows, with secondary consideration given to airport ground vehicle operations. The research methodology combines a review of existing technical prototypes with a survey of attitudes among state Department of Transportation (DOT) maintenance departments. The report analyzes prior AVCS efforts, including Minnesota DOT’s tele-operated Remote Driven Vehicle (RDV), MacLeod Technologies’ laser-guided autonomous shadow vehicle, and Sacramento State University’s prototype utilizing machine vision and Differential GPS (DGPS). For snow removal, the study reviews magnetic guidance systems and heads-up display (HUD) assistance technologies. To gauge industry receptivity, the authors conducted a telephone survey of state DOTs to determine interest levels, perceived benefits, and cost concerns regarding these technologies. The findings indicate that highway maintenance departments are significantly more interested in autonomous shadow vehicles than in guided snow plows, primarily because shadow vehicles are used universally, whereas snow plowing is regional. Respondents cited worker safety and labor cost reduction as primary motivators, with many expressing willingness to test prototypes if capital costs remained reasonable, such as the $20,000 range suggested for retrofit kits. Technical assessments identified DGPS and machine vision as the strongest guidance candidates for shadow vehicles, requiring redundant systems for fail-safe operation. For snow plows, magnetic road tapes and DGPS-based lane departure warnings were identified as feasible, though challenges regarding infrastructure durability and driver distraction remain. Conversely, airport applications for baggage handling and runway snow removal showed little promise for near-term deployment due to strict Federal Aviation Administration regulations, complex traffic patterns, and low tolerance for system failure. The study concludes that highway maintenance operations provide an ideal arena for demonstrating AVCS technical feasibility without the legal complexities associated with public driving. The authors recommend future work focus on detailed cost-benefit analyses for autonomous shadow vehicles in specific operations like lane striping and road sweeping. For guided snow plows, the report suggests defining detailed deployment concepts and test plans. The overarching implication is that engaging highway maintenance departments as partners can accelerate AVCS acceptance and refine system designs in real-world environments.
Key finding
Highway maintenance departments expressed substantial interest in autonomous shadow vehicles for work zone safety, whereas airport operators showed little interest in deploying AVCS for baggage handling or snow removal due to safety and regulatory concerns.
