Summary
This report establishes revised final performance specifications for Camera/Video Imaging Systems (C/VISs) installed on heavy vehicles, including tractors, straight trucks, and tractor-trailer combinations. The research, conducted by the Virginia Tech Transportation Institute for the National Highway Traffic Safety Administration and the Federal Motor Carrier Safety Administration, aims to standardize the development of viable C/VISs to improve driver visibility and operational efficiency. The specifications are derived from a comprehensive analysis of driver needs, human factors, current and future video technology, systems analyses, focus groups, preliminary tests, and formal on-road tests. The document categorizes C/VISs into two distinct classes: "surrogates," which replace essential side mirrors, and "enhancements," which provide additional views or replace non-essential mirrors. The specifications are structured into three parts: general requirements, detailed specifications for specific concepts, and common technical standards. Surrogates are subject to stringent safety requirements because their failure renders the vehicle unsafe to drive; thus, they must include backup optical mirrors and provide images with true size and perspective to facilitate accurate distance and speed judgment. Monitors for surrogates must be placed at the A-pillars to minimize blind spots and allow easy transition for drivers accustomed to conventional mirrors. Enhancements have less rigorous requirements but must provide comprehensive views with minimal distortion, with monitors mounted in positions that do not encroach on the driver’s direct field of view. General camera requirements emphasize ruggedness, weatherproofing, immunity to glare and vibration, and the ability to operate across wide ranges of lighting conditions. The report specifies that color imagery is preferred for object identification, while monochrome may be used for higher resolution or night visibility. The report details specifications for two surrogate concepts—Left and Right Flat (West Coast) Mirror Surrogates and Convex Left and Right-Side Mirror Surrogates—and nine enhancement concepts, including front blind-spot, side blind-spot, backing, merge/re-merge, and trailer rear-view systems. Specific technical parameters are defined for each concept, including camera field of view, mounting locations, monitor sizes, and image presentation modes (e.g., reversed scan for surrogates to mimic mirror reflection). For instance, flat mirror surrogates require narrow field-of-view cameras mounted on the front fenders with monitors at the A-pillars, necessitating rigorous vibration isolation due to the sensitivity of narrow lenses. The report also mandates that C/VISs be activated only when needed to reduce driver distraction and that systems be designed to withstand the severe environmental conditions of heavy vehicle operation, including vibration, shock, and electromagnetic interference. The significance of this report lies in its provision of a standardized framework for the implementation of C/VISs in the heavy vehicle industry. By codifying best practices and technical requirements, the specifications aim to ensure feasible and uniform deployment of these systems, thereby enhancing safety by reducing blind spots and improving situational awareness. The document serves as a culmination of extensive research, offering manufacturers clear guidelines for developing systems that are both technically robust and ergonomically sound. Adherence to these specifications is expected to result in more efficient driver tasks and improved safety outcomes, while deviations require scientific justification. The report complements a companion document that provides the background research and justification for these specifications.
Key finding
The report establishes specific performance specifications for camera/video imaging systems on heavy vehicles, dividing them into surrogates that replace essential mirrors and enhancements that provide additional views, with detailed requirements for field of view, monitor placement, and vibration immunity derived from on-road tests and human factors analysis.
