This document provides revised final performance specifications for Camera/Video Imaging Systems (C/VISs) used in heavy vehicles. The specifications are based on a combination of analyses including driver needs and human factors, current and future video technology, systems analyses, focus groups, preliminary tests, and formal on-road tests. In these specifications C/VISs are divided into two categories: surrogates, which take the place of the essential side mirrors, and enhancements, which are all other applications. The specifications are written in three parts: an introductory section defining terms and stating general requirements, a section providing detailed specifications for two surrogate configuration concepts and nine enhancement concepts, and a section providing additional common detailed specifications. The specifications are intended to serve as a culmination of best approaches and practices for development of viable C/VISs. It is expected that if the specifications are followed, they will result in feasible and reasonably uniform implementation, thereby making the heavy vehicle driver's task more efficient. |
