Lane change and merge maneuvers represent approximately 20% of heavy truck crashes, resulting in loss of life and property damage. Tests were performed to determine the feasibility of developing an Enhanced Camera/Video Imaging System (E-C/VIS) to provide heavy-vehicle drivers with better awareness of their vehicle’s position in relation to other vehicles on the roadway (situation awareness). It is well known that large blind spots currently exist in these areas. A previous phase of this program measured the field of view requirements for heavy trucks, resulting in an improved understanding of mirror performance and recommendations for the design of a camera based indirect viewing system. With indirect viewing requirements understood, the goal of the present research was to extend the operating envelope of a conventional video implementation of the requirements to nighttime and inclement weather conditions. A threechannel system was envisioned in which there would be a camera at each front fender of the tractor looking backward along the sides of the heavy vehicle. The third channel would be aimed rearward from the back of the trailer. Once developed, the three-channel system was tested in static and dynamic driving environments and it was found to work well in the nighttime and inclement weather environments, including various street lighting conditions.
