The purpose of the project was to provide the National Highway Traffic Safety Administration (NHTSA) with quantitative visibility data on current model cars which the NHTSA can analyze for a future Notice of Proposed Rulemaking on "Fields of Direct View." Twenty models were measured for the size of "A" pillar obstruction using binocular testing techniques. Monocular measurements were taken from two eye reference points in the forward 180 degrees and in the rear right quadrant of the vehicle using the test procedures described in the contract work statement. In addition, scale drawings were prepared showing the windshield, the viewing area specified in the work statement, and the relationship of this area to the wiper area requirements as specified by FMVSS No. 104, "Windshield Wiping and Washing Systems."
