VISIBILITY MEASUREMENT TEST (FIELD OF DRIVER VIEW). VOLUME 1
Three replications of measurements were made on a 1979 American Motors Concord, a 1979 Ford Econoline Van, and a 1979 International Harvester F4300 Transtar conventional truck tractor to determine the performance of rearview mirror systems, the angular size of obstructions to the driver's direct field of view, and specified viewing areas through the windshield. The tests were made to determine the accuracy and repeatability of methods for measuring direct and indirect fields of view from motor vehicles as proposed in a new Federal Motor Vehicle Safety Standard (FMVSS) for fields of direct view (Docket 70-7; Notice 5) and a revision to FMVSS 111, Rearview Mirrors (Docket 71-3a; Notice 4). Background and a general description of the testing program are provided, followed by sections documenting the test area, instrumentation, test vehicles, test procedures, calibration, test results, and photographic coverage of the tests. Problems encountered with the test procedures are outlined and improvements suggested. The area of greatest concern was the photographic data from truck convex mirrors.
