In a previous paper, Shinar, Mayer and Treat evaluated the reliability and validity of a battery of 17 driving-related vision tests. The present paper reports progress made in the development of these tess towards the establishment of an integrated battery of license branch- oriented driver vision screening tests. In an affort to expedite the testing procedure, the eleven most promising tests of the original 17 were incorporated in a fully automated battery. The tests yield measures of static central visual acuity under conditions of optimal illumination, low levels of illumination, an glare; dynamic visual acuity, visual field, movement thresholds in the central and peripheral fields, and visual search-and-scan ability. Evaluation of the new battery is proceeding in four directions: the reliability of the tests; their validity as predictors of accident involvement; the practicality of the device as a license branch test; and the development of diagnostic and remediation procedures for people who might fail the tests. The results indicate that most of the tests are reliable, insofar as yielding similar results on the test and retest. This is expecially true for subjects who perform well, and less so for subjects who perform poorly, i.e., those who would be candidates for failing the test. /HSRI/
