Abstract:

Forensic Engineering evaluation of visibility related issues in the night driving environment requires the understanding of a range of phenomena, including the human visual system, the nature of light, the measurement of light, and the limitations of human perception. This short paper outlines the pertinent topical areas, and is intended to supplement a more detailed discussion presented at the NAFE meeting in January 2005 in San Diego. Although many important vision concepts are omitted, the Forensic Engineer will gain an appreciation of the fundamental issues. Results of visibility tests on some common items are presented to guide the reader, and to correlate with other data they may encounter in their individual practice. Three cases are discussed, which include the elements of night driving, glare, conspicuity, contrast, and human perception and reaction.
