abstract="A pilot study was used to test equipment, a headlight measurement system, developed for the measurement of light levels from vehicle headlights traveling on highways. Discussed are the locations where a preliminary study concluded that data on actual light levels are needed by drivers for the night driving task, the characteristics of highway sites to be used for data collection, the identification and classification of vehicle and headlight characteristics used for data collection purposes, the preliminary field studies that were performed, and a summary of the field data results from those field studies. It is emphasized that the field study results, though believed reasonable and accurate, are from a very small sample.
