A summary is given of a method developed to measure driver performance. The procedure developed involved the use of specially trained observer-raters with backgrounds in driver education, traffic and psychology to observe drivers in actual traffic situations. Two observer-raters rode with each subject and rated his or her performance in 3 successive runs on a standardized course. Six behavioral environmental traffic situational sequences (BETSS), representative of urban, suburban and freeway traffic, were developed. Ratings were on the suitability or unsuitability (tendency to reduce or increase hazard) of the driver's behavior. Qualitative and quantitative results were obtained. The driver performance measurement procedure showed high inter-and intra-observer agreement, reliability and content validity.
