As part of an attempt to calculate accident rates for different vehicle types on various kinds of roads, it was necessary to determine the percentage of each vehicle type in the traffic stream for each type road. This was accomplished by summarizing Kentucky's Vehicle Classification File. The procedure used in summarizing the file and the results of the summary are presented in this report. Vehicle distributions are reported by number of lanes, by functional classification, by administrative classification, by federal-aid system, by hour of day, by day of week, and by month of year. It is believed this report provides the most extensive and accurate data currently available on vehicle type distributions in Kentucky.
