Abstract
In October 1994, indicative radar speed measurements were conducted in the Dutch cities of Eindhoven, Apeldoorn and Haarlem, on four arterial road types (See C 3514 (ITRD 873021)). The measured speed variables and the calculated/aggregated speed variables formed the starting points for a number of statistical operations called "homogeneity analysis" which was performed in the present study. The following statistical operations were undertaken on the basic data: a speed homogeneity analysis, a study into homogeneous measurement locations, and the presentation of an indicative speed distribution.
