TIME SERIES ANALYSIS OF TRAFFIC COUNTS --TRANSPORTATION PLANNING METHODS. PROCEEDINGS OF SEMINAR C HELD AT THE PTRC SUMMER ANNUAL MEETING, BATH UNIVERSITY ENGLAND, 7-11 SEPTEMBER 1987, VOLUME P290

The objective of the paper is to analyse variation in traffic counts. Separate time series models, using the box-jenkins approach, are calibrated, which describe variation in traffic intensities for more than 50 counting stations all over the Netherlands. Differences in the quality of the fits among these models and the sizes of the coefficients are analysed to study the validity of this approach. Manova and discriminant analysis are used to assess differences among the coefficients of these models in order to examine regional variation. A major proportion of the variation in the counts is explained. It is shown that with relative short counting periods predictions can be obtained with a height quality. In addition to this, it is shown that the models can be used to interpolate in order to estimate missing counts. Conclusions about the sampling procedures for selecting new sites and the most efficient time-frame for counting are intended to improve the quality of traffic counts in the netherlands.(a) this paper is presented in an abstract form. For the covering abstract of the seminar see IRRD 816404.
