Abstract

Systemic traffic count on the Croatian road network hasbeen carried out for more than three decades in different ways. During this period a large number of automatic traffic counters have been installed, and they operate on different principles.The traffic count has been analyzed from the aspect of vehicle classification. The count results can be only partly compared since they yield different structures of traffic flows. Special analysis refers to the classification of vehicles by automatic traffic counters. During the research, a database has been formed with physical elements of vehicles of over five thousand vehicle types. The research results prove that the vehicle length only is not sufficient for the classification of vehicles, the way it is used in the present automatic traffic counts, but rather the number of axles, the wheelbase as well as the front and rear overhangs need to be considered as well. Therefore, the detector system should apply also a detector of axles. The results have been presented that were obtained as part of the program TEST- Technological, research, development project supported by the Ministry of Science, Education and Sport.
