CLARE II, A 3RD GENERATION TRAFFIC CLASSIFICATION TOOL . THIRD INTERNATIONAL CONFERENCE ON BEARING CAPACITY OF ROADS AND AIRFIELDS. PROCEEDINGS, NORWEGIAN INSTITUTE OF TECHNOLOGY, TRONDHEIM, NORWAY, JULY 3-5 1990. VOLUMES 1-2

This paper describes Danish experience with the new traffic monitoring system CLARE II (CLassification and Axle load REgistration system, generation II), which was specified in 1986 by the National Road Laboratory, Denmark. CLARE II classifies vehicles in groups and at the same time determines the E-10 load for these groups. It measures vehicles by means of four sensors (a scale detector, a loop and two axle detectors) built into the road surface. The scale is used to determine the loads on each axle. The axle detectors determine the number of axles. The weight and axle signals determine the vehicle speed. The loop is used to determine the chassis height and vehicle length. The sensors are linked to the CLARE II microcomputer system, which is used to store data about the detected vehicles and to classify them into up to 70 groups. CLARE II is very flexible and reliable and is used interactively by its operator. Several stations using CLARE II have been installed in Denmark, and 20 are expected by late 1992. There has also been work in Denmark on smaller low cost traffic monitoring systems that are not quite as accurate but enable simultaneous measurements at many sites; about 200 of these systems are now used.
