Abstract
In June 1996, a trial of four portable WIM (weigh-in-motion) systems was performed on a heavily trafficked highway near Trappes. France. This site was equipped with a multiple sensor (MS-WIM) array consisting of 24 piezoceramic strip sensors built in the road at non-uniform spacing. Within three days, 116 runs were made with two pre-weighed test vehicles. Moreover 92 trucks in the traffic flow were stopped randomly and statically weighed on a weighing area upstream of the test site. They were used to check the accuracy of the MS-WIM and the four portable WIM systems, using the criteria of the draft European WIM Specifications. Furthermore, the axle loads and gross weights of almost 4,000 trucks were recorded in the traffic flow by the MS-WIM system. This large sample of data was used as a reference to assess the accuracy of the portable WIM systems.
