Abstract
This paper describes a large scale test of six WIM systems and four additional sensors
on an urban roadway in Zürich, Switzerland. Gross weights from some thousands of
statically weighed vehicles were used to determine the levels of accuracy for each
system, with reference to the new draft of the European specification on WIM
(COST323). The accuracy of axle weights was not tested. The WIM sensors, which
included one prototype were tested with the assistance of a recording and processing
device supplied by the organiser. Most systems encountered some problems, failures
and faults, under the carefully controlled conditions of the 30 month test. However,
these were generally solved by the suppliers after some delay.
Statistics are provided on overall levels of accuracy and on trends with season and time.
In addition, a brief history of system malfunctions and failures is provided. Nevertheless
the scope of the conclusions are limited by the traffic conditions and the test plan.
