Abstract

A research and development project began in France, early 1989, on the Weigh-In-Motion (WIM) techniques and devices, under the leadership of the Laboratoire Central des Ponts et Chaussees (LCPC). This paper briefly presents the objectives, organisation and results of this project. The project is involved in the following areas: a) the development of a new WIM station, "HESTIA". This is a modular device with a main card driving the data acquisition and processing and one additional card per traffic lane. Each traffic lane contains 2 sensors which measure the axle loads independently. In this configuration 8 traffic lanes can be measured simultaneously; b) research into the mounting, signal processing, and calibration of the piezo- electric sensor; c) multisensor WIM systems; d) new types of WIM sensors; and e) customer requirements and project evaluation.
