The project WAVE, a transport research and development project in the 4th Framework Programme of the European Commission, on weighing in motion of road vehicles, is being wound down after two and a half years of steady work. Thanks to fruitful co-operation among the partners, and the complementary contributions of the various participating organisations, significant scientific and technical progress has been made and very many results established. New theories, models, algorithms, and procedures have been generated, prototypes built, and field tests performed. New prospects have been opened up in weighing by multiple sensors and by instrumented bridges; an innovative technology bas been developed using optical fibres and optronics, and there have been significant advances in the calibration of the systems and in the quality and management of weigh-in-motion data. Experiments on road fitted with sensors and on instrumented bridges have yielded precious qualitative information on the durability, performance, and precision of many types of weigh-in-motion systems and precision of many types of weigh-in-motion systems, especially in cold climates. The first part of this volume of proceedings (sessions 1 to 4) presents the advances and fallout of the project, with special emphasis on users' expectations, and the second part (sessions 5 to 8) gives the scientific and technical results in more detail.

Straight Motion of Road Vehicles explores the straight motion of road vehicles with particular focus on the role played by tires, vehicle suspensions, and road cross slope. The authors consider vehicles currently in production as well as automated vehicles, which are likely to become more prevalent in the future. This work will lead to the production of safer, smarter, and more comfortable vehicles, enabling engineering solutions for vehicles that naturally run straight ahead, saving fuel and minimizing tire wear.

Weigh-in-motion (WIM) is a process of measuring the dynamic tire forces of a moving vehicle and estimating the corresponding tire loads of the static vehicle. This collection of lectures from the International Conference on Weigh-in-Motion details applications such as: collection of statistical traffic data, support of commercial vehicle enforcement, roadway and bridge cost allocation, and traffic management.

This report identifies potential improvements in terms of more effective safety and environmental regulation for trucks, backed by better systems of enforcement, and identifies opportunities for greater efficiency and higher productivity.
