FEHRL Institutes WIM Initiative (Fiwi)

Since the early 90's, there has been considerable developments in the Weigh-in-Motion (WIM) industry in Europe. ln addition to technical improvements of WIM sensors and WIM systems there have also been parallel developments to focus on applications. At the moment COST323 specifications are the de-facto European standard for WIM systems. WIM sensors in Switzerland must follow the specifications listed in "Kontrolreglement für WIM-Anlagen" and "Spezifikation für Abnahme und periodische Achslastwaagen". Both these documents use the COST 323 as a basis. ln order to update the COST323 standards, a selected number of FEHRL members including Switzerland represented by Empa have initiated this project named FEHRL Institutes WIM initiative or Fiwi. The main focus of this project was to update the COST 323 standards and submit it to become a new European standard for Weigh-in-Motion of Road Vehicles. This prEN is not officially approved yet but the version from January 2Sth, 2010 is included for information in Appendix 1 which was submitted to the European Committee for Standardization, CEN, members for public enquiry. Once a European standard is approved, it is strongly recommended that the Swiss documents listed above be revised. The most important changes are summarized in this report. They include minimum rate of complete registrations, tolerances for axle spacing, environmental and vehicle conditions and minimum test conditions that are required to achieve a particular accuracy class. A major addition is the inclusion of simplified procedures for common users. During the course of this project, the international society for weigh in motion (ISWIM) has been established with its base in Switzerland. The goal of ISWIM is to support advances in and the more widespread use of Weigh-In-Motion technologies and the applications of WIM data. The Fiwi project has prepared several documents addressing research and application of WIM as follows: Application of WIM to pavement design, to bridge design and for direct enforcement. One of the most important applications of WIM is direct enforcement. The Fiwi project has identified different ways that WIM systems may be used for the enforcement of overloading by heavy road vehicles. ln Addition, an overview is given on the advantages and dis-advantages of each of these applications.
