This article reviews the current weigh-in-motion (WIM) technologies and compares their cost and accuracy. WIM systems allow for the unobtrusive and continuous collection of vehicle weight information, ranging from precise individual weight measurements for each vehicle to aggregate vehicle weight profiles for road sections. The article's objective is to explore thepotential applications of available WIM sensor technologies with respect to their technological characteristics. A framework for their integrationinto the efficient management of road infrastructure is proposed, focusing on design, data requirements, decision support functionality and functional characteristics. The benefits of the integration of WIM applications in appropriate road management information systems are also discussed.
