The progress of sensor technology proposes today several types of weigh-in-motion systems, which have been tested for their efficiency, accuracy and cost-effectiveness. Technologies of piezoelectric systems, capacitive mats, bending plates and load cells are used for a number of applications comprising traffic data collection, weigh station enforcement, bridge and toll control systems, truck safety advisory systems and environmental systems. This research explores the potential applications of the available WIM sensor technologies with respect to their technological characteristics and proposes a framework for their exploitation within an integrated information system for the efficient management of road infrastructure. The design of an efficient information flow developed in parallel to the vehicle traffic flow, where information collected at the WIM stations is transferred automatically to the local and central information hubs for -simple or advanced- real-time processing and consequent dissemination of the information, is the key component for the optimum exploitation of weigh-in-motion infrastructure.
