Weigh-in-motion (WIM) technology provides unique way to inform transportation departments and toll operators about heavy vehicle usage on roadways and enables them making more informed infrastructure decisions. In recent years, WIM technology has attracted attention from transportation infrastructure managers and law enforcers across the globe as means for high-speed direct enforcement that could be used to leverage instant fines against overloaded trucks.
According to Traffic Technology International Magazine, high-speed direct enforcement, governed by an international standard, is seen by many as the Holy Grail of weigh-in-motion (WIM). With this new application of WIM on the horizon, traffic authorities must carefully weigh the pros and cons.
ARA experts help federal and state highway clients to develop and implement traffic monitoring directives, standards, and practices to improve efficiency and accuracy in traffic data collection. ARA led the development of a comprehensive WIM guide and training videos for the FHWA Office of Highway Policy and Information, and we have worked with several states to establish, enhance, or modify their WIM programs. Dr. Olga Selezneva, an ARA principal engineer, recently spoke to the Traffic Technology International Magazine about potential benefits and concerns surrounding the adoption of high-speed direct-enforcement WIM.

Dr. Selezneva has contributed professionally to the development of an updated international standard for Automatic Instruments for Weighing Road Vehicles In Motion And Measuring Axle Loads, OIML R 134 to include use of Weigh-In-Motion technology for pre-selection and direct enforcement. She serves as a board member for the International Society for Weigh-in-Motion and is an Editor-in-Charge for the WIM Practitioner’s Guide international publication series. Dr. Selezneva is frequently invited to present at the international webinars, workshops, and conferences on WIM.
