Automated Overload Enforcement by WIM

Heavy vehicle overloads contribute to premature deterioration of infrastructure and increase road safety concerns and unfair competition between transport modes and operators. Public authorities and road operators must therefore implement an efficient checking system to enforce weights and dimensions at an affordable cost. WIM (Weigh-in-Motion) technologies are widely used for screening overloaded vehicles, and sometime to issue warnings to the violators. However, these systems are mostly not yet approved by the Legal Metrology for automated overload control and fining. With the traffic volume increase, the safety constraints and the downsizing of traffic officer staff, it becomes necessary to introduce automated overload control by WIM. The ongoing Automated Overloads Control (AOC) project, supported by the French Ministry of Transports (DGITM) and carried out by IFSTTAR and CEREMA, aims to demonstrate the feasibility of automated overload enforcement with adapted existing WIM technologies to be certified. The project is carried out in partnership with WIM vendors. Trials have been carried out in the lab and on the large pavement testing facility of IFSTTAR in Nantes. Sorting algorithms will be developed to identify the vehicles weighed within the required tolerances and on-road trials are planned to demonstrate the feasibility of the whole system.
