Abstract

The load transported by road vehicles is subject of concern for the traffic authorities worldwide. The weight excess in vehicles has a direct impact on society, because of the detrimental effect on roads life time. The damaged roads lead to a higher number of accidents and deaths, damage vehicles and cause delays on trips. The technology for the identification of the force exerted by a vehicle on the road is the main factor for controlling the road usage. Measuring instruments have been installed along the roads to monitor the vehicles load and to check the associated parameters established in the national specific legislation. The analysis of reliability of the measuring instruments is very important as the accuracy is relatively different among the instruments used. This work evaluates the reliability of road vehicles weight measuring procedures for the weigh-in-motion system, by a developed model applied to an exploratory research in two weighing stations, using statistical tools, reliability analysis and making use of Monte Carlo method for the uncertainties evaluation. This model is capable of improving the process accuracy contributing for the reduction of damages caused by the weight excess of road vehicles.
