Abstract
Overloaded heavy-goods vehicles result in road infrastructure life-time reduction, market distortion and road safety reduction. Analysis of the motivations for overloading showed that competition serves as a strong motivation for companies to overload. The currently extremely low chance on being checked should be increased, to have a violation deterring effect. In the research, four weight enforcement strategies are designed, in which both compliance stimulating and violation deterring enforcement measures are strategically combined. It is concluded that a strategy in which On-Board Weighing is deployed for automated enforcement is expected to result in the largest reduction of overloaded heavy-goods vehicle movements. The efficiency of this strategy, expressed in enforcement costs per sanctionable overloaded heavy-goods vehicle detection, is relatively high compared to non-automated enforcement strategies. Future research should be aimed at defining the optimal subjective probability of being checked for various groups of violators.
