The project will conclude with the introduction of new products: software for the self-calibration of HS-WIM systems, software for monitoring the operation accuracy of HS-WIM station, and guidelines for calibration and self-calibration procedures.
The innovation of the project lies in the study of the vehicle-sensor-pavement interaction and the impact of variable mechanical properties of the pavement on the axle load measurement error, which has not been previously researched. The goal is to improve the accuracy of HS-WIM systems from class B+ to A according to the COST classification. The software will include real-time assessment of the axle load spectrum, correction of loads due to pavement deflections and the dynamics of vehicle movement. It will also provide a significant competitive advantage to companies that implement it and enable effective enforcement of regulations, similar to the network of speed cameras. This will contribute to reducing the number of overloaded vehicles and extending the lifespan of road pavements.
The second product of the project, guidelines for road administration, will enhance the COST 323 specification by introducing procedures for assessing the quality of measurement data and self-calibration. This documentation and the dedicated software will serve to evaluate and verify the accuracy of HS-WIM systems, which is currently not available to road administration.
