Intelligent Transportation Systems, ITS Poland is an association whose goal is to educate about the benefits of ITS and to create a platform for the exchange of information and experience between government and local government institutions, industry, the service sector, research institutes, universities and other organizations and individuals.
The Professor Wojciech Suchorzewski Award in the category of Best Dissertation in Intelligent Transportation Systems (ITS) is part of the ITS LEADER competition. In 2024, during the 14th edition of the competition, the award in this category went to Agnieszka Socha from the Silesian University of Technology for her work entitled.
“Signal processing in HSWIM (High Speed Weigh in Motion) systems.”
The competition promotes innovative and effective solutions in the field of ITS that aim to improve the quality and safety of transportation.
Summary of work: This paper presents the types of weigh-in-motion (WIM) systems and pressure sensors. Selected factors affecting the accuracy of WIM systems and how the weighing computer processes the signal are described. Selected methods for determining total vehicle weight and wheel pressures were analyzed. Data for the analysis was obtained from the existing WIM system located on the DK44 national road in Mikołów. This station operates on the basis of strain gauge sensors and the iWIM weighing computer. Static measurements made by the Provincial Road Transport Inspectorate and with the help of a LP788 pad scale with higher accuracy were used as reference values. As part of the analysis, calibration functions were determined using data acquired for a group of test vehicles and independently for each vehicle.
