The research involved strain gauges which are used for measuring the weight of vehicles, inductive loops, as well as piezoelectric sensors used, inter alia, to detect twin wheels and to determine where a vehicle passes through a station. Since the designers intend the station to be able to implement the direct enforcement function, the selection of runs deviating from the normative ones constitutes an important issue for the assessment of the measurement reliability. The study considered the location of the trajectory of the runs, the dynamics (acceleration\/braking) and the trajectory changes. The change in the amplitude and the value of the signal recorded by the strain gauges as a function of the location (position) of the contact between sensor and tires is a noteworthy observation which indicates the need to monitor this parameter in automatic WIM systems. Other tests also demonstrated the influence of the analysed driving parameters on the recorded results. However, by equipping the WIM station with a set of duplicate strain gauges, the measurement errors of the gross weight and axle loads are normally within the accuracy limits of class A(5) stations. Only in the case of accelerating\/decelerating, does the error in measuring the load of a single axle reach several per cent.<\/jats:p>","DOI":"10.3390\/s21237895","type":"journal-article","created":{"date-parts":[[2021,12,1]],"date-time":"2021-12-01T01:45:02Z","timestamp":1638323102000},"page":"7895","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Influence of Trajectory and Dynamics of Vehicle Motion on Signal Patterns in the WIM System"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7215-6843","authenticated-orcid":false,"given":"Artur","family":"Rygu\u0142a","sequence":"first","affiliation":[{"name":"Department of Transport, Faculty of Management and Transport, University of Bielsko-Biala, Willowa 2, 43-300 Bielsko-Bia\u0142a, Poland"}]},{"given":"Andrzej","family":"Maczy\u0144ski","sequence":"additional","affiliation":[{"name":"Department of Transport, Faculty of Management and Transport, University of Bielsko-Biala, Willowa 2, 43-300 Bielsko-Bia\u0142a, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0973-1734","authenticated-orcid":false,"given":"Krzysztof","family":"Brzozowski","sequence":"additional","affiliation":[{"name":"Department of Transport, Faculty of Management and Transport, University of Bielsko-Biala, Willowa 2, 43-300 Bielsko-Bia\u0142a, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2969-7054","authenticated-orcid":false,"given":"Marcin","family":"Grygierek","sequence":"additional","affiliation":[{"name":"Department of Geotechnics and Roads, Faculty of Civil Engineering, Silesian University of Technology, Akademicka 5, 44-100 Gliwice, Poland"}]},{"given":"Aleksander","family":"Konior","sequence":"additional","affiliation":[{"name":"APM PRO, Barska 70, 43-300 Bielsko-Bia\u0142a, Poland"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,26]]},"reference":[{"key":"ref_1","first-page":"266","article-title":"Analysis and prediction of vehicles speed in free-flow traffic","volume":"22","author":"Brzozowski","year":"2021","journal-title":"Transp.
