The proposed method for a moving passenger car load estimation is capable of detecting an overweight vehicle, and thus it finds its application in road safety improvement. The weight of a car\u2019s load entering or leaving a considered zone, e.g., industrial facility, a state, etc., is also of concern in many applications, e.g., surveillance. Dedicated vehicle weight-in-motion measurement systems generally use expensive load sensors that also require deep intervention in the road while being installed and also are calibrated only for heavy trucks. In this paper, a vehicle magnetic profile (VMP) is used for defining a load parameter proportional to the passenger vehicle load. The usefulness of the proposed load parameter is experimentally demonstrated in field tests. The sensitivity of the VMP to the load change results from the fact that the higher load decreases the vehicle clearance value which in turn increases the VMP. It is also shown that a slim inductive-loop sensors allows the building of a load estimation system, with a maximum error around 30 kg, which allows approximate determination of the number of passengers in the car. The presented proof of concept extends the functionality of inductive loops, already installed in the road, for acquiring other traffic parameters, e.g., moving vehicle axle-to-axle distance measurement, to road safety and surveillance related applications.<\/jats:p>","DOI":"10.3390\/s23042063","type":"journal-article","created":{"date-parts":[[2023,2,13]],"date-time":"2023-02-13T02:14:11Z","timestamp":1676254451000},"page":"2063","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Load Estimation of Moving Passenger Cars Using Inductive-Loop Technology"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4186-2710","authenticated-orcid":false,"given":"Zbigniew","family":"Marszalek","sequence":"first","affiliation":[{"name":"Department of Measurement and Electronics, AGH University of Science and Technology, 30 Mickiewicz Avenue, 30-059 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3827-8553","authenticated-orcid":false,"given":"Krzysztof","family":"Duda","sequence":"additional","affiliation":[{"name":"Department of Measurement and Electronics, AGH University of Science and Technology, 30 Mickiewicz Avenue, 30-059 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piotr","family":"Piwowar","sequence":"additional","affiliation":[{"name":"Department of Measurement and Electronics, AGH University of Science and Technology, 30 Mickiewicz Avenue, 30-059 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7864-1516","authenticated-orcid":false,"given":"Marek","family":"Stencel","sequence":"additional","affiliation":[{"name":"Department of Measurement and Electronics, AGH University of Science and Technology, 30 Mickiewicz Avenue, 30-059 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tadeusz","family":"Zeglen","sequence":"additional","affiliation":[{"name":"Department of Measurement and Electronics, AGH University of Science and Technology, 30 Mickiewicz Avenue, 30-059 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9409-8007","authenticated-orcid":false,"given":"Jacek","family":"Izydorczyk","sequence":"additional","affiliation":[{"name":"Department of Telecommunications and Teleinformatic, Silesian University of Technology, 16 Akademicka, 44-100 Gliwice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1016\/j.iatssr.2010.06.003","article-title":"Improving Truck Safety: Potential of Weigh-in-Motion Technology","volume":"34","author":"Jacob","year":"2010","journal-title":"IATSS Res."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1413","DOI":"10.1016\/j.trpro.2016.05.214","article-title":"Weigh-in-Motion for Direct Enforcement of Overloaded Commercial Vehicles","volume":"14","author":"Jacob","year":"2016","journal-title":"Transp.
