In this paper, an analytical model is presented to measure the speed of a moving vehicle using an off-the-shelf video camera. The method utilizes the temporal sampling rate of the camera and several intrusion lines in order to estimate the probability density function (PDF) of a vehicle\u2019s speed. The proposed model provides not only an accurate estimate of the speed, but also the possibility of being able to study the performance boundaries with respect to the camera frame rate as well as the placement and number of intrusion lines in advance. This analytical model is verified by comparing its PDF outputs with the results obtained via a simulation of the corresponding movements. In addition, as a proof-of-concept, the proposed model is implemented for a video-based vehicle speed measurement system. The experimental results demonstrate the model\u2019s capability in terms of taking accurate measurements of the speed via a consideration of the temporal sampling rate and lowering the deviation by utilizing more intrusion lines. The analytical model is highly versatile and can be used as the core of various video-based speed measurement systems in transportation and surveillance applications.<\/jats:p>","DOI":"10.3390\/s20010160","type":"journal-article","created":{"date-parts":[[2019,12,27]],"date-time":"2019-12-27T05:37:08Z","timestamp":1577425028000},"page":"160","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Analytical Modeling for a Video-Based Vehicle Speed Measurement Framework"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3707-2780","authenticated-orcid":false,"given":"Mattias","family":"Dahl","sequence":"first","affiliation":[{"name":"Department of Mathematics and Natural Sciences, Blekinge Institute of Technology (BTH), 37179 Karlskrona, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6834-5676","authenticated-orcid":false,"given":"Saleh","family":"Javadi","sequence":"additional","affiliation":[{"name":"Department of Mathematics and Natural Sciences, Blekinge Institute of Technology (BTH), 37435 Karlshamn, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1094","DOI":"10.1109\/TVT.2006.877462","article-title":"Model for Accurate Speed Measurement using Double-Loop Detectors","volume":"55","author":"Ki","year":"2006","journal-title":"IEEE Trans.
