The article presents a comparison of three devices and two methods that are used to count traffic flow. All measurements were carried out at a roundabout in Ostrava, where the following devices were used: Viacount II, Icoms TSM-SA, and Nu-Metrics NC-200 traffic analyzers. The methods of manual counting of vehicles and of counting vehicles based on video footage were used. The article also provides a comparison of the results obtained, namely in terms of traffic intensity, and of the
more » ... of the measurements of the length and speed of vehicles. Further, we evaluate the results and explore the deviations from reality and the reasons why they occur. The article concludes with the recommended procedure designed to eliminate the identified problems, in order to ensure the most accurate results, with no significant deviations.
