Abstract. 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 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.

“…The video analysis of conflict situations was used for analysis. The basic information about this methodic is presented in [3], where the method is partly describe by its author (Jan Folprecht), and also in [2] or [4]. The results presented in this paper are obtained thanks to financial aid of research project [5] and they are original (next results of this project ware published for example in [6] and [7]).…”

The traffic safety on intersections is influenced by a lot of external factors -for example by inappropriately designed building elements. Inadequate radius of corners, narrow traffic lanes etc. can cause dangerous situations -above all, during passage by large vehicles. The paper describes conflict situations on intersection which are caused by inappropriately designed building elements above mentioned. The paper points out possibility of use of video analysis of conflict situations for monitoring of these phenomena and also necessity of correct verification of passage through intersection by rupture curves. KeywordsIntersection, Conflict Situation, Video Analysis. AbstraktBezpečnost provozu na křižovatkách ovlivňuje řada vnějších faktorů -například nevhodně navržené stavební prvky. Nedostatečné poloměry nároží, úzké jízdní pruhy atp. mohou zapříčinit vznik nebezpečných situací a to především během průjezdu rozměrnými vozidly. Článek popisuje vybrané konfliktní situace na křižovatce, které jsou zapříčiněny výše uvedenými nevhodně navrženými stavebními prvky. Článek poukazuje na možnost využití videoanalýzy konfliktních situací pro sledování těchto jevů a také na nutnost korektního ověření průjezdnosti křižovatky pomocí vlečných křivek. Klíčová slovaKřižovatka, konfliktní situace, videoanalýza.
