Abstract
Engineering and the industry very often produce above-standard products concerning their dimensions and weights. There is often a problem with the transport of these products both within Europe and in subsequent transport all around the world. Because of these reasons, several projects to remedy the situation were implemented in the Czech Republic. The article describes the results of many years of research, which observed ensuring the passage of oversized cargos on roads. Further, the measurements, which were carried out, are presented in this paper − the measurement of an oversized vehicle using Global Positioning System devices, creation and modelling of missing cars in programs to verify the swept path, comparison of created models with the measurement using Global Positioning System devices. Then the results of the implemented researches, the suggested parameters, and modelled cars are used for the suggestion of technical parameters of backbone network of roads. On these roads, the loads are transported. The results are also used for verification of critical points of the route, e.g. problematic places and intersections.

The Czech Republic has a long tradition in engineering and industry
The curves created based on the measurement from the points of the Global Positioning System (GPS) were compared to the swept path of edges of the low-loading trailer of the created vehicle in AutoTURN software
The article describes a part of the results of long-term research, which were conducted to ensure the passage of oversized and excessive cargos on roads in the Czech Republic
Summary
The Czech Republic has a long tradition in engineering and industry. These industries often produce products whose dimensions and weight are considered above standard. The Finnish network of roads for the transport of huge oversized cargo is predefined (Petru & Krivda, 2017) They created sets of standard values and instructions for dimensioning infrastructure of roads in Finland (European Commission Directorate..., 2006; Laitinen, Stenman, Heikkilä, & Väätäjä, 2013; Nyrhinen & Gröndahl, 2007; Setälä, 2003). Within the research the regulations concerning designing of roads were examined, e.g. from Holland (DHV Environment and Transportation, 2005), Germany (Forschungsgesellschaft für Straßen-und..., 2005) and the USA (Transportation Research Board, ..., 2000) None of these regulations set parameters, which are possible to use as a model for the creation of Czech regulation. The result of the projects was the determination of spatial parameters (Tables 3 and 4 containing data and values of radii of corners, heights, widths, vehicles for verification of the passage), which were applied to oversized and excessive cargos on backbone routes
