## 1 Introduction and Literature Review
For single axle load, a load model 2 (LM2) is used according to article 4.3.3 of EN 1991-2. Exclusive load is set as a maximum permitted mass of a single vehicle on the bridge. A vehicle model for exclusive load corresponds to the class of special vehicles 900/150 according to EN 1991-2, article A.2 part (1). The notation 900/150 of a special vehicle means that the total weight of this vehicle is 900 kN, composing of 6 axle-lines of 150 kN with partial 1.5 m wheelbases. Exceptional load in Slovakia is set as an instantaneous maximum weight of a special vehicle transporting abnormal cargo that can be carried by bridges under the defined conditions for bridge passage. In EN 1991-2/NA1, these conditions are specified for travelling at a speed of 5 km/h, fully excluding other transport in optimum trace with a deviation of \(\pm\)0.30 m. As a recommended load model for exceptional load, a vehicle with notation 3000/240 composed of 12 axle-lines of 240 kN and one axle-line of 120 kN is used, and the distance between axles is 1.5 m. The width of a load model is 4.5 m.  
Abroad, there are different load models set for exceptional load. In Austria, there is a model of notation 3000/200 used, i.e., 15 axle-lines of 200 kN with total vehicle weight of 3000 kN, and, in the Czech Republic, there are three different load models used. Concerning highways, motorways, and special roads, load models with notation 3000/240 and travelling at a maximum speed of 5 km/h, excluding other kinds of transport, as well as 1800/20 travelling at a maximum speed of 70 km/h, excluding other kinds of transport, with a weight exceeding 5 kN are permitted. Again, concerning the 1 st and 2 nd class roads, there is a load model of notation 1800/200 with a maximum speed of 70 km/h used, fully excluding other kinds of transport. Load model 900/150 with a maximum speed of 70 km/h is used, while excluding other kinds of transport. Another scientific paper from [PERSON] et al. [24] focuses on the transport of oversized cargo from the urban road network's point of view. The authors analyse the transport of oversized cargo from the perspective of sustainable transport infrastructure in cities. The research results serve as a source for technical conditions that include procedures and technical recommendations in the Czech Republic, bearing in mind a sustainable, safe, and economical transport infrastructure. The authors analysed the results for the determination of parameters to ensure the passage of oversized cargo on roads. Video analysis, GPS devices, drones, modelling, and simulations were used for the analyses of the vehicle routes. This research deals with the issue of the transport of excessive and oversized cargo from the point of view of determining the parameters for roads. The authors also proposed technical recommendations for roundabouts passing, such as modifying the roundabout in the opposite direction, relocating the location of the poles, and increasing the rigidity of the structure of the dividing islands. This research was mainly focused on transport in cities; therefore, no analyses of bridge passing were proposed. [PERSON] et al. [25], in their article, focus on the analysis and discussion of the values in relation to the dimensions, axle loads, and masses intended for road vehicles. The authors debate via comparative analysis which standard would be the most suitable for the real needs of road transport, as well as the requirements of road equipment within the country and abroad. They compare five totally different countries/continents with different legislations. These are China, Japan, Europe, the United States, and Australia. The comparison includes the width of the traffic lanes and the maximum permitted width of vehicle combinations according to their composition and maximum permitted heights. The comparison of the maximum permitted masses included the axle load at a given number of axles and the total weight.
