## 1 Introduction and Literature Review
Their suggestions include a strategy for operational planning based on the maximum width needed for a vehicle combination to travel with a turbine's rotor vanes in order to make the route identification easier. This methodology might be used by transport control authorities to promptly determine the possible unusual corridors for road transport. [PERSON] et al. [17] introduced a new concept of traffic operation management in cities on the principle of network division into several areas. The concept transferred information gained into a public map, being further interpreted for drivers to take a detour. The resulting solution provides a practical and valuable system for the reduction of urban traffic congestion. The selection of appropriate routes for special transport was observed by [PERSON] [18], who applied a procedure in which the route had the lowest number of requests possible and the road and bridge load bearing capacity was not exceeded. These model situations considered vehicles with a width and height up to 7 to 8 m and with a mass up to 600 t.  
Concerning the traffic situation in Poland, [PERSON], and [PERSON], a study has been composed on the possibility of increasing the maximum permitted mass of combination vehicles when transporting wood material in Nordic countries. As well, the study took into account the effect of this solution on the economics of transport and ecology. This also relates to the study of [PERSON] and coll., which, besides this, concludes that the load capacity of vehicle combinations transporting wood material significantly fluctuates during the year, and thus, it is impossible, without knowing the issue in detail, to clearly determine how much cargo can be loaded without exceeding the maximum permitted mass [19,20]. To make oversized transport successful, it is necessary to ensure the use of special equipment and trained people, as well as the application of processes that are diametrically different from common road transport. [PERSON] [21], in his article, defines the conditions for oversized load transport, characterizes the basic types of heavy and oversized transport with required papers, and includes a description of the preparation and organisation of such transports. His following article [22] describes the problems relating to the permits and fines used for oversized load transport, and the problems of transport security relating to the fitting techniques for oversized loads in road transport in Poland. Nowadays, as mentioned in the study of [PERSON] and coll., it is crucial to reduce the costs of transport, given that exceeding the maximum permitted masses of vehicles/vehicle combinations can lead to the excessive damaging of the road network. Other factors to consider include the risk of exceeding the maximum permitted masses, which can increase the risk of a technical problem in the vehicle or a hazardous change in its driving performance [23]. Under Slovak conditions, the load capacity of bridges is determined by the procedures defined in Technical Conditions 104--Traffic loads on road bridges and footbridges. Within these requirements, there are five loading schemes established:  
- normal load  
- single axle load  
- exclusive load  
- exceptional load  
- pedestrian load on footways or cycle tracks  
Normal load is set as the maximum permitted mass of a single vehicle at normal load without a limited number and location of vehicles on the bridge. Currently, to determine the value of normal load, a quantity known as the \"mass of the representative vehicle\", which is given in 320 kN, corresponding to 32 --i.e., the maximum permitted mass of a four-axle vehicle. There is also a quantity, known as the \"factor of normal load\", which is used, bearing in mind the ability of bridge construction to transmit the load caused by load model LM1 according to EN 1991-2. Single axle load is set justifiably according to the decision of the designer's project or substitution project, or the administrator of an engineering construction.
