### Global Assessment  
Currently--not only in Slovakia but also in other states--the assessment of bridge passage for certain routes is used for heavy and oversized transport. This means that if we use 100 transports, 100 assessments of the individual routes are needed, even if they are the same routes or the same vehicles/vehicle combinations used for a number of transports. Roads are full of different types of vehicles/vehicle combinations for which the axle loads and distances of the axles (wheelbases) are important. There were vehicle/vehicle combination parameters analysed for which the routes in relation to heavy and oversized transport in Slovakia were assessed from 1 January 2016 to 31 December 2020. However, the file contained only data on transports with a total mass that exceeded 60 t or with a total width and/or height that exceeded 4.5 m, which means that a high number of transports with a total mass of 60 t and a width and height of 4.5 m were filtered out, and SRA has not registered them by 2021. Nevertheless, during the revision of Technical Conditions TP 103, there was a request from revisers that was accepted by the road traffic authorities to send data from applications for permission for the exclusive use of a road on a monthly basis to the Ministry of Transport and Construction of the Slovak Republic so that the need for more comprehensive analyses and processes of statistical outputs could be met. As well, this would be fundamental for the relevant design of roads and engineering, as well as any constructions or reconstructions of roads. Our analysed data consisted of information on 1859 route assessments for oversized and excessive transport, within which 932 unique vehicles/vehicle combinations were assessed. In Figure 7, we can see the variability in the parameters of vehicles/vehicle combinations used and in Figure 8 in different intervals of mass. Based on the large variance in total mass, vehicles and vehicle combinations were divided into six categories and the numbers of transports assessed, as well as the number of unique vehicles/vehicle combinations within particular categories, were given in Table 3. \begin{table}

Table 3: Division of transports assessed into categories according to total mass. Figure 6: Process diagram of individual bridge assessment. For each interval of mass, a critical vehicle/vehicle combination was created for which all the values of marginal cumulative wheelbases and cumulative masses of axles were given. To apply these combinations into a currently used application for determining the bridge passage method, or to insert the parameters of the critical vehicle/vehicle combination into the application for a special road use permit, it is also necessary to have the partial wheelbases and partial masses of the axles, given that this was used by the global assessment of bridge passage. Transports up to 120 t represented 85% of all the assessed transports in Table 3. A significant part of these transports is the regular transportation of construction equipment. As a model example for the global assessment of bridge passage procedure, a vehicle
