The determination for a critical vehicle combination can be used in any country, but the global assessment of bridges must be in line with the national technical specifications for the load rating of bridges e.g., according to the different national annexes of EN 1991-2: Eurocode 1 and different national bridge transit modes. Contributions of the global assessment of routes can be divided into three categories depending on the party affected:  
* contribution for SRA, Road Databank--possibility to make a global assessment for critical vehicles within selected intervals of mass;
* contribution for the haulier--possibility to apply for a global assessment for selected vehicles, group of vehicles, whole fleet, or several numbers of wheelbases when using vehicles with changeable wheelbases;
* contribution for armed forces and armed security forces--assessment for a critical vehicle or for selected fleet on a one-time basis without assessing each route individually. Besides the above-mentioned contributions, the mobile application can be extended to other fields when using suitable software. The application could be a part of the control systems within road transport if the data provided for hauliers were sent to the control authorities as well. When interconnecting the application with GNSS equipment with the option of route recording, the observance of conditions given in the permission for special road use in relation to oversized and excessive transport could be controlled or used in the case of their breach (breach of determined time, departure from the route determined, or breach the speed determined for bridge passage). The application can also serve for monitoring vehicles in real time for their movements, which would mean that the sender, receiver, or other participant will be informed on the location of the cargo. When interconnecting the application with a system of dynamic weighing, it is possible to verify whether the total mass of a vehicle/vehicle combination is identical with the mass given in the permission for special road use. All these additional usages can be applied only if the global assessment of passage performed by using navigational applications will be classified as mandatory. The question is which authority shall perform the global assessment. In Slovakia, the data are processed by SRA, however, publicly available data on bridges are updated on an annual basis, and data of the conditions on 1 January is releasedlater, during the course of the second quarter of the year in question. The released data are often incomplete, causing problems in our assessment as well, and it was necessary to ask for one or more databases from road infrastructure administrators. The research outputs support the implementation of information technologies, digitalization, and electronic communication into the process of oversized and excessive load transport, thereby aiming to preserve the road engineering constructions when breaching the procedures of the given permission for abnormal transport. In the future, it is possible to create the right conditions for online monitoring of all oversized and excessive transports in all the Member States in the EU and to contribute to the protection of road infrastructure, which is partially constructed through the EU Structural Funds, as well as be used in traffic management as a part of smart transport systems.
