In the study of the functioning of various components of transport systems, there is a constant need to solve problems that are similar to mass service systems. The study of transport systems is reliably described in accordance with processes in mass service systems. Studies of the logistics chains of transportation in transport systems were carried out, as in mass service systems (MSS) for various types of input flows and various intensities of system requirements. The implementation of the work process in the MSS is modeled in information technology using a number of random or pseudoral variables. The results of processing processes in transport systems, as in mass service systems can be processed using mathematical statistics methods. For research, a simplified example of outweigns of goods in international transport corridors was used. The basic principles of modeling structural models of transport systems as mass service systems were taken into account. The modeling results in the above example show that it is convenient to create models of transport systems in accordance with the principle of blocks. In addition, each block should have its own working logic, which imitates a certain process or a certain structure of the system. Some of these blocks can be implemented as standard blocks by included in the standard program library. A model of traffic management systems was investigated at the customs point of the International Transport Corridor using the example of the mass service system.
