Abstract
The object of the study is the production and technological processes of international road transport (PTP IRT) according to the innovative approach and the conceptual idea of technical and technological energy saving in motor transport. Predictive assumptions about the development of the object of study – the realization of the possibilities of operational-simulation and technical-evolutionary method of complex analysis of transport energy efficiency of road trains and production and technological processes of international road transport in the practice of international road transport. In the course of the research the operational-simulation and technical-evolutionary method of complex analysis of transport energy efficiency of road trains and production-technological processes of international road transportations was considered. As an example, the influence of changes in such a design parameter of the road train as the gear ratio of the main transmission of the tractor on its transport energy efficiency, as well as fuel and energy consumption of the road train DAF FT95.360 (Netherlands) in the test trunk operation (at αg=0). It is established that when the value of the gear ratio of the main transmission (Uo) increases, the value of the energy efficiency indicator (Pe) varies from 0.55 to 0.58. The greatest value of energy efficiency is at Uo=2.846. It is determined that when the value of the gear ratio of the main transmission (Uo) increases, the value of the energy consumption indicator (Ac) increases, and the minimum value of 3.2 MJ acquires the value of the gear ratio of the main transmission – 2.846.It was found that when the value of the gear ratio of the main gear (Uo) increases the fuel consumption (Qc) increases and acquires a maximum value of 3496.84 g with the value of the gear ratio of the main gear – 4.39. The minimum value of fuel consumption of 1684.2 g is achieved when the value of the gear ratio of the main transmission 2.846. The results of the study can be used to implement systemic and conceptual innovation management in the field of international road transport.

Summary
Road trains that are used for international freight transport today represent a wide range of automotive equipment, which is constantly updated and which has a number of requirements (resource conservation, environmental friendliness, fuel efficiency, etc.). The existing methods of efficiency analysis and rolling stock selection have a number of shortcomings for solving the problems of organizing international road transport. They do not provide technological and innovative projects of transport processes and do not correspond to the concept of IIOTERS. The reason is that they are based on the calculation schemes of virtual transportation of goods and passengers [3, 4] These schemes take into account intangible meters of transportation results – ton-kilometer or passenger-kilometer [5]. In [6, 7] energy efficiency in maritime transport is considered, while in [8, 9] the authors emphasize the great potential for improving energy efficiency
