The article puts forward a new type of culverts in roads. Main motive behind the construction of the new type of culverts is presented and examined: considerable height of road-beds at their construction locations and, as a result, unreasonably high road embankments. Snow drifts at roads and possible protection means are also examined. A report on theoretical analysis of the reasons of snow drifts experimental study with road models is included. The model showed low and high drifts blowing at different speeds at roads with and without embankments and with and without a snow-retaining barrier. All experiments were first conducted without cars on the traffic-bearing surface of the road, then with cars. Recommendations regarding road protection against snow are given.

The paper examines the problem of snow-drafts on roads and ways of mitigating them. The results of theoretical analyses of development of snow-drafts and experimental investigations with road models are presented. Authors examined low and high blowing snows with different wind velocities, roads with road bed at terrain elevation and situated on an embankment, with and without snow protective facilities and with variable amount of traffic. Based on the conducted analyses a set of recommendations for snow protection of roads are provided.

Information is provided on the digital platform of the transport complex, on the methods and technologies of transportation in a digital integrated environment that provides transportation. An overview of open works on modeling transport and logistics systems is given. Information about digital twins is given. The possibility of modeling the digital twin of the cargo is considered.
