The modelling is the main method of research in many fields of knowledge and a science-based assessment method of the characteristics of complex systems, transport complex systems, to support decision-making in various areas of activity. The author proposes the use cases of the simulation modelling in the transportation hub operation and the planning of short-/medium- and long-term development of transportation hub, as well as the software selection criteria for the simulation of passenger flows at the micro-level.

The authors consider the liquid cargo transverse dynamics at the swaying oscillations. In the case where the tank car carries the liquid load, the car body oscillations directly affect the liquid inside the tank boiler, the liquid affects the boiler walls, and it affects the overall transverse dynamics of the car.

One of the most characteristic features of perishable goods transportation is the transportation seasonality phenomenon. The article presents the parameters for the seasonality intensity evaluation of the perishable goods, the methodology for determining the duration of the seasonal traffic peak and the model the total profit determination of the perishable freight carrier throughout the season.

The paper presents the calculations determining the capacity of the bridge-tunnel. The construction of the bridge-tunnel allows ensuring planning and organization of loading and unloading operations in a given period with a minimum cost of the bridge-tunnel building, its maximum loading in the navigation period in the conditions of the Far North.

The use of "barrier groups" of cars is considered to ensure the marshalling process safety - to prevent the rolling stock from going beyond the effective length of the hump yard tracks. The authors have developed a method for determining the holding capacity and the value of the "barrier group" using the energy conservation law and have investigated the main factors influencing the value and norms of "barrier groups" anchoring.

It is known that when modelling the train movement process detailing gives more accurate results of traction calculations. The "Traction Rolling Stock" chair developed an algorithm based on the Bellman's principle of optimality, without using Lagrange multipliers, even taking into account the train running time.

This investigation develops an approach based on achieving zero injury rates for the entire occupational safety system in the transport industry. To determine the values of characteristics responsible for the representation and implementation of each of the seven basic rules of the concept under consideration, it is proposed to present the final target function as a defining ratio.

The article has developed the hygienic and environmental safety requirements for the railway transportation of convicts and detained persons. These kinds of transportation are associated with the manifestation of harmful factors such as the noise, the vibration, the chemical factor, the exposure to microclimatic working, and others.
