The car movement on a section of the first brake position of a hump with slowdown at head wind influence is investigated. The calculation of the speed and traveled distance of the car at its movement with slowdown on the considered hump section is executed on the basis of known quantity of brake action time. It is revealed that the impact of wind from side face of the car effects on the car movement on this hump section.

Approaches to computer model construction simulating the selected object operation during the implementation of the dispatching decision are stated. For traffic operators of different level the controlled objects will be various: polygon, section, station. It is recommended to carry out the modeling by means of the detailed modeling system ISTRA and the macromodeling system IMETRA.

Functioning of the tourist market as a complex system with the distributed control is considered, and the existence of the coordinated set of purposeful impacts on its separate elements which collectively lead to a system common goal during the periods of its possible development under certain assumptions is proved.
The comparison of the European design procedure of underground transport structures and the design technique of the Moscow Metro lines is carried out. Basic distinctions in design approaches are marked out. The recommendations on the basis of the European experience of designing, the non-state expert examination of design phases, the typification of the geological environment and the assessment of environmental impact are given.
The article is devoted to studying of opportunities of mathematical support of the problem solution of dynamic loading of structures of transport constructions, boundary-value problems of deformation and the solution of the functional equations.
