Abstract

The author identified the main shortcomings of existing urban transport modes, described a new form of urbanized region - conurbation, refined the concept of «urban mass rapid transit transport» and «innovative transport project», proposed the technique to evaluate external effects of such projects. The need for creation of new types of passenger transport in terms of strategic and socio-economic problems of development of St. Petersburg, including on the basis of magnetic levitation technologies, is substantiated. The purpose of innovation is to significantly improve transport services for the population, reduce time and money expenses to travel, to remove some load on the highway, to reduce environmental pollution.

Abstract

Mathematical modeling of the first intermediate section of a hump yard at the impact on the car of tail wind of small value is presented. The applied method is D'Alembert principle in coordinate form with non-ideal bond. Simple in appearance, analytical formulas were obtained for determining time of car movement at a hump yard, according to the value of which speed of its rolling into the end of the settlement area is determined. It was revealed that the time, during which the car rolling at this section of the hump yard depends on inclination angle, initial speed and acceleration of the car, as well as controlled length of movement.

Abstract

An analysis of road vehicles fleet in the country was conducted, rates of availability of cars for citizens in Russia and abroad were compared, the dynamics of structural formation of consolidated and regional budget due to tax revenues by types of transport was studied. Tax preferences for transport taxwere systematized for categories of transport and taxpayers, attention was also focused on tax requirements for rented vehicles, which do not contribute to reduction of applied tariffs and stimulation of entrepreneurial activity. Foreign taxation experience was generalized at the example of Germany, Ukraine, the USA, Denmark, Japan. Arbitration practice of tax disputes on transport tax was assessed. Proposals for improving regional taxation of vehicles in the interests of the state and taxpayers were formulated.

Abstract

Development of methodological fundamentals of a model of risk management, put forward by the author, focuses on maximal accuracy of identification of specific industrial risks in the corporate units. Requirements to the contents of the model are determined at the example of locomotive complex. The author suggests classification of external and internal risks, as well as an approach towards economic evaluation of risks described in terms of responsibility of each corporate locomotive business unit for direct and implicit damage caused by rail accidents. Criterion is selected, being a part of safety expenses of a company, and not a profit fluctuation.
