Abstract In this article developed the classification of STV (SINGLE-TRACK VEHICLES) by a large number of parameters, characterizing STV as a separate type of transport with its features and variety. This classification reveals the fullest, and all structures manifold single-track vehicles. Using this classification we can, but more detailed and focused to develop Management System of STV and calculate models of motion.
Abstract In this work some method of definition of support reactions of a static construction is considered by the construction transformation into mechanism with the number of freedom degrees equal to the determinable reactions number. Then the principle of the possible movements. is applied to the equilibrium of this mechanism Thus from the only equation one can get the necessary quantity of support reactions.
Abstract In the article definitions a review of the types and structures of modern continuously variable transmissions (CVT). There are given the shortcomings of existing structures and the advantages of the newly developed designs. CVT different structures are considered, ways of increasing their efficiency are indicated.
Keywords transmissions, transmitting element of V-belt variator, chain variator.
Abstract In article advantages transporting heavy goods with multisupporting platform in comparison with conventional heavy load vehicles are reviewed. Some basic calculation its maneuverability are shown.
Abstract This article describes the tasks of modernization by managing economic entities of the motor transport at the present operation stage of the Russian transport system. Modernization of property management of the haulage company is suggested to implement by using the business cost management methodology (cargo motor transport) and ownership-financial technologies (municipal public transport). The article is written on the research of the scientific-research work in the framework of the Federal target program « scientific and scientific-pedagogical personnel of innovative Russia for 2009-2013».
Keywords modernization, property complex of organizational-economic mechanism of management.
Abstract The paper analyzes the basis building of indirect and direct traffic management subsystems, and to ensure inter-system interaction between them in the formation of a unified integration platform.

Abstract This article focuses on the issues related to the possibility of information exchange in the enterprise, that uses ERP (enterprise recourse planning)-systems and takes part in the integration with the technology of project's lifecycle informational support, by representing a simplified mathematical model of the system.
Keywords ERP-system, virtual enterprise, system of input-output.
Abstract In this article the mathematical model of estimation of automated system of information processing and management with provisioning by the substitution spare elements composition was considered with a given required probability of failure-free operation and required system operation time. Certain method and algorithm were developed to simulate the estimation of system spare elements composition.
Abstract This paper presents a comparative analysis of different methods of designing systems of indirect traffic control. The basic advantages of the design quality of the matrices of correspondence, an algorithm design system of indirect control traffic flows on the basis of qualitative matrices of correspondence describes the sequence of their design.
Keywords management, traffic flow, qualitative matrices of correspondence.
Abstract In this paper the technology is seen as ActivRFID telematic service application, which is a subsystem of Intelligent Transportation Systems. It is also proposed to improve existing methods for positioning a tool to improve the reliability of traffic control.
Abstract The article reviews operation of diaphragm plates at branching of steel ferroconcrete flyover span structures. Maximum loading of various-structure diaphragms resulted in strain which proves that use of two-plane solid-wall and grid-type diaphragms does not improve operation of a branching span structure.
Abstract The paper is devoted to methods of definition of the basic hydrographic characteristics. Recommendations by definition of the area of a catchments basin and lengths of the main water-current are given. New analytical expressions for calculation of the average inclination of the main water-current and for definition of an average inclination of slopes of catchments basin are offered.
Keywords hydrographic characteristics, the area of a catchments basin, inclination of the main water-current, grade of slopes of a catchments basin.
Abstract The approach to relative working capacity indexes of non rigid pavements are observed in the paper. Some of the approaches dont find any application in official design procedures. The comparison of the results gained under various approaches is also resulted. The special attention is given to correlation of operational and equivalent strength coefficients.
Keywords functionality and working capacity of pavements, strength indexes, equivalent strength, level of design reliability.
Abstract The complex approach to management of the engineering data of a highway allows to build efficient control, a coordination and a transparency of decision-making throughout highway life cycle. In article process of the formalized integration of considerable volumes of the specialized diverse engineering data is described. Stage-by-stage integration of the given formalized measuring apparatuses will allow to solve problems of a road economy with specialized federal databases on maintenance of the automated information account of elements of life cycle of road - researches, designing, building, complex diagnostics, certification, inventory, management of a condition of highways.
Keywords the registration of the engineering data, hardware-software system, video monitoring, highways, geoinformation technologies.

Abstract The article deals with the development of formal methods and models for the clustering of physical and mechanical properties of asphalt concrete mixtures as tools for exploratory data analysis to build predictive models of quality asphalt pavement with the use of universal analytical and statistical software. Combination of methods proposed to cluster, discriminant analysis and neural networks to build a classifier based on the results of cluster analysis using data mining ideology, implemented in the package STATISTICA 8.
Keywords ABS, data mining, clustering, exploratory analysis.
Abstract This article describes the use of ash waste in the production of concrete as a filler for mixed binder. The authors proposed process, which yields a new building material with high technical and economic performance through the use of cheap and readily available raw materials. The problems of automating the process of redistribution in order to increase productivity, improve quality and reliability of the units.
Keywords organic-additive mixture of slag, ball mill.
