Abstract
The paper assesses the process of cleaning and highways of the city of Moscow, Moscow Ring Road on the example plot 68…94 km. The shortcomings of existing technology cleaning. As a result of the monitoring cycle for washing machines pavement Moscow Ring Road found that the proportion of working time spent directly on the sink is only 36%. The rest of the 64% is spent on idle run and repeated refilling machines with water during the work shift.

Keywords
cleaning, productivity, technology, monitoring. 

Abstract
The opportunity of expansion of a zone active cavitational erosion is considered at high amplitude to ultrasonic clearing. A way of increase of efficiency of ultrasonic liquid processing.

Keywords

Abstract
The definition of main indicators of technical efficiency of bulldozer, and their dependence on the time cycle are considered. A mathematical model of the duration of cycle time of the bulldozer and its simplification are presented. The influence of the mass of machines on the duration of the cycle is considered.

Keywords
efficiency, bulldozer, the optimal weight, work cycle, work operation, mathematical model, productivity. 

Abstract
A complex of technologies of hardening of steels by the thermo-chemical treatment is presented, which basis on nitriding of steels in low-temperature plasma of electrolyte steams. Processes of hardening of carbon and high-alloyed steels by hydro plasma nitriding, and strengthening of carbon steels by combined technologies including nitriding, carburizing and diffusion metallization by an alloying element (chromium, aluminum, vanadium, titanium, tungsten, cobalt, nickel, molybdenum, niobium), are considered.

Keywords
thermo-chemical treatment, nitriding, low-temperature plasma, metal diffusions, electrolytic conductor. 

Abstract
The article assesses the Standard & Poor's transparency index method. Given results of comparative analysis of the criteria included in these techniques as per their conformity with Russian standards of information disclosure. Held forth the author 's method of index of transparency.

Keywords

Abstract
In article the basic expenses of the enterprise on maintenances and operation of park of cars are considered. The technique of definition of optimum quantity of snowplows for clearing of city territories of snow and ice is analyzed. The questions connected with drop of financial expenses in case of application of a technique of selection of optimum necessary quantity of units of the snow-removing technics for clearing of highways, roads and domestic territories from snow are analysed.

Keywords

Abstract
Consider is the method of improvement of the way of layout of the roadway coverings of lighten type. Suggested is the production techniques, allowing in contact with traditional one, to enhance the strength, durability and life time of the covering. Given are the deepen dances of the wear of covering and life time on the load intensity of the traffic.

Keywords
treatment of surface, roadway covering, bitumen, load intensity, life time. 

Abstract
In the article the technique of managing the operational state of the roads using verbal information expert road sector. Indicates a sub-stantial subjectivity in the approach based solely on the theory of fuzzy sets. To eliminate these shortcomings, we solve the problem of synthesis of the apparatus of fuzzy sets with neural networks. As a result, proposed an objective method of managing operational condition of roads based on fuzzy neural networks. The practical examples of forecasting changes in the operational status of highways.

Keywords
roads, operational status, fuzzy sets, neural networks. 

Abstract
In the following article the outer surroundings monitoring method of automobile industry enterprise which works in the sphere of international automobile transportation is described. The method is based on the cognitive technologies. The monitoring role as the method of automobile transportation informational maintenance mechanism is disclosed.
The automobile transportation surroundings monitoring algorithm is also presented. It is based on the applying of modeling and cognitive analysis methods.

Keywords

Abstract
Significant increase in volumes of traffic in large Russian cities demands reconsideration of general approaches to the formation of efficient transport systems. Search for reserves to enhance the functioning road transport industry of the city lies in increasing the carrying capacity of existing transport infrastructure. Demands are new methodological approaches to justify the selection of separate lanes of urban passenger transport.

Keywords
