Abstract The energy load of braking mechanisms of car wheels under tests І and ІІ is reviewed. The computer simulation methods of the heating processes in disk brake mechanisms is considered. The comparative analysis of tem-perature modes of ventilated and non-ventilated bus disk brakes under cyclical (type І) and pro-longed (type ІІ) trials is cavried on using results of simulation.
Keywords disk brake, heating model, temperature mode.
Abstract The currency of cooperative highway intelligent transport systems deployment and main ITS solutions in this field are analyzed. The choice of key technologies of intelligent transport cooperative systems is made.
Abstract This paper presents the development results of a unified electromechanical unit of vehicle's transmission with individual wheel drive. The results of practical implementation and bench testing of this system are examined.
Keywords electric drive, wheel set, traction system, experimental model, vehicle.
Abstract In the article definitions the structure of modern continuously variator, equipped with variable pitch’s chain of propelling type and the application of this mechanism method for heavy load transmission.
Abstract The study deals with a functioning of a snow-melting station as a queuing system. In a model construction there were used distributions of time, needed for tracks to pass different stages of snow utilization. On the example of the created model it’s suggested to analyze the changes in the system's productivity with the varied intensity of the orders.
Keywords snow utilization, snow-melting station, queuing system, modeling algorithm, histogram of time characteristics distribution.
Abstract In the article we have analyzed the workability of a road-roller spin with a flexible shell. We also calculated the contact problem of interaction of the shell spin surface with the compressed material.
Abstract A theoretical study on longitudinal vibration of rod, laden with fluid, which may cause cavitation. The possibility of trigger mode in the system “radiator – liquid” was shown. Detail of pulsation cavitation phenomena in the stepped change of amplitude of exciting force are examined.
Keywords oscillations, Q-factor, cavitation, sonic pressure.
Abstract The article gives a brief overview of the capabilities of modern equipment for the treatment of process fluids and oils, suggested ways to improve the technique of the calculation and the results of the technical and economic benefits when used to repair the installation of operational properties of hydraulic fluids hydraulic RBM.
Abstract The article considers the differences of such concepts as "image", "brand" and "reputation" in the context of a university. The author is concerned about the match of the image model chosen by a university and the methods of building this model in the modern higher edu-cation practice in Russia.
Keywords university image, university brand, image model, applicant, student, graduate.
Abstract In this paper it is described a method of getting and processing of data about change of a dynamic dimension between vehicles and other parameters of the traffic flow. Software which allows to synchronize movement, to provide observance of safety requirements and comfort of each participant is developed.
Keywords traffic, smartphone, video stream, client, server.

Abstract The questions of determining the parameters of traffic on sections of the road network of the city-based navigational information processing controlled navigation system based supervisory control equipment GLONASS / GPS. In the developed approach is formulated theoretically and experimentally prove the hypothesis sufficiently strong statistical relationship between the average speed of passenger vehicles and an average speed of vehicles traveling on separate lanes of the road.
Keywords urban passenger transport, laminar flow, the spatial model, the navigation data.
Abstract The paper contains functional and physical architecture of on-board telematics unit development, which provides unified interaction between telematics systems and the entire range of standard on-board electronic equipment.
Keywords Intelligent Transport System, vehicle to vehicle interconnection, on-board telematics systems
Abstract In this paper it is resulted the argument of necessity and prerequisites for the development of vehicles clustering. It is done for the purpose of their account and adjustment to the design load. The vehicle identification scale to determine their characteristics on traffic density and constitution is offered and gained a subs-tantiation.
Keywords traffic density and constitution, coercion factors, clustering of vehicles.
Abstract The article presents results of research on the hydraulic interactions of dual bridges. Empirical formulas for calculating the first and second critical distances between bridges, when backwaters in front of the upstream bridge is the highest, and when the downstream bridge has no effects on the upstream bridge, as well as for predicting the characteristic backwaters produced by dual bridges.
Abstract In the article there are some data about Cargo automobile park conditions, roads of international cargo transportation in Kazakhstan. Possibilities of using regional transport and goods in transit in Kazakhstan are considered. Special methods are given to choose forms of international and transit transportation with using local motor transport.
Keywords regions, motor transport, transit, conveyances, consumer.
