Published: June 2020

Abstract
The development of basic algorithms for processing navigational data in dispatching control systems of road transportation of goods and passengers on specified routes is discussed in this article. Algorithms for processing navigation data with the use of GIS-technologies are described. The features of the “linking” of navigation marks to the zones of control points represented in the spatial model of the route by polygons formed by means of specialized editors of geographic information systems are described. The algorithm of recognition of flights performed on a given route based on the analysis of the actual data on the passage of checkpoints of the route by the vehicle, as well as the algorithm of recognition of liberty mileage is considered in detail. The description of the algorithm for comparing the planned and actual indicators of transport work developed using the theory of sets is presented. A block diagram of an algorithm for a step-by-step evaluation of the results of performing transport work is presented on the basis of the application of the procedure of stepwise narrowing of the set of admissible alternatives.

Abstract
Road Design Manuals propose the procedure for determining the accident rate at modern roundabouts by the probable number of major accident of types on specific sites of a roundabout per year. An assumption is made that the regression equation may not take into account the design features of modern roundabouts, climatic conditions, as well as driving style in the Russian Federation. The paper presents a step-by-step method of the regression equation validation to assess the accident rate at the approaches to the roundabouts on the basis of other statistical methods. The validation involves the statistical evaluation of the sample correlation coefficients between the accident equation and the factors affecting it. Within the work the values included in the equation were non-dimensionalized, necessary assumptions were introduced, and the features of performing correlation analysis in the particular case were analyzed. The procedure proposed enables to determine the reliability of the equation for determining the accident rate at the approaches to a modern roundabout in the conditions of the Russian Federation, taking into account climatic conditions, design features, the state of the existing road transport network, as well as driving style.

Abstract
The article considers changes in requirements for spare parts for maintenance and ongoing repair of urban buses taking into account their mileage from the beginning of operation. The research was carried out with the purpose of development of a technique that would help one to determine coefficients of correction made to specific norms of consumption of spare parts for various age groups of buses on the basis of changes in their failure flow. Correction factors were calculated for the four selected age groups of buses. In addition, the article considers the issue of reducing the annual mileage of the public transit bus while increasing its service lifetime. The methodology was tested on taking LiAZ-529222 and LiAZ-621322 urban buses as an example, operated in Moscow. As a result of the performed calculations, values of coefficients of correcting the consumption of spare parts have been obtained for the considered modifications of buses in each age group.

Published: June 2020

Abstract
The paper considers an integrated approach to the management of the life cycle of the transport and logistics infrastructure, basing on the concept of digital transformation and logistics engineering. The issues of digital transformation of the transport infrastructure are of particular importance in the context of the transition to the concept of Industry 4.0. This implies the existence of new infrastructure requirements, both in terms of costs and from a strategic approach to increasing business productivity, taking into account the sustainability criteria and response time to failure situations. As the basis of a highly efficient integrated TLS, there is a coordinated interaction of enterprises within the stages of the life cycle “design – operation – operational control – check and corrective actions – check of the control system”. New approaches have been recommended that provide highly efficient support for global transport systems, not only through the use of digital technologies, but also logistic engineering methods.

Abstract
The organization of traffic is a complex of engineering and organizational arrangements aimed at maximizing the use of traffic flows opportunities represented by the road geometric parameters and condition. The article deals with an example of using software modeling for creating a digital twin of a complex intersection in Saratov in order to verify the engineering hypotheses concerning the effective transportation planning. The current traffic situation in the PTV VISSIM program is simulated. The transportation planning engineering hypothesis proposed and simulated the solution options of changing the working traffic light duration at the intersection for verifying and widening the carriageway by adding a lane. The analysis of two models options allowed determining the most effective transportation planning measure in a given transport hub of the city with a high level of traffic delays, which is actually the duration change of the working traffic light at the intersection. The software modeling application is confirmed for creating a digital twin complex intersection in Saratov.

Published: June 2020

Abstract
The extensive development of the structures of the automobile-road complex requires optimization of the processes of their integration into the regional and global transport infrastructure. In order to effectively manage unstable traffic flows, automated control systems are developed that use complex algorithms based on the principles of artificial intelligence. The basis of this approach is the concept of transferring the concept of a control object from a generalized or aggregate traffic stream to a separate control element: a separate vehicle, a separate passenger, a separate consignment. The completed management process in the system of the road complex, which meets the current level of development of scientific and technological progress and productive forces, requires the use of digital object-oriented management models based on the creation of a unified communication and computer network for managing information flows as well as the development and application of control models physical objects of movement in the transport network, determining the optimal trajectory of movement of the latter. To form a control system based on object-oriented models, it is necessary to develop specialized analytical methods for multi-criteria evaluation of possible options. It is of fundamental importance that the developed methods can investigate the field of probabilities of changes in informational situations of the environment and are applicable to factors of any degree of uncertainty.

Published: June 2020

Abstract
In order to successfully accomplish the tasks of digitalizing control processes in the road complex integrated into a focused process, new generations of control systems — intelligent control systems – are being actively developed today. Intelligent control systems should be able to independently develop a goal, implement the decision-making process for an action, provide the necessary set of functions to achieve a goal, predict the values of system indicators as a result of actions and compare them with real data, providing feedback in the system and adjusting the control procedure. Currently, the methodological basis for making management decisions in control systems is the concept of scenarios based on the theory of expert assessments. The main disadvantage of this approach is the inability of the system to gradually adapt to changes in input information without completely reworking the structure of the initial requirements. For effective implementation of this task, it is necessary to develop a decision-making methodology in control systems based on formal logical methods of decision theory, namely, analytical methods for obtaining many effective plans, which should allow us to build algorithms that provide optimal solutions when implementing applied management tasks while having minimal information about the conditions of the research object.

Published: June 2020

Abstract
For effectiveness assess of management decisions in modern economic systems, as a rule, single-criterion mathematical models are used, which have several disadvantages. The use of qualitative single economic efficiency criterion for complex production processes comparative evaluation in digital economy leads to a high proportion of subjectivity. Modern complex production, based on intelligent communication technologies, operates in specific information situations context that require the use of adequate mathematical tools for making effective management decisions. In such tasks, effective solution choice depends on external and internal environment state of the system being studied and implies the use a number of methods for solving multi-objective tasks. The main methods used in uncertainty situation cases due to information situation complexity are prior ranking or expert evaluation methods. Naturally, methods based on expert evaluation have significant degree of subjectivity. This disadvantage can be avoided if you solve the problem using scientifically based effectiveness evaluating methods of production processes not by one but by several relevant performance indicators.

Abstract
Wheel tire wear annually takes hundreds of thousands of rubber tons. In this regard, the issue of reducing this negative phenomenon is urgent, for which it is necessary to know what and how affects tire wear. Factors affecting the wear of elastic wheels can be different: recipe of the rubber compound, the amount of traction (or braking) force in contact with the road, the type of movement is straight or cornering, the installation angles of the wheels (camber and toe-in angles), tire design, driving mode - uniform or with acceleration (braking). In this paper, we consider the influence on tire wear of such parameters as the value of the longitudinal force acting in the contact, the camber and toe-in angles, the radius of the motion trajectory and such a structural parameter as the convexity of the tread. When assessing the wear intensity, as is accepted by most researchers, we proceed from the fact that wear is proportional to the friction power in the contact of two interacting bodies.
Features of calculation and design of pavement enduring prolonged static load
Authors: Korochkin A V 
Published: June 2020

Abstract
The main calculation in the design of pavement is the calculation of the dynamic load. Calculation of static load is recommended in some cases specified in regulatory documents. It is necessary to prove that the calculation of the static load is required for any calculations of pavement. Using the calculation of pavement as an example, it is proved that a design that can withstand dynamic load does not always withstand static load. For the first time, a recommendation is given on the need to calculate the static load for any calculation of pavement, and not only in the cases indicated in the regulatory documents. It is proved that calculations for static load must be performed for any calculations of pavement. It is noted that different regulatory documents give different parameters for the calculation; therefore, before the start of the calculation, it is recommended to decide on which regulatory documents the calculation will be made.

Published: June 2020

Abstract
The current trend in the development of motor-and-tractor diesel engines imposes tough requirements on fuel equipment and the fuel supply process. The implementation of it is difficult to combine with the requirements of reducing heat generation at the initial stage of combustion and the rate of pressure increment to reduce exhaust emissions and engine noise. A decrease in the duration of the injection process and an increase in the volumetric feed rate lead to a growth in the cycle dynamism factor and an increase in the operation noise. This scientific article discusses the use of multiple injection of fuel in a diesel engine to reduce the emission of nitrogen oxides, smoke and particulate matter by improving the heat transfer processes, the mixture formation and, as a result, heat generation. Low exhaust gases toxicity and smokiness values are achieved.

Abstract
Reduced wear of rails and wheels of rolling stock is a very important task of railway transport. Solving this problem not only in-creases the lifespan of wheels and rails, but often leads to a positive reduction of fuel consumption for train traction, reduces noise when the train moves in curves. The intensity of wear of rails and wheels of rolling stock depends on many factors. The practice of Ulan Bator railway shows that since 1992, the flange of the wheels has started to wear out intensively, thereby increasing operating costs to repair and reducing service life of the railcar wheel pairs. In order to determine comprehensive measures for the rotation of wheel pairs as well as to determine the intensity of wear of the flange thickness of railcar wheel pairs, experiments have been con-ducted on the wear and turning of wheel pairs of freight cars. To substantiate comprehensive measures for the rotation of wheel pairs and determine the intensity of wear of the flange thickness of the railcar wheel pairs, experimental tests on a freight car after the overhaul with the 33-mm flange thickness have been carried out throughout the year.

Abstract
Reduced wear of rails and wheels of rolling stock is a very important task of railway transport. The flange profile studies were conducted to determine the machining sizes for the flange of railcar wheel pairs. The studies made it possible to determine that the rejection criterion characterizing dangerous form of the flange wear is a horizontal projection forming the worn-out surface of the flange between the points located at about 2 mm below its top and 13 mm above the average taping line. There are calculations made on the wear of the wheel pairs of gondola cars of the EC70 model manufactured in China after three years of operation.
