Background: A siren is a special signal given by emergency vehicles such as fire trucks, police cars and ambulances to warn drivers or pedestrians on the road. However, drivers sometimes may not hear the siren due to the sound insulation of a modern car, the noise of city traffic, or their own inattention. This problem can lead to a delay in the provision of emergency services or even to traffic accidents. Aim: develop an acoustic method for detecting the presence of emergency vehicles on the road through the use of convolutional neural networks. Materials and Methods: The algorithm of work is based on the conversion of sound from the external environment into its spectrogram, for analysis by a convolutional neural network. An open dataset (Emergency Vehicle Siren Sounds) from sources available on Internet sites such as Google and Youtube, saved in the .wav audio format, was used as a dataset for siren sounds and city traffic. The code was developed on the Google.Colab platform using cloud storage. Results: The conducted experiments showed that the proposed method and model of the neural network make it possible to achieve an average efficiency of determining the type of sound with an accuracy of 93.3 % and a speed recognition of 0.00045 % of a second. Conclusion: The use of the developed technology for recognizing siren sounds in city noize will improve traffic safety and increase the chances of preventing a dangerous situation. Also, this system can be an additional assistant for hearing-impaired people while driving and everyday life for timely notification of the presence of emergency services nearby.

Aim: development of a high-speed transport highway in the Arctic zone, built on the widespread use of electric transport. Materials and Methods: the trestle structures are designed for combinations of operating loads, forces and impacts, including consideration of dynamic aspects and nonlinearity, using the SCAD Office software package. Results: according to preliminary technical and economic indicators, the duration of cargo delivery along the Arctic Expressway to the Bering Strait is reduced by 5.5 times compared to the Northern Sea Route (NSR), and passengers by almost 30 times, but at the same time the length of the projected expressway is almost 1.6 times higher due to the need to bypass high coastal mountain ranges. Conclusion: when designing a global land transport network, these studies confirm the possibility of using Evacuated Tube Transportation and Maglev technologies for the Arctic High-speed Transport Highway. In further studies, underwater pipelines will be considered, which will have long straight sections with a length of more than 1000 km, bypassing coastal mountain ranges and minimizing the number of transport hubs.

Materials and Methods: to obtain the results, the traction characteristics of the locomotives under consideration, data from the analysis of the traction arms of operation and transport infrastructure using the Yandex Maps navigation system, as well as Russian E2 software for creating graphic-physical 3D models with subsequent simulation, implemented in the Substance Painter and 3Ds software systems, are used max. Results: an analysis of the areas of operation of the studied locomotives is presented, indicating the advantages and disadvantages of using 3ES6 electric locomotives in the transportation process, a simulation model of the interaction of infrastructure facilities and the locomotive fleet is developed, the prospect of further research is determined in terms of carrying out calculations of a feasibility study for replacing the fleet of obsolete series locomotives. Conclusion: the obtained results of the study can be used in the organization of operational work and maintenance of 3ES6 locomotives with booster sections to improve the technology of operating a corporate locomotive fleet with a polygon structure for managing the transportation process.

Aim: Development of a new approach to optimizing the process of cargo flows distribution at the transport loop. Construction of a mathematical model of the freight transportation process, which equally takes into account the interests of various participants in the transportation process. Materials and Methods: A mathematical model of the freight transportation process is built, which is based on the infrastructure indicators of the considered part of the railway loop and is a multicriteria optimization problem of integer programming. The algorithm for solving the problem is common for land transport and is implemented in the environment of a computer algebra system. As a project, which is an example of the application of the developed transport and logistics method, a part of the North-Caucasian railway, adjacent to the main cargo ports of the Azov-Black Sea basin, is considered. The considered railway loop is a transit component, actively exploited for Russian exports, in particular, grain cargoes. Results: The issues of organizing rail freight transportation in multimodal transport and technological systems are researched on the basis of egalitarian and utilitarian approaches in welfare theory. These approaches are considered in relation to the participants in the transportation process (agents) within the framework of the time and cost indicators of this process. Computational procedures for finding optimal distributions of cargo flows have been brought to concrete results. Conclusion: A mathematical experiment used as a simulation modeling tool allows versatile and purposeful manipulation of the indicators of the transportation process and the restrictions imposed on transportation plans. The cargo flows distributions to port unloading stations obtained as a result of Pareto optimization are analyzed from the point of view of their rationality and usefulness in relation to agents.

Background: The article describes the process of occurrence of additional losses in the extreme turns of the copper stator windings, based on physical laws. The causes of the skin effect in the stator windings of a switched reluctance motor (SRM) are presented, an assessment of the skin effect influence degree on additional losses in the SRM of medium and high power. 2D-model of the SRM sector in COMSOL Multiphysics software package is created to specify distribution of magnetic field in the SRM stator windings and to quantify the amount of additional losses. А comparison of the magnetic field distribution of the SRM configuration 12/8 obtained in the FEMM program and the SRM magnetic field distribution built in COMSOL Multiphysics software package is presented to assess the reliability of the results. Aim: Calculation of the magnetic field distribution in the turns of the stator winding by building a phased 2D-model of the SRM sector (pole division) in COMSOL Multiphysics software package to quantify the amount of additional losses caused by eddy currents in the windings. Methods: COMSOL Multiphysics software package is used to build 2D-sector of the SRM. To obtain results on the distribution of electromagnetic fields within the simulated area, finite element methods (FEM) are used to estimate income adjustments, the results are compared with calculations in the FEMM program. Results: The patterns of the magnetic field distribution of the SRM obtained in COMSOL Multiphysics software package and in FEMM program confirm the presence of a skin-effect in the extreme turns of the stator winding. It can reduce the energy efficiency of the SRM and cause local overheating of the winding turns. As a result of the simulation, the picture of the magnetic field distribution of the SRM obtained in the FEMM program is similar to the picture of the magnetic field distribution of the SRM obtained in COMSOL Multiphysics software package. Ratio error of the values of the magnetic induction of different parts of the SRM is 37 %. It is acceptable and it indicates the correctness of computer modeling in COMSOL Multiphysics software package. Conclusion: The patterns of the magnetic field distribution SRM in COMSOL Multiphysics software package and in the FEMM program confirm the presence of the skin-effect in the extreme turns of the stator winding, which will allow further research in the field of determining the numerical values of additional losses using 2D-model, and proceed from 2D-model to 3D-model of the SRM.

The process of mixing mineral components with organic binders in the technology of preparation of hot asphalt concrete mixtures is considered. As a working hypothesis, the assumption of a functional relationship between the power consumption of the electric motor of the agitator and the mixing resistance is accepted. It is necessary to establish the dependence of the power consumption of the agitator drive on various technological parameters. Experiments were carried out: in laboratory and production conditions, which showed fairly simple dependencies.
