  • Traffic control system using phase shift fiber Bragg gratings

    The article uses a method of modernizing solutions for constructing vehicle monitoring models made using standard Bragg structures. The applicability of fiber Bragg gratings (FBGs) with structural defects such as phase shifts is carried out. This article proposes a fiber-optic sensor system (FOSS) based on FBG with a phase π-shift, which makes it possible to switch from optoelectronic interrogation methods to radio-photonic ones. The radio-photon approach is presented as an effective method for detecting vehicles in normal traffic. The principle of information signal formation when measuring vehicle parameters. This FOSS allows, on the one hand, to get rid of an expensive optoelectronic interrogator, on the other hand, it requires the construction of neural network models for its work to determine cars of different types and weights.

  • Influence of temperature and heat exchange processes of the external environment on the operation of the engine neutralize

    In modern conditions, internal combustion engines (ice) are the most popular power plant for a number of transport vehicles: cars, tractors, locomotives, river and sea transport vessels. Strict requirements of modern Euro-standards to the degree of "smokiness" of exhaust gases of diesel internal combustion engines and their toxicity contribute to the emergence of a dead end situation. It is almost impossible, using obvious technical solutions, to comply with the requirements of Euro-5 and Euro-6 standards while maintaining the acceptable growth in economic costs, internal combustion engines (ice) emit a significant amount of exhaust gases into the atmosphere, which is an environmental threat. The article considers the method of SHS technology and its advantages.

  • Determination of intensity of movement of motor roads of local importance, located on the Factory highway in Samara

    The problem of major repairs on the factory highway in Samara still remains unresolved, although the issue has been acute for many years. During this time, as statistics show, there were a lot of accidents and damage to vehicles. A heavy load on the roadbed leads to rapid wear of the asphalt surface, as a result, almost every year the Factory highway needs repairs. The load on the highway will increase even more when the section of road connecting the new Kirovsky bridge with the Zavodsky highway is built. The automobile road in Samara along the ZAVODSKOE highway needs major repairs for several years, but the work does not begin, and every spring its condition worsens more and more. The issue remains relevant today.
