This modification has simple components in its structure, which implies their easy production. As a result of modeling the distribution of the coolant in the heating device, it is shown that the installation of the above flow extension promotes uniform heating of the heater with a radiator surface temperature in the range of 58 - 64 °С, a uniform coolant temperature along the entire length of the radiator in the range of 70-65 °С compared to standard ways of connecting heating devices in the heating system.

Using the methods of probability theory, the risk of traffic accidents was determined on circular curves with radii of 600 and 800 meters, provided that the car was moving at a calculated speed. Based on the calculation results, the need to change the current standard for design is proved public roads.
