Road safety in steppe areas has hardly been studied from the point of view of ensuring safety. Driving on monotonous, uniform open flat terrain is associated with increased fatigue and decreased attention for drivers, and loss of control over speed. Road conditions are significantly complicated in the hot summer time of day. Hot weather greatly changes the traffic situation, affecting the condition of the road surface and the driver's well-being, who begins to feel increased fatigue, a kind of drowsy state bordering on sleep—“road hypnosis”, a characteristic inhibited state of higher nervous activity. Very important and practically unstudied for road conditions is the effect of ambient air temperature on the neuropsychic state and the degree of emotional tension of the driver in such conditions. The hypnotizing effect of excessive “glare” - “blinding effect”, expressed in the form of a mirage on the roads and glare on the hood of a car (“Sahara effect”) has never been considered. The article examines the causes of “glare” (in the daytime) on roads. Empirical formulas for determining “glare” are given and measures to improve the condition of the road surface are given. Research has revealed a new type of negative environmental indicator of the quality of the environment on motorways. Identification of the situation requires the use of practically new design and technological solutions, as well as the development of new road-building materials with appropriate physical and optical properties within the framework of the applied science of road surface design.
