Новий тип світлоповертального елемента на транспортне огородження першої групи

Abstract. Problem.  The paper proposes a new light-reflecting element applied to the transport fence of the first group.  Its technical characteristics are provided; as an experiment, the elements are installed on the streets of Kyiv. The speed of visual orientation and search movements of drivers was studied using the example of a new light-reflecting element. As you know, a light-reflecting element is a device designed to reflect a light beam towards the source with minimal scattering. Light reversal is the process of changing the direction of the beam by 180º through the application of double reflection. In addition to the elements discussed in subsection 3.1, the author proposed, patented, and implemented one further element that received positive feedback from road users - an additional element for the traffic fence of the first group. The use of this element on a concrete fence, which is also referred to as a delta-block or New Jersey, deriving its name from the city where it was implemented for the first time, looks especially relevant. Purpose and setting of the task. The goal is to introduce a new reflector element, which, in the author's opinion, will significantly increase traffic safety on public highways, streets, and roads in populated areas. The experiments conducted make it possible to talk about the stable dependence of the presence of additional safety elements on the driver's acceptance of management actions. Results. Difficulties in finding individual numbers usually indicate an uneven pace of the driver's mental activity. An increase in the time to search for elements on the last tables indicates the onset of fatigue and asthenia of the nervous system. The results obtained are quite different; the maximum discrepancy from the standard is 2.2 times. This may indicate that there may be a substantial variation in the drivers' physical capabilities and training levels; this should be considered in further research as one of the factors contributing to the interaction of subsystems of the V-A-D-S system.
