Device for forced reduction of speed with the function of generating electricity

Abstract

Problem. The danger posed by high-speed vehicles passing through crowded areas is extremely high. An analysis of the cause of accidents involving victims in Ukraine showed that speeding was the main cause for that in the city. Therefore, one of the main means of reducing the causes of road traffic accidents involving pedestrians is artificial road irregularities, also called «speed bumps». Goal. Development of a device for generating electricity and forcing reduction of the speed of vehicles at pedestrian crossings and other sections of the road where there is a need to reduce the speed of vehicles. Meth-odology. The analytical methods of research on the development and application of methods and devices for transforming the energy of the sun into electricity were used. Methods of experimental researches and mathematical methods of processing and modulation of the obtained results are used. Results. The result is the analysis of the technical solutions for the devices of forced reduction of the car speed. The design of the device of forced reduction of the car speed with the function of electricity generation is developed, as well as its schematic drawings and the schematic diagram, which are shown. The principle of opera-tion of the developed device of forced reduction of car speed is revealed. One of the variants of the pe-destrian crossing with additional lighting and laser signaling system is offered, which is equipped with devices of forced reduction of car speed with the function of electricity generation. Originality. The amount of electricity that the proposed device is able to generate is modulated (depending on the traffic intensity) from 60 kW to 400 kW. Practical value. The implementation of the proposed development into road construction will lead to the implementation of energy-efficient technologies in this field and will significantly improve road safety. Pedestrian crossings equipped with additional lighting and a laser signaling system to alert road users when using these devices will receive power from a decentralized, renewable power source.
