Technical electrogenerating tools for road facilities: systematics and design specifics

Abstract

BACKGROUND: Currently the Russian Federation Government has a strong focus to roads safety. This is due to the national project Safe High-Quality Roads. One of tools of pedestrian safety in an urban are road bumps. They are need for drivers speed slow.
 Contrarily world scientists create alternative sources of electrical energy. It led to tools type as technical electrogenerating devices.
 Whereas technical electrogenerating tools have big amount of developments by russian and world scientists. But in modern scientific literature there is no systematic concept about this tools type.
 AIMS: The paper purpose is knowledge summary about technical electrogenerating tools and develop their classification.
 METHODS: Energy of a moving car is accumulated and converted into electrical energy by devices type. Concept of technical electrogenerating tools is based on convertion of energy pulse of speed bump into electrical energy at the moment of car runover. This energy can be used for electricity supply of road infrastructure (crosswalk lighting, road sign ligtht, powering traffic lights).
 RESULTS: The basic classification feature of these tools is device type converting moving car energy into electrical energy: piezoelectric, hydraulic, electromechanical. In turn technical electrogenerating tools with electromechanical converter are classified by criteria: amount of motor, type of transmission mechanism, design of pressing platform and type of generator.
 CONCLUSIONS: The developed classification provides to systematize contributions of russian and world scientists designing devices of technical electrogenerating tools.
