Microcontroller based self sustaining automatic traffic light control using speed breaker

Present development of the world is measured by the amount of energy consumption. Energy of today world is generated from conventional energy sources mostly which are decreasing day by day. Moreover, these conventional energy sources causes pollution and responsible for global warming of the world. To solve these problems, researchers are trying frequently to explore new sources of energy which are clean, environment friendly, sustainable. This project is focused on auto traffic light control using energy conversion by speed breaker. Generated voltage depends on spring constant, displacement of rack length, gear ratio, number of gear combination, number of vehicle. Here the procedure is discussed to increase the efficiency. The automatic traffic light control circuit control the vehicle flow automatically. Charging circuit charges the battery. The advantages of this project are discussed here.
