MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641048638 A) filed by Dayananda Sagar College Of Engineering, Bangalore, Karnataka, on April 16, for 'autonomous traffic signal control system using sound energy harvesting and environmental sensors.'
Inventor(s) include Mrs. H D Aparna; Mrs. Sanjana M Nagaraj; Mr. Anil D; Dr. Saba Tahseen; Dr. Archana Nandibewoor; Ms. Sanjana Shankar; and Ms. Navya Sk.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an autonomous traffic signal control system powered by sound energy harvesting from vehicular noise. The system utilizes piezoelectric sensors to capture vibrations generated by moving vehicles and convert the mechanical energy into electrical energy. The harvested energy is rectified using a bridge rectifier circuit and stored in energy storage units such as capacitors. The stored electrical energy powers traffic signal light-emitting diodes (LEDs) and associated control components without relying on conventional power sources such as batteries or grid electricity. The system further integrates environmental sensors and intelligent control mechanisms to enhance road safety and operational efficiency. Rain detection mechanisms adjust signal timing and activate street lighting during adverse weather conditions, while an emergency vehicle detection module prioritizes ambulance movement by dynamically overriding the signal cycle. By combining renewable energy harvesting with intelligent traffic management, the invention provides a sustainable and self-sufficient solution for smart city infrastructure."
