Abstract: A large amount of mechanical energy can be generated when vehicles are rolling on the road, and the energy can be harvested to power small electromechanical systems in the traffic environment, to realize self-powered traffic monitoring and traffic control, etc., so that the traffic system can operate more safely, orderly, and efficiently. Vehicle-road energy harvesting is green and environmentally friendly, and is beneficial to the realization of China's "dual carbon" goal. This paper proposes an anti-impact vehicle-road energy harvesting bump(AVEHB) for one-way lanes. By "homeopathic movement" to absorb vehicle rolling energy, the impact to the energy harvester and roadbed can be reduced, and more rolling force can be used for energy harvesting. The comparison experiments verify the advantages of the design. Based on the working principle of AVEHB, the electromechanical coupling dynamic一model is established and verified by experiments. The experimental results show that when the vehicle speed is 50 km/h, the maximum output voltage and power of AVEHB are 146.7 V and 143.47 W, respectively. The self-powered vehicle speed monitoring system and pedestrian active safety applications have been explored, which proves that AVEHB has the potential to power small electromechanical systems in traffic environments. By reasonably setting up the AVEHB network, it is possible to provide convenient, sustainable, environmentally friendly zero-carbon electricity for the smart transportation system.
