In this work, we investigate the use of active reconfigurable intelligent surfaces (A-RIS) to enhance the performance of vehicle-to-everything (V2X) communication systems, addressing limitations seen in traditional vehicular communication systems. We tackle this challenge by formulating an optimizat...
