Connected Autonomous Vehicles (CAVs) are cars that can drive themselves without human intervention while being connected to the internet and other vehicles. This technology uses sensors, cameras, and artificial intelligence to navigate roads, avoid obstacles, and make real-time decisions. The connectivity aspect allows CAVs to communicate with each other and with infrastructure, such as traffic lights and road signs. This communication helps improve safety, reduce traffic congestion, and enhance overall driving efficiency. As a result, CAVs have the potential to transform transportation systems and improve mobility for everyone.
