aTNC, or autonomous Transportation Network Company, refers to a transportation service that utilizes autonomous vehicles to provide rides to passengers. Unlike traditional ride-hailing services, aTNCs operate without human drivers, relying on advanced technologies like AI and machine learning for navigation and safety. These companies aim to enhance mobility, reduce traffic congestion, and improve overall transportation efficiency through the deployment of self-driving cars. As the technology matures, aTNCs are expected to play a significant role in the future of urban transportation.
