In China, engineers have introduced Autonomous Rail Rapid Transit (ART) systems that operate on city streets by following virtual tracks marked with painted dotted lines. These vehicles rely on LiDAR, high speed sensors, and AI based vision systems to read the road surface and maintain precise alignment, without the need for physical steel rails. The economic benefits are substantial. Building an ART system costs roughly one fifth of a conventional tram network. By removing the need for rail ins
