It is a full A-SMGCS (advanced - surface movement guidance & control system) which is being introduced at DXB. System works out where the aircraft needs to go and automatically does the route, taking into account other aircraft, does the greens, does the stopbars etc all using the ground radar to follow the aircraft. Controller can manually intervene if required. No lighting operator (there only ever is one during LVOs). Many airports are using A-SMGCS now at various levels.
