Abstract
A method and apparatus for managing different traffic speeds of carriages moving along a closed-loop track is disclosed. The closed-loop track has at least four different speed zones, which include a slow speed zone, a fast speed zone, an acceleration zone, and a deceleration zone. A computerized control system monitors and controls the movement of the carriages along the different speed zones of the closed loops track, so different traffic speeds are maintained along the closed loop track, simultaneously, with no collisions.
