System for and method of controlling vehicles in a closed transport system. A closed transport system network controller generates a route for a requested journey, determining the commencement time of the journey from the origin point such that the vehicle executes the journey free of collisions with other vehicles in the closed transport system. The network controller provides steering and speed instructions in order for the vehicle to execute the route in the prescribed manner. The network controller controls all vehicles in the closed transport system such that, on a macro level, the capacity of the closed transport system is generally maximized.
