DISPOSITION OF EMPTY VEHICLES IN A PERSONAL RAPID TRANSPORTATION

A basic vehicle management function, associated with operation of a Personal Rapid Transit (PRT) System, is that of continually redistributing empty vehicles throughout the system. In this report a procedure for performing this function is developed and evaluated. The procedure, carried out periodically (e.g. every few minutes) consists of three steps: (a) estimation of the surplus or deficit of empty vehicles at each station; (b) allocation of surpluses to deficits; and (c) preparation of a dispatch list for each station, based on the allocations, the list giving the disposition of successive empty vehicles as they become available. Two computer simulations were constructed to evaluate the procedure. Simulation runs demonstrated that the procedure worked well.
