SKY-KAR TRANSIVATOR SYSTEM: A BASELINE DEFINITION

THE SYSTEM, A SHORT-HAUL, HORIZONTAL PEOPLE MOVER, IS COMPOSED OF THREE BASIC COMPONENTS. THE VEHICLES, REFERRED TO AS KARS, ARE DESIGNED TO MAINTAIN THE PERSONALIZED ENVIRONMENT OF AUTOMOBILES; THE KARS ARE SELF-POWERED AND OPERATE AUTOMATICALLY. THE GUIDEWAY, A WIDE-FLANGE I-BEAM, IS SUSPENDED BELOW SUPPORTING STANCHIONS, CEILINGS, AND OTHER MEMBERS DESIGNED TO HOLD THE GUIDEWAY BEAM AT AN ELEVATION SUFFICIENT TO ALLOW THE KARS TO TRAVEL BENEATH THE SUPERSTRUCTURES. THE CONTROLS, THAT SEGMENT OF THE SYSTEM WHICH PERFORMS THE AUTOMATION FUNCTIONS, INCORPORATE THE MOST MODERN TECHNICAL INFORMATION. COMPUTERS AND ELECTRONIC DEVICES ARE EMPLOYED TO THE EXTENT REQUIRED BY ANY GIVEN SYSTEM; THE LARGER, MORE COMPLEX SYSTEMS REQUIRE MORE SOPHISTICATION IN CONTROL OPERATION, WHILE THE SMALLER SYSTEMS CAN BE MODIFIED AND TAILORED TO MEET LESS COMPLEX REQUIREMENTS. THE VEHICLE WILL HAVE A CAPACITY FOR TWELVE PASSENGERS (SIX SEATED AND SIX STANDING); NO PROVISION ARE MADE FOR BAGGAGE. STUDIES OF AUTOMATIC ELEVATORS WITH SIMILAR CAPACITIES SHOW AN AVERAGE OF 8 SECONDS UNLOADING TIME AND 10 SECONDS LOADING TIME; PRELIMINARY PLANS FOR SKY- KAR ARE BASED ON TIMES OF 15 SECONDS FOR BOTH LOADING AND UNLOADING. THE MOTOR CONTROL SYSTEM WILL BE PROGRAMMED FOR AUTOMATIC ACCELERATION, DECELERATION, LINE SPEED, MERGE SPEED, AND A VERY SLOW SPEED (REFERRED TO AS "CREEP"); THE CREEPING MOVEMENT OF THE KAR IS USED TO POSITION THE VEHICLE ACCURATELY AT THE LOADING GATE, PERMITTING THE KAR TO STOP WITH NO PRONOUNCED BRAKING OR SUDDEN ARREST OF ITS FORWARD MOVEMENT. PROGRAMMED ACCELERATION IS ACCOMPLISHED BY A SET RAMP FUNCTION GENERATOR AND VELOCITY FEEDBACK FROM THE MOTOR; WITH CLOSE CONTROL OVER THE FEEDBACK SYSTEM, JERK IS EXPECTED TO BE MINIMAL AND UNNOTICEABLE. KARS, TO OPERATE IN A LOOP, WILL FUNCTION MUCH LIKE AUTOMATIC ELEVATORS; A CALL FROM A STATION WILL DIVERT THE NEXT PARTIALLY LOADED KAR TO THAT STATION. PASSENGERS WILL HAVE CODED TICKETS TO DESIGNATE DESTINATIONS OR, IF TICKETS ARE NOT USED, BUTTONS INSTALLED IN THE VEHICLES WILL BE USED TO IDENTIFY DESTINATIONS. INFORMATION AS TO KAR NUMBERS AND LOCATIONS IS FED TO THE CONTROL CENTRAL STATION; HOWEVER, KARS ARE UNDER THE CONTROL OF THE INDIVIDUAL STATIONS DURING THE TIME THEY ARE IN THAT AREA.
