THE VARO MONOCAB SYSTEM, A BASELINE DEFINITION

THIS SYSTEM EMPLOYS A LARGE NUMBER OF SMALL, CLOSELY-SPACED, ELECTRICALLY-POWERED VEHICLES, SUSPENDED FROM A MONORAIL (GUIDEWAY) NETWORK COMPRISING A SERIES OF CLOSED LOOPS (ZONES) INTERCONNECTED BY HIGH-SPEED SECTIONS. THE VEHICLES OPERATE AUTOMATICALLY TO TRANSPORT PASSENGERS AND/OR MATERIAL ALONG THE SHORTEST ROUTE BETWEEN ORIGIN AND DESTINATION, BYPASSING ALL ZONES AND STATIONS WHICH ARE NOT INCLUDED IN THIS ROUTE. THE MONOCAB OPERATES ON DEMAND: WHEN A USER PUSHES A "CALL" BUTTON, THE CLOSEST EMPTY VEHICLE RESPONDS. WHEN NOT IN USE, THE VEHICLES PARK AT A VACANT GATE WITHIN A STATION. THEREFORE, EXCEPT DURING PEAK TRAFFIC PERIODS, A VEHICLE IS LIKELY TO BE PARKED AT THE STATIONS WHEN THE USER ARRIVES. IF A VEHICLE IS NOT AVAILABLE, THE CALL IS TRANSMITTED TO PRECEDING STATIONS UNTIL AN EMPTY VEHICLE IS FOUND WHICH CAN ANSWER THE CALL. THE MONOCAB GUIDEWAY CAN ASSUME ALMOST ANY CONFIGURATION DESIRED BY THE CUSTOMER. IT CAN BE ROUTED BETWEEN MAXIMUM ACTIVITY CENTERS, WITH ONE OR MORE LOOPS IN EACH CENTER; OR THE ROUTE CAN BE A SIMPLE DUAL GUIDEWAY WITH SMALL TURN-AROUND SECTIONS AT EACH END. THE GUIDEWAY CAN CONTAIN CURVES WITH A RADIUS OF 10 FEET AND SLOPES OF UP TO 10%. PASSENGERS ARE PROVIDED THE COMFORT, VELOCITY, AND RIDE CHARACTERISTICS OF AN AUTOMOBILE. IN ADDITION TO COMFORTABLE SEATS, LIGHTING, AND AIR CONDITIONING, THE MONOCAB VEHICLE IS EQUIPPED WITH AIR-CUSHION SPRINGS AND TORQUE--BARS TO LIMIT ACCELERATIONS AND SWAY EVEN IN THE PRESENCE OF HIGH WIND GUSTS. THE SYSTEM OPERATES AUTOMATICALLY AT SLOW SPEEDS---AROUND 10-FOOT-RADIUS CURVES IF NECESSARY---, AT VELOCITIES UP TO 34 MPH AROUND LARGER CURVES (385 FOOT RADIUS), AND UP TO 68 MPH ON LONGER-RADIUS CURVES AND STRAIGHT SECTIONS OF THE GUIDEWAY. A CENTRAL COMPUTER INSTALLATION IS NOT REQUIRED TO CONTROL EITHER THE VEHICLES OR THE STATIONS. RATHER, EVERY VEHICLE CONTAINS ITS OWN ELECTRONIC LOGIC WHICH SELECTS ITS PATHS BETWEEN ORIGIN AND DESTINATION AND CONTROLS VEHICLE ACCELERATION, DECELERATION, VELOCITY, AND TURNS IN ACCORDANCE WITH CODED INSTRUCTIONS (SIGNALS) PERMANENTLY INSTALLED IN THE GUIDEWAY. WHEN A VEHICLE DOES NOT RECEIVE CORRECT INSTRUCTIONS FROM THE GUIDEWAY, OR IF IT DOES RECEIVE THE PROPER SIGNALS FROM ANY LEADING VEHICLE, IT AUTOMATICALLY STOPS. THE VEHICLES USE PHOTOOPTIC DEVICES FOR "READING" INSTRUCTIONS FROM THE GUIDEWAY AND FOR DETECTING THE PRESENCE AND VELOCITY OF OTHER VEHICLES. /UMTA/
