AUTOMATIC FARE COLLECTION: TECHNICAL REPORT NO 2 - FINAL REPORT

THREE PROTOTYPE SYSTEMS WERE TESTED AND DEMONSTRATED DURING THE PROGRAM. THE FIRST SYSTEM USED SPECIAL - PURPOSE TIME-SHARED COMPUTERS THAT FURNISHED THE ARITHMETIC CAPABILITY FOR CALCULATING THE FARE AND THE NECESSARY LOGIC AND CONTROL CIRCUITRY FOR CONTROLLING THE GATES AND VENDING MACHINES. IF THIS KIND OF FARE COLLECTION PLAN WERE PROVIDED, THE NUMBER OF COMPUTERS PER BART STATION WOULD VARY FROM TWO TO EIGHTEEN, DEPENDING ON THE TOTAL NUMBER OF GATES AND VENDING MACHINES IN THE STATION. THE SECOND SYSTEM, KNOWN AS THE COMMUTA-CODE SYSTEM WAS DESIGNED SO THAT ALL GATES, VENDORS, AND FARE MACHINES WERE SELF-CONTAINED INDEPENDENT UNITS. EACH MACHINE HAD ITS OWN ARITHMETIC CAPABILITY, LOGIC AND CONTROL CIRCUITRY. CONSEQUENTLY, NO INTRASTATION COMMUNICATION BETWEEN SYSTEM COMPONENTS WAS NEEDED. IN THE LAST SYSTEM THE FARE COLLECTION AND PASSENGER GATE CONTROL FUNCTIONS FOR ALL STATIONS WERE PROCESSED ON A REAL-TIME BASIS BY A CENTRALLY LOCATED GENERAL-PURPOSE COMPUTER. THE COMPUTER CONTINUOUSLY MONITORED GATES AND VENDING MACHINES VIA TELEPHONE LINES, AND CONSEQUENTLY WAS ALWAYS AVAILABLE FOR PROCESSING TICKET INFORMATION AND DICTATING PASSENGER GATE CONTROL FUNCTIONS AS THE NEED AROSE.
