AUTOMATIC CONTROL OF VEHICLES AND PASSENGER COUNTS

TRAFFIC CONGESTION /BOTTLENECKS AT TRAFFIC LIGHTS, OBSTRUCTIONS CAUSED BY ACCIDENTS, ETC./ REDUCES THE EFFICIENCY OF THE STREETS AND MAKES SYSTEMATIC OPERATION OF PUBLIC TRANSPORT SERVICES EXTREMELY DIFFICULT. TRANSPORT UNDERTAKINGS SHOULD THEREFORE INVESTIGATE WHETHER AN EFFECTIVE IMPROVEMENT IN SERVICES CAN BE ECONOMICALLY ACHIEVED BY THEIR OWN TRAFFIC CONTROL MEASURES. BUS SERVICE TRAFFIC CONTROL IS INVESTIGATED. EXISTING SYSTEMS ARE DESCRIBED AND COMPARED. THE LOCATION SYSTEM WORKS WITH ROUTE CHECKPOINTS, USING VERY SHORT RANGE TRANSMITTERS TO SEND OUT A HIGH FREQUENCY CODE CORRESPONDING TO THEIR LOCATION. THIS SYSTEM, HOWEVER, DOES NOT MAKE POSSIBLE THE SITUATION OF VEHICLES IN RELATION TO THE OVERALL OPERATION OF THE LINE. THE TIME SYSTEM IS BASED ON SCANNING THE BUSES ON A ROUTE AT FIXED TIME INTERVALS. THE VEHICLE APPARATUS AND CONTROL SYSTEM FOR BOTH SYSTEMS ARE DESCRIBED. THE ADVANTAGES AND DISADVANTAGES IN BOTH SYSTEMS FINALLY RESULTED IN THE ADVANTAGES OF A TIME-BASED SYSTEM AND A LOCATION-BASED SYSTEM BEING COMBINED IN THE VEHICLE CONTROL SYSTEM IN HAMBURG, GERMANY.
