THE PRACTICAL IMPLEMENTATION OF COMBINATION METHOD AND TRANSIT PROGRAMS

EXPERIMENTS IN GLASGOW AND WEST LONDON HAVE SHOWN THAT SUBSTANTIAL SAVINGS IN JOURNEY TIME CAN BE OBTAINED BY CO-ORDINATING SIGNALS ON AN AREA BASIS, USING OPTIMIZED FIXED-TIME PLANS PRODUCED BY EITHER THE COMBINATION METHOD OR TRANSIT. THE PRODUCTION OF THESE PLANS INVLVES PREPARING A FAIR AMOUNT OF DATA, AND MAKING A NUMBER OF TRAFFIC ENGINEERING DECISIONS. ALTHOUGH IMPORTANT, THE WORK IS STRAIGHTFORWARD AND THE NEED FOR VERY ACCURATE DATA AND DECISIONS IS OFTEN LESS CRITICAL THAN MIGHT BE EXPECTED. THIS PAPER DESCRIBES THE STEPS INVLVED IN USING THE COMBINATION METHOD AND TRANSIT, INCLUDING SPECIFICATION OF THE NETWORK, COLLECTION AND CHECKING OF TRAFFIC DATA. CALCULATION OF CYCLE TIMES, THE USE OF COMPUTER PROGRAMS AND IMPLEMENTATION ON THE STREET. /AUTHOR/
