STUDY AND DEVELOPMENT OF CRITERIA FOR THE SWITCHING OFF OF TRAFFIC SIGNALS FROM TIME TO TIME IN THE URBAN TRAFFIC NETWORK |
摘要: |
NUMBERS OF TRAFFIC SIGNAL INSTALLATIONS IN URBAN AREAS HAVE INCREASED VERY RAPIDLY SINCE, AS WELL AS BEING A USEFUL MEANS OF INCREASING SAFETY AT JUNCTIONS, THEY OPTIMIZE TRAFFIC FLOW. THE INSTALLATION OF TRAFFIC SIGNALS CAN ONLY BE JUSTIFIED BY THE CRITERIA OF TRAFFIC GUIDANCE AND FLOW I.E. DURING PERIODS OF HIGH TRAFFIC VOLUMES. DURING PERIODS WHEN THERE IS LITTLE TRAFFIC, I.E. AT NIGHT, IT MUST BE ASSUMED THAT A LARGE NUMBER OF THE SIGNALS ARE A HINDRANCE TO THE FLOW OF TRAFFIC, AND THAT SWITCHING OFF MIGHT BE RECOMMENDED IF SAFETY WERE NOT IMPAIRED. THE OBJECT OF THE RESEARCH IS TO STUDY AND DEVELOP CRITERIA AND PROCEDURES WHICH CAN AID DECISIONS ON WHETHER TO SWITCH OFF TRAFFIC SIGNALS FROM TIME TO TIME. A CATALOGUE IS TO BE PRODUCED WHICH CONTAINS CRITERIA RELATING TO SAFETY, CAPACITY AND ECONOMICS. THE PRINCIPLES ARE TO BE DERIVED FROM TRAFFIC ENGINEERING DATA AND FROM COST BENEFIT STUDIES. |
