GEOMETRICS AS AN APPROACH TO MACROSCOPIC THEORIES OF TRAFFIC FLOW

GEOMETRICAL TREATMENTS OF TRANSPORTATION RELATIONSHIPS ARE PRESENTED TO PROVIDE A CONVENIENT METHOD FOR COMPACT STORAGE OF LARGE AMOUNTS OF INFORMATION AND A BASIS FROM WHICH NEW THEORIES MAY BE IDENTIFIED. THE GEOMETRICAL SCHEMA ARE A PART OF A MACROSCOPIC APPROACH TO TRAFFIC FLOW SINCE THE EFFECTIVENESS OF ANY GIVEN TRANSPORTATION LINK IS TO BE DEDUCED FROM MEASUREMENTS MADE AT INBOUND AND OUTBOUND CORDON LINES WITHOUT MAKING ANY INTERVENING MEASUREMENTS. THE PURPOSES OF MACROSCOPIC FORMULATION ARE TO PROVIDE BASES FOR MAKING TRAFFIC FLOW THEORY MORE READILY APPLICABLE TO OPERATIONAL PROBLEMS AND TO LINK TRAFFIC FLOW THEORY TO THE LARGER PICTURE OF URBAN AND REGIONAL PLANNING. THE GEOMETRICAL SCHEMA ADVANCED ARE DELIBERATELY CONSTRUCTED TO REDUCE THE VARIANCE OF ESTIMATES OF TRAFFIC PARAMETERS, NAMELY, SYSTEM CHARACTERISTICS AND THE LOADING ON THE SYSTEM.
