A COMPARATIVE STUDY OF URBAN TRANSIT TECHNOLOGIES: THE SERVICE SPECIFICATION ENVELOPE APPROACH

THE SERVICE SPECIFICATION ENVELOPE IS DISCUSSED AS AN EVALUATIVE TOOL FOR THE COMPARATIVE ANALYSIS AND SELECTION OF ALTERNATIVE URBAN TRANSIT TECHNOLOGIES. THE CONCEPT DEFINES THE AREA OF APPLICABILITY OF A GIVEN TECHNOLOGY AND ASSESSES THE RELATIVE QUALITY OF THE SERVICE OFFERED. ECONOMIC VIABILITY AND PHYSICAL CAPACITY ARE THE EVALUATIVE CRITERIA FOR DETERMINING APPLICABILITY WHICH IS, IN TURN, DETERMINED BY THE RANGE OF PASSENGER FLOWS FOR A GIVEN TRANSIT SYSTEM IN OPERATION. EACH VARIABLE IN THE SERVICE SPECIFICATION ENVELOPE METHOD IS DISCUSSED IN DETAIL, INCLUDING TRANSIT OPERATING COSTS, FARE STRUCTURES, AND CAPACITY LIMITS. THE QUALITY OF SERVICE IS MEASURED IN TERMS OF SPEED, MEASURED AS FEET PER SECOND. THE REPORT CONTAINS SERVICE SPECIFICATION ENVELOPES FORMULATED FOR EIGHT TECHNOLOGIES IN THE LINEHAUL OR COLLECTOR/ DISTRIBUTOR MODES. THE RELATIVE MERITS OF DIFFERENT TRANSIT TECHNOLOGIES ARE NOTED FOR VARIOUS DEMAND VOLUMES AND OTHER PARAMETERS. COST MODELS FOR URBAN BUS TRANSPORT SYSTEMS ARE APPENDED.
