TOPICS IN THE DESIGN OF DIAL-A-RIDE DEMONSTRATION EXPERIMENTS

IN DISCUSSING GENERAL CONSIDERATIONS THE AUTHORS NOTE THAT CONTROLS ARE NECESSARY IN REAL-WORLD EXPERIMENTATION WHERE FACTORS OUTSIDE THE DEMONSTRATION PARAMETERS MAY SERIOUSLY AFFECT RESULTS. INITIAL PROBLEMS IN DEMONSTRATION DESIGN ARE ALSO SUMMARIZED. TWO BASIC PROBLEMS THAT AFFECT FULL-SCALE DESIGN ARE DETERMINING THE LENGTH OF TIME NECESSARY FOR A DEMONSTRATION TO ACCOMPLISH ITS OBJECTIVES AND SELECTING INDEPENDENT VARIABLES SUFFICIENTLY NUMEROUS TO YIELD MEANINGFUL DATA, BUT SUFFICIENTLY LIMITED TO PERMIT CONTROL. THE EFFECTIVE MONITORING OF REAL-WORLD EXPERIMENTATION IS DISCUSSED WITH REFERENCE TO OPERATIONS, DEMAND, SYSTEM USE, AND OTHER FACTORS AFFECTING LONG-TERM IMPLEMENTATION. A FOUR-PHASE APPROACH TO A DEMONSTRATION PROJECT IS PROPOSED: (1) PRE-SERVICE PREPARATION (FIELD TESTING OF PROTOTYPE EQUIPMENT, ORGANIZATION OF PERSONNEL AND FACILITIES AT THE DEMONSTRATION SITE, AND EVALUATION OF INDIVIDUAL SYSTEM COMPONENTS); (2) PILOT SERVICE (OPERATION OF A LIMITED PUBLIC TRANSPORTATION SERVICE WITHIN A HIGHLY RESTRICTED AND CONTROLLED TEST AREA); (3) STAGE-ONE FULL SERVICE (EXPANSION OF PILOT SERVICE INTO A WIDER AREA WITH SUBSTANTIAL MONITORING OF OPERATIONAL PERFORMANCE AND USER OPINIONS); AND (4) STAGE-TWO FULL SERVICE (OPERATION OF THE MATURE SYSTEM AND CONDUCT OF MAJOR IN-SERVICE TESTS). TEST, EVALUATION, AND SERVICE ELEMENTS ARE DELINEATED AT LENGTH. /UMTA/
