DIAL-A-BUS SYSTEM DESIGN - SUMMARY REPORT

A GENERAL OVERVIEW OF A DIAL-A-BUS SYSTEM IS PRESENTED WITH REFERENCE TO OPERATIONS, SERVICE, FEASIBILITY UNDER DIFFERENT URBAN CONDITIONS, POTENTIAL PEAKING PROBLEMS, PRICING AND COST ALTERNATIVES, APPLICATION OF THE COMPUTER, PREVIOUS DEMONSTRATIONS OF POINT-TO-POINT TRANSIT, DIFFERENT DIAL-A-BUS CONFIGURATIONS, INTEGRATION WITH EXISTING TRANSIT SYSTEMS, AND CRITERIA FOR DEMONSTRATION OF THE CONCEPT. IT IS CONCLUDED THAT CONCEPTUAL ANALYSIS REVEALS NO PROBLEMS FOR IMPLEMENTATION. THE REPORT EXAMINES THE MARKET POTENTIAL OF DIAL-A-BUS SERVICE, WHICH WAS DESIGNED TO FILL THE SERVICE GAP BETWEEN PRIVATE, POINT-TO-POINT MODES SUCH AS CARS AND TAXIS (WHICH ARE COSTLY TO BOTH USERS AND SOCIETY) AND PUBLIC, LINEHAUL MODES (WHOSE FIXED ROUTING MAY BE INCONVENIENT OR UNATTRACTIVE TO PASSENGERS). IT IS CONCLUDED THAT DIAL-A-BUS WOULD BE ECONOMICALLY COMPETITIVE WITHIN THESE SERVICE PARAMETERS. REGULATORY RESPONSE TO INNOVATIONS IN THE TRANSIT INDUSTRY IS EXAMINED, AND THE HISTORY OF PUBLIC TRANSPORTATION IS TRACED FROM THE EARLY 1900'S. THROUGHOUT THIS PERIOD, STATUTORY REGULATIONS HAVE HAMPERED THE APPLICATION OF INNOVATIVE TECHNOLOGY AND SERVICE. THE REPORT OUTLINES EXISTING REGULATIONS WHICH MAY AFFECT IMPLEMENTATION OF DIAL-A-BUS AND SUGGESTS POSSIBLE STRATEGIES FOR AVOIDING THEM. IN CONCLUSION, THE DEVELOPMENT, TESTING, AND DEPLOYMENT PROCEDURES FOR THE DIAL-A-BUS SYSTEM ARE DISCUSSED, AND A FIVE-PHASE PROGRAM IS ADVANCED TO COVER ALL RELEVANT ASPECTS OF HARDWARE COMPONENTS, PROTOTYPE TESTING, MARKET ANALYSIS, SYSTEM DEMONSTRATION, AND DEPLOYMENT. /UMTA/
