DIAL-A-RIDE DEMONSTRATION IN HADDONFIELD: PLANNING AND INITIAL OPERATION

A SURVEY WAS CONDUCTED AND THE RESULTS WERE USED IN REACHING DECISIONS CONCERNING INITIAL OPERATING PARAMETERS FOR THE HADDONFIELD DEMONSTRATION. THE SURVEY MEASURED TRIP CHARACTERISTICS IN THE INITIAL SERVICE AREA AND DETERMINED MODAL SPLIT AND CHARACTERISTICS SUCH AS TRAVEL TIME AND COST. DATA USEFUL IN ESTABLISHING DAR OPERATING PARAMETERS WERE OBTAINED. INFORMATION CONCERNING MODAL ATTRIBUTES AND THEIR RATINGS WAS USED TO DEVELOP A MODEL TO FORECAST DEMAND FOR THE SYSTEM. DAR USER REACTION WAS ASSESSED AND THROUGH IT RESIDENTS HAD A VOICE IN THE SELECTION OF SYSTEM OPERATIONAL PARAMETERS. GRAPHS ILLUSTRATING RIDERSHIP ARE PRESENTED AS ARE ALSO FIGURES SHOWING THE AVERAGE HOURLY WEEKDAY VEHICLE DISTRIBUTION AND AVERAGE HOURLY VEHICLE PRODUCTIVITY (DEFINED AS THE NUMBER OF REQUESTS RECEIVED PER VEHICLE PER HOUR). THREE TYPES OF SERVICE ARE OFFERED: IMMEDIATE, DEFERED, AND PERIODIC. QUALITY OF SERVICE IS ASSESSED ON AVERAGE WAIT TIME (TIME ELAPSING FROM END OF PHONED REQUEST AND TIME OF VEHICLE ARRIVAL); PICKUP TIME DEVIATION (DIFFERENCE BETWEEN THE PROMISED PICKUP TIME AND THE ACTUAL PICKUP TIME); AND RIDE TIME (TIME THE PASSENGER RIDES FROM PICKUP TO DELIVERY). GRAPHS ILLUSTRATE THESE CONCEPTS AND THE RELATIONSHIP BETWEEN AVERAGE WAIT AND RIDE TIMES AND VEHICLE PRODUCTIVITY. MEAN WAIT TIME INCREASES GRADUALLY FROM THE EARLY MORNING TILL IT REACHES MAXIMUM DURING THE 3 P.M. TO 7 P. M. PEAK PERIOD. MEAN PICKUP DEVIATION TIME IS 2.13 MINUTES AND THE AVERAGE WEEKDAY RIDE TIME IS CLOSE TO THE AVERAGE AUTOMOBILE RIDE TIME.
