VSTOL AIRCRAFT: THE FUTURE ROLE IN URBAN TRANSPORTATION AS A PICK UP AND DISTRIBUTION SYSTEM

THE EXISTING SHORT-HAUL TRANSPORTATION MARKET IS EXAMINED USING AS AN EXAMPLE BOSTON AND SURROUNDINGS TO A RADIUS OF FIFTY MILES. A MODAL SPLIT MODEL IS CALIBRATED TO DETERMINE TRAVEL PREFERENCES BETWEEN THE AUTOMOBILE AND COMMON CARRIER MODES AS A FUNCTION OF COST AND TIME. IT IS CONCLUDED THAT AN ECONOMICALLY VIABLE HIGH-FREQUENCY AIR TRANSPORTATION SYSTEM USING ADVANCED VTOL AIRCRAFT COULD BE DEVELOPED TO SERVE THIS AREA, EVENTUALLY GENERATING ABOUT FORTY MILLION PERSON TRIPS PER YEAR, FOR A CAPITAL INVESTMENT OF LESS THAN ONE MILLION DOLLARS PER MILE. THERE WILL BE INSUFFICIENT TRAVEL DEMAND TO SUPPORT A HIGH-FREQUENCY AIR SERVICE BETWEEN OTLYING SUBURBAN PORTS; HOWEVER, SMALLER VEHICLES COULD SERVE THIS PERIPHERAL MARKET IF THE NETWORK FLOWS COULD BE OPTIMIZED IN REAL TIME. THE DEMAND FOR THE AIR SYSTEM IS COMPARED WITH THE POTENTIAL DEMAND FOR ADVANCED HIGH-SPEED GROUND TRANSPORTATION SYSTEMS OPERATING WITH AND WITHOUT SUBSIDY, AND WITH THE AUTOMOBILE OPERATING AT BOTH APPARENT AND TRUE COSTS. IT IS CONCLUDED THAT A MIX OF COMMON CARRIER GROUND TRANSPORTATION OVER SHORTER DISTANCES AND HIGH-SPEED AIR TRANSPORTATION FOR DISTANCES BETWEEN FIFTEEN AND FIFTY MILES WOULD REDUCE AUTOMOBILE TRAVEL SUBSTANTIALLY ONLY IF CHOICE OF MODE WERE BASED ON TRUE RATHER THAN APPARENT COSTS. THE FACTORS OF NOISE, AIR POLLUTION, SAFETY, AND DISPATCH RELIABILITY FOR THE AIR SYSTEM ARE EXAMINED, AND IT IS CONCLUDED THAT THE PROPOSED VEHICLES CAN BE DESIGNED FOR NOISE LEVELS BELOW AMBIENT URBAN LEVELS, AND WILL BE OPERABLE UNDER ALL WEATHER CONDITIONS IN WHICH TRAVEL MAY BE EXPECTED. THE POLLUTION LEVELS WILL BE ORDERS OF MAGNITUDE LESS THAN THAT PRESENTLY CAUSED BY AUTOMOBILES.
