Airport demand studies should also be directed towards the following problems: 1) The present relationships between daily air passenger and cargo volumes at individual airports and the volumes of vehicles required to serve those activity levels. 2) The time distribution of travel to airports (for each airport function) and the relationship of the time distribution to overall aviation patterns and air trip purposes. 3) The possibility of separating airport functions spatially to distribute vehicle demands to more than one interchange or freeway facility. 4) The sensitivity of all the foregoing relationships to new aviation technology, including' 'jumbo'' aircraft, VSTOL development, supersonic travel, and improved ticketing and baggage handling.
