Suggestions for basic transportation research and a preview of possible developments. Basic tools needed for an analytic approach are (1) adequate national data collection, storage, and evaluation; (2) a methodology for long range, multimode traffic forecasts; (3) proper use of governmental regulation; (4) modal-split considerations — understanding the factors at work when there is a choice between two modes; and (5) traffic flow limitations. These tools can be used to solve some of the major transportation problems: adequacy of service, determination of a preferred market for a component transport mode, cargo transport, traffic flow control systems and modal interfaces, noise pollution, and the socioeconomic aspects of multimodal systems. In the future, automated aircushion vehicles traveling freeways or existing rail right-of-ways at 100 mph may link outlying regions of the megalopolis, airports, and other major transfer points. Interurban travel may be by V/STOL craft carrying 100 passengers over independent airway systems, and conventional aircraft may land at offshore ports.
