in tunneling; and the application of these potentials for move- ment of goods as well as people.
The more promising of these new systems are:
⚫ Dial-a-Bus: A bus type of system activated on demand of the potential passengers, perhaps by telephone, after which a computer logs the calls, origins, destinations, location of vehicles and number of passengers, and then selects the vehicle and dispatches it.
⚫Personal Rapid Transit: Small vehicles, traveling over exclusive rights-of-way, automatically routed from origin to destination over a network guideway system, primarily to serve low- to medium-population density areas of a metropolis.
⚫Dual Mode Vehicle Systems: Small vehicles which can be individually driven and converted from strect travel to travel on automatic guideway networks.
⚫Automated Dual Mode Bus: A large vehicle system which would combine the high-speed capacity of a rail system operating on its private right-of-way with the flexibility and adaptability of a city bus.
⚫Pallet or Ferry Systems: An alternative to dual mode vehicle systems is the use of pallets to carry (or ferry) conventional automobiles, minibuses, or freight automatically on high-speed guideways.
⚫Fast Intraurban Transit Links: Automatically controlled vehicles capable of operating either independently or coupling into trains, serving metropolitan area travel needs between major urban nodes.
⚫New Systems for Major Activity Centers: Continuously moving belts; capsule transit systems, some on guideways, perhaps suspended above city streets.
The components and systems discussed in this report do not by any means exhaust the rich array of opportunities for innovation in urban transportation provided by the new systerns study, as the forthcoming technical reports will indicate. The recommended research and development program, projected as it is into the future, is susceptible to modification as further knowledge is gained.3
