ROUTE GUIDANCE SYSTEMS FOR IMPROVING URBAN TRAVEL AND LOCATION CHOICES. IN: TRANSPORT AND INFORMATION SYSTEMS

Technological advances in navigation systems for private vehicles have the capability to provide drivers with highway route information on a dashboard-mounted video display screen. These technological advances, together with 2-way radio communication of digital information, automatic measurement of traffic flows, and supercomputer technology, could be combined to provide useful data to drivers concerning expected travel time, route selection, and best departure times. This paper reviews the status of this technology and explores the information and prediction requirements for the computer models needed to implement such a system. Research required to evaluate the potential impact of such a system is also described.
