摘要

This paper reviews an advanced traveler information, advisory, and emergencynotification and security service being designed and tested by NYNEX Venture Company in collaboration with other private companies, state and local agencies, and a university. This service, known as Project NorthStar, has been tested in the New York City metropolitan area with the use of cellular telephony, global positioning system (GPS) technology, and a geographical informational system (GIS). Plans are underway to continue this test for the purpose of evaluating the costs and benefits associated with low-cost FM subcarrier communication technology and a portable digital assistant and speech synthesizer.
