A novel method, system and protocol for providing continually updated traffic (and other) information from a central station to preferably telephonically linked caller customers (though other communication links are feasible), involving enabling the caller to enter on the caller\s keyboard a code for the particular zone for which a traffic information report is desired, and thereupon to receive a transmission of such report from the central station; and then, by further caller keyboard entries, requesting reports on additional specified zones－all on the same call－and further requesting from the station, by keyboard entry, automatic updating report(s) in the specified zone(s) in the event of significant changes in traffic information (including traffic incidents) during a predetermined time after the initial report.

A traffic information telephone channel communication system interconnecting a central station and a plurality of telephone callers, including mobile or vehicular telephone callers, distributed in different zones throughout a geographical area and all telephonically linked by land lines or radio links with said station, said system having, in combination, a central station provided with means for collecting and updating traffic information useful for said callers from a plurality of sources and on a real-time and continual basis for all the zones throughout said area, and means for organizing and preparing the same for computer-controlled audiotext traffic report transmission to callers through voice messaging equipment; said computer being provided with means for handling call-ins and validating pay-per-caller and subscriber caller calls, and a separate database for storing and retrieving caller phone-numbers for later call back look-up and triggering; means responsive to the validated call for thereupon responding to the entering by the caller on the caller\s telephone keyboard of a code for a particular zone of interest so specified by the caller, by transmitting-back to the caller from the station a report of the traffic information requested by the caller and in the particular caller-specified zone; means responsive to the caller\s further keyboard entry requesting both automatic updating of significant changes in the traffic information within said caller-specified zone and caller-specified and controlled variable time period following said report, by storing the caller\s telephone number in said database for such purpose; and means responsive to the determination at the central station of such significant changes in that zone within that caller-specified time period for triggering the look-up of said database and call back by the station to the caller of an updated traffic report in said specified zone.
