Abstract
An interactive transportation information system provides schedule information to a caller utilizing a Touch-Tone type telephone. The system includes a database storing a digital code specific to each station, schedule information and a plurality of speech files for generating messages to the caller. Voice messages prompt the caller to press keypad buttons for a departure station, an arrival station, and a desired departure or arrival time. The database is then searched for a transportation vehicle departing the departure station at the time closest to the desired time, whereupon a voice message is generated identifying its departure and arrival times. The system also resolves station name ambiguities and simplifies dialogue for travel to and from the stations.
