Abstract

A method and system for providing and transmitting individualized traffic information from a traffic network to a user via a telephone network and at least one voice channel. Traffic information is requested by the user from an information center that is capable of searching a traffic database and includes a voice generator for transmitting searched traffic information to the user in spoken form using the voice channel. The user request to the information center is character coded and a reference code is assigned to the traffic information being searched responsive to the user's request (call) and then transmitted to the user.
