Abstract

A digital card of a highway network is provided in the form of a traffic file in a traffic data control center and in a terminal. Sections of streets or lanes or groups of streets or lanes are each represented as a segment in the digital card. Data pertaining to a chain of segments which follow each other in a numerical sequence in the highway network are combined in the control center into traffic data packets. Each traffic data packet contains (a) an identifier symbol representing the identity of the segment at one end of the chain, (b) a numerical chain segment symbol representing the total number of segments in numerical sequence in the chain, and (c) at least one condition symbol representing the condition of at least one of the segments in the chain The traffic data packets are transmitted to the terminal, where they are decoded and route information is output to a terminal user.
