The traffic section map is preferably stored in a user device. Each section of traffic section map(or TSM) includes at least one vector entity which includes a shape designating statement (e.g. `LINE`) and a position designating statement. The traffic section map(or TSM) also includes a plurality of section discriminating code which is preferably an attribute designating command. The traffic state data for respective section is used to update or designate the attribute value (e.g. color) of corresponding to section's vector entity. The updated TSM is used for displaying traffic information-containing image along with at least one corresponding basic map which is also stored in the user device.
