Method and system for generating map data and information delivery apparatus

An in-vehicle navigation apparatus includes the following: a master road regulation data table which stores a master road regulation data to be associated with road segments as applied targets; a temporary road regulation data table, which is prepared apart from the master road regulation table and stores temporary road regulation data to be associated with road segments and applied in preference to the master road regulation data; and a data determination unit which determines with respect to each road segment an application of either the master road regulation data or temporary road regulation data based on reference information for determining road regulation data validity. The determined road regulation data is outputted.

A mobile radio communication device for an automatic toll collection system executes toll charging processing and travel guide. It communicates with road-side communication devices at an entrance gate and an exit gate in a toll charge area to receive map data. It also receives present position information from a GPS receiver circuit. It executes processing necessary for toll charging based on the received map data and present position information. It also provides a travel guide in the toll charge area.
