A vehicle navigation system (100) comprises a planning module (110) for planning a route between an origin and a destination and subsequently guides the driver along the planned route. The system further comprises a receiver (124) for the reception of traffic messages related to problem locations on roads, which messages are transferred to the driver. The navigation system according to the invention is arranged to read from its storage medium (106) with the map database additional information (404) indicating the potential problem locations for roads in the database. In this way, the information from the traffic message can be combined with the information from the map database and further exploited in the system, e.g. for planning a new route.

[ What is claimed is:] [1.]1. A navigation system for guiding a driver in a vehicle, the system comprising:read means for reading chain information from a storage medium comprising a first storage unit for storage of information on chains and nodes, a chain representing a road element and being connected to another chain via a node,processing means for exploiting said chain information comprising at least one of a planning module for planning a route or of a display module for displaying a map on a display, anda broadcast receiver for the reception of a coded traffic message corresponding to a standardized event related to a predetermined problem location whereinthe storage medium stores chains which lead to the predetermined problem locations;the read means are arranged to read from the storage medium for a particular chain related to a particular node the additional chain information linking the chain to the traffic message;wherein the planning module selects the particular chains which fall within a predetermined search area; andwherein the system is arranged to create a list of the problem locations related to the particular chains in the search area.
