The invention concerns a navigation aid method in a motor vehicle onboard system, comprising at least a locating module, a receiver of traffic data and a navigation database modelling the road network, such that it comprises a permanent training phase with: automatic identification of road sections while the vehicle is moving over part of the network at least; establishing average conditions of the road traffic on said identified road sections, by measuring the real travel time when the vehicle moves along the section, and based on travel times broadcast by a RDS-TMC of GSM operator, for example; optionally memorising a route on the basis of the identified road sections; and a phase restoring traffic data on said route in speech, graphic or textual form. |
