Method and system for transmitting dynamic road traffic data to a user terminal

摘要

The invention relates to a method for delivering road traffic data to at least a first position enabled user terminal of a plurality of position enabled user terminals, each of said position enabled user terminal being embarked on board a vehicle moving within a road infrastructure, said user terminal being connected through a telecommunication network to a road traffic management server. According to the invention, the present method comprises the acts of:
–  receiving (400) at the road traffic management server positions and speed data from the plurality of position enabled user terminals,
–  estimating (401) road traffic data at a plurality of predefined checkpoints belonging to a mesh of redefined checkpoints matching the road infrastructure using the received positions and speed data;
–  producing (404) a road traffic estimated map by associating each redefined checkpoint with its estimated road traffic data;
–  transmitting (405) a portion of the road traffic estimated map to the first position enabled user terminal for subsequent display of said portion.
