Abstract
A process for analyzing a traffic network uses a source file including edges and nodes representing the traffic network. The process generates partial routes from the source file, wherein each partial route comprises at least one edge and at least one of the partial routes comprises a plurality of adjoining ones of said edges. Route data can be transmitted between a vehicle and a traffic center by designating the partial route instead of each individual edge, thereby optimizing transmission of data via a transmission channel.
