Abstract

Method for providing a functional road class of road segments (11) of a digital map, comprising the following steps: - regular or continuous provision (S1) of current geographical positions from a large number of vehicles (4) of a vehicle fleet (3) to a central unit (2); - Determining (S4) traversal attributes for all route segments (11) of a digital map depending on the geographical positions of the multitude of vehicles (4); - Assigning functional road classes to the respective Route segments (11) depending on the traversing attributes, where the functional road classes are defined by road class values are classified, the proportional areas of one or more travel attributes of the route segments (11) are assigned with respect to a totality of one or more travel attributes of all route segments (11) of the digital map, and - Transfer (S5) the road class values ​​assigned to the route sections (11) of the digital map to the vehicles (4) of the vehicle fleet (3).
