Abstract

A method for acquiring traffic data from vehicles equipped with at least one decentralized unit having at least one function for mobile communication a second function for obtaining time information and a third function for data storage. At least one central unit with control functions and processing functions assigned to a plurality of decentralized units, wherein decentralized unit receives and evaluates information characterizing radio cells, and other technical radio and transmission information and information which characterizes cell changeover is recorded together with time stamps.
