Abstract
A process for the wireless transmission of data to a traffic sensor for assessing traffic in segments of a road network includes collecting data in a plurality of floating cars that travel in traffic and have sensor system for collecting the data. A current driving profile is formed in each floating car from the collected data. Actual values of characteristic driving profile properties are derived from the current driving profile and expected values of the characteristic driving profile properties are formed based on preestablished traffic situation information. A difference between the actual values and the expected values is determined and if the difference is determined to be a serious deviation from the expected values based on preestablished decision criteria, the data collected by the sensors is transmitted to a traffic center.
