1. A process for wireless transmission of data for traffic system assessment in segments of a road network to a traffic center, comprising the steps of:

  • collecting data using sensors in a floating vehicle in the road network;

    forming a current driving profile from the data;

    deriving actual values of characteristic driving profile properties from the current driving profile;

    forming expected values of characteristic driving profile properties based on preestablished traffic situation information;

    comparing the actual values to the expected values;

    assessing a difference found in said step of comparing and determining whether the difference is a serious deviation from the expected values based on preestablished decision criteria; and

    transmitting the actual values to the traffic center if it is determined that the difference is a serious deviation in said step of determining.
