1. A process for tamper-proof measuring of vehicle occupancy of passengers in transportation means, comprising the steps of:

  • (1) disposing a measuring device completely inside the transportation means for automatic recording of passenger utilization data, said measurement being executed several times or continuously;

    (2) automatically counting the number of passengers in the transportation means utilizing passenger detecting means individually assigned to each seat of the transportation means, said detecting means being sensitive solely to specific physical characteristics identifiable with human beings comprising breathing frequency, heartbeat, body move thereby assuring that the number of persons measured in the vehicle does not exceed the number of persons actually present, so that manipulation of occupancy data by deceitfully increasing the number of passengers is possible or at least made very difficult; and

    (3) processing, storing and displaying the data recorded in the measuring device.
