1. A method for enabling a vehicle to influence a traffic light signal system provided with an evaluation computer, said method comprising:

  • sending, via the vehicle, a data telegram to an evaluation computer to request a green phase at a sending position, at least one of the data telegram or the sending position depending on predefined reporting points,wherein the predefined reporting points are location points,wherein the data telegram is transmitted to the evaluation computer over a packet-oriented radio network and wherein in an approach of the vehicle to a reporting point the sending position is advanced as a function of a current speed of the vehicle and a maximum assumed data telegram transit time,wherein the evaluation computer calculates the transit time of the data telegram based on a difference between a reception time and a sending time on reception of the data telegram, and when the calculated transit time is smaller than the maximum assumed data telegram transit time, further processing or forwarding of the data telegram is delayed by a time difference according to the difference between the maximum assumed data telegram transit time and the calculated transit time.
