1. A method of controlling a system of multiple traffic signals for regulating the traffic of motor vehicles, comprising:
- acquiring traffic data using vehicles;
transmitting the traffic data at least partially by wireless transmission to traffic data processing units;
analyzing a traffic situation in the traffic data processing units; and
controlling the traffic signals on the basis of a result of the analysis;
wherein the traffic data is transmitted by wireless transmission to the traffic data processing units being assigned individually to locally limited groups of traffic signals;
wherein each traffic data processing unit analyzes a local traffic situation for an environment of a respective locally limited group of traffic signals, the environment being limited by an area that extends up to, at a maximum, neighboring locally limited groups of traffic signals; and
wherein analysis of the local traffic situation is performed within a region which extends beyond the reception range of a transceiver unit of the traffic data processing unit, the traffic data required for the analysis being relayed from transmitting vehicles to the transceiver units of the traffic data processing unit via additional transceiver units.

Abstract
A method and arrangement for controlling a system of multiple traffic signals for regulating the traffic of vehicles is described. Traffic data is transmitted by wireless transmission to traffic data processing units assigned individually to a locally limited group of traffic signals, and each traffic data processing unit performs an analysis of the local traffic situation for the environment of the locally limited group of traffic signals up to, at the maximum, the neighboring locally limited groups of traffic signals.
