selecting a cell identifier in a control vehicle and transmitting the selected cell identifier and the identifier of the control vehicle to the switching server;
associating the control vehicle identifier with the recording vehicle identifier for which a cell identifier that is identical to the selected cell identifier is registered;
detecting a traffic or toll violation of an on-board unit or of a vehicle carrying the same and reading the vehicle license plate number thereof by the recording vehicle;
transmitting a violation data record, containing the read license plate number and the recording vehicle identifier, to the switching server, determining the assigned control vehicle identifier, and transmitting the violation data record to the control vehicle identified by the determined identifier; and
