A movable traffic signal apparatus for use in controlling the movement of traffic or people on a temporary basis comprises: at least one movable traffic signal 100, 200 comprising an illuminated sign 5; a receiver for receiving control signals on one of two different radio frequency bands; a drive circuit arranged to drive the lights of the illuminated sign according to the received control signals; and a transmitter arranged to transmit control signals; and further including switching means enabling the apparatus to be configured to transmit and to receive control signals in either the first radio frequency band or the second radio frequency band. The two bands allows greater flexibility of installation when the apparatus is to be used in environments where there may be lots of interference or noise.
