A temporary traffic signalling system, comprising: at least two display units 1, each having a wireless receiver which is connected to a display controller; and a system controller, having a wireless transmitter, being configured to transmit a control signal. The control signal is used to change the display of one of the display units, from a “stop” signal to a “go” signal. The system controller is further configured to prevent any further control signals from being transmitted until a reset signal has been transmitted to reset the display units. The display units may further comprise wireless transmitters to transmit confirmation signals, confirming the receipt of a control signal. The system may operate using distinct “phases” or “channels” and the control signal may be coded to indicate the selected phase or channel. The display units may comprise an array of lights, switchable to display either a “stop” signal or a “go” signal.
