A traffic signalling apparatus 100 comprising a signal head 106 including at least one variable-intensity light 110 (e.g. a red, amber or green light); a sensing system 112 configured to detect a range and speed of an approaching vehicle; and a controller 118 configured to vary an intensity level of the light in response to a predetermined characteristic detected by the sensing system. The speed sensor may be a radar device such as FMCW radar. The apparatus may include an ambient light sensor 116 and the controller may further modify the intensity level in response to a detected increased or decreased ambient light level. The intensity level may vary between discrete levels (e.g. a full, a reduced and a further reduced intensity level) or may vary continuously or incrementally between a maximum and minimum level. The traffic signalling apparatus may be portable, i.e. movable to a location for temporary use.
