<p>Traffic regulation system includes a series of light responsive elements (20) spaced at intervals along the track (e.g. road) which respond to vehicle headlights, and a series of light emitter elements (14) also spaced along the track to be visible to operators of approaching vehicles, each light responsive element being connected by fibre optic cabling (22, 24) or other transmitting or transducer means to light emitter elements rearwardly of that particular location so that the light emitting elements along the track are activated sequentially in response to the headlights of a vehicle travelling ahead to provide a visible warning to following vehicles or vehicles on an intersecting course of the presence and distance ahead of the first vehicle. (Fig. 1 is a plan view). Distinct series of emitting elements may be interconnected to provide warning of respective zones of spacing between vehicles following each other, using red and amber light respectively. <IMAGE></p> |
