Abstract

1436258 Road-traffic signalling-apparatus P E TUFFET 17 July 1973 [17 July 1972] 34010/73 Heading G4Q In a system for alerting the driver of a vehicle to the approach of a road sign, hazard or speed restriction two magnets are placed across the whole width of the roadway 1 (41, 42, Fig. 2, not shown) and so oriented as to present predetermined magnetic poles to a vehicle approaching from a given direction; in the vehicle a detector 5 supplies electric pulses to a control circuit 7 as the vehicle passes over the magnets, the control circuit incorporating gating means such that an audible and/or visual warning 13, 14 is given in the vehicle only when the predetermined poles are encountered from the given direction. Thus a vehicle travelling away from the road sign &c. does not respond but an overtaking vehicle travelling towards the road sign &c. does respond. The warning may be stopped by a button 16. For warning of a speed restriction the separation of the magnets is made to correspond thereto.
