Abstract

1311398 Road traffic signals L KAMB 30 Nov 1971 [4 Dec 1970] 55418/71 Heading G4Q In an accident warning system for motorways, posts carrying warning lamps are arranged at intervals along the motorway and each post is provided with a switch which brings into operation the lamps along a predetermined length of motorway in a direction contrary to that of the traffic flow. In the system described, closing of a switch reports the position of an accident to the police, and the posts also carry fog lamps which are operated when necessary by means of a photo-electric switch. In a direct current system, Fig. 2 (not shown), a relay is mounted on each post for switching on the warning light, another relay is used for switching on the fog lamp, and a diode and resistance are provided in the reporting line. The warning lamps may be of the flashing rotating beacon type. Diodes are arranged in lines connecting the warning lights for the unidirectional transmission of current to adjoining warning lamps which glow progressively less brightly and flash at progressively lower frequencies. In an alternating current system, Fig. 3 (not shown), relays and resistances replace the diodes in the lines to adjacent warning lamps. Part of the circuit components may be arranged in a distributer box mounted in a concrete socket a few yards away from the road, safety fuses being provided in all conductors leading from the box.
