Definitions

  • the present invention relates to vehicle guidance and proximity warning systems for use, particularly, on vehicle trackways such as motorways and similar roads.
  • Motorways and similar roads are generally considered to be the safest form of roads.
  • accidents which do occur thereon typically involve a plurality of vehicles.
  • Serious accidents involving many vehicles are most likely to occur in foggy conditions.
  • foggy conditions even with modern increased intensity rear lighting systems, drivers often become aware of traffic ahead of them at a time when they are closing on that traffic at a speed too great to allow a collision to be avoided.
  • a possible contributory factor towards excessive speeds is that in foggy conditions motorways provide very few visual references to give a driver a subjective impression of speed under conditions when the diversion of attention from outside a vehicle to the instruments ia inadvisable.
  • a vehicle guidance or proximity warning system includes at least one series of light receivers and at least one series of light transmitters, both series being fixed relative to a vehicle trackway, in which each receiver is arranged to react to light from a vehicle headlight such as to cause at least one transmitter spaced apart from the receiver to transmit light.
  • Each series is preferably embedded in a road surface parallel to a road centre line, and preferably form a single line. Alternatively one or both series can be positioned at the side of a road.
  • transmitters forward of a direction of vehicle motion are caused to transmit light.
  • transmitters rearward of a direction of vehicle motion are caused to transmit light, and in this case light transmitters are preferably adapted to transmit light in the red spectrum range.
  • a light receiver and a light transmitter are housed in a common unit, preferably of the "cats eyes",type which can advantageously also house a conventional "cats eye” reflector.
  • each light receiver is connected by a fibre optic cable to a single light transmitter.
  • each light receiver may communicate with an actuator whereby light from a powered light source is supplied to an associated transmitter.
  • this powered light units are preferably sited at the side of the roadway with light being communicated thereto and therefrom via fibre optic cables.
  • Figure 1 is an elevation, partly in section, of a road fitted with a vehicle proximity warning system according to the invention
  • Figure 2 is a perspective view of a light unit as used in Figure 1
  • FIGS 3 and 4 are details of the unit shown in Figure 2.
  • a road 10 ( Figure 1 ) has embedded in its surface a plurality of units such as those shown at 11.
  • Each unit 11 ( Figure 2) comprises a housing in the form of a block 12 of rubber or similar material which is adapted to retract into the road surface (in a manner well-known in th art) when contacted by a wheel of a vehicle.
  • a receiving lens 13 and a transmitting lens 15 connected to fibre optic cables 14, and a reflector 16.
  • a red filter 17 ( Figure 3) whilst the receiver 13 is connected directly to the fibre optic cable 14 ( Figure 4).
  • the fibre optic cable 14 of each receiving lens 13 is connected ( Figure 1) to the transmitting lens 15 of a rearward (relative to intended direction of vehicle flow along the road 10) unit 11.
  • each receiving lens is connected to at least one forwardly positioned and at least one rearwardly positioned transmitting lens.
  • transmitters or both can be situated at the side of a road.

Abstract

Les phares d'un véhicule (20), éclairant successivement une série de récepteurs lumineux (13) fixés par rapport à une route (10), éclairent successivement une série d'émetteurs lumineux (15) également fixés par rapport à cette route (10), à l'avant du véhicule (20) pour lui servir de guide, par exemple dans les virages, ou à l'arrière du véhicule (20) pour avertir les véhicules suiveurs de sa présence dans des conditions de mauvaise visibilité. La lumière (21) arrivant sur les récepteurs (13) est transmise le long de câbles à fibres optiques (14), de préférence directement vers les émetteurs (15); dans un autre mode de réalisation, cette lumière (21) peut activer des sources lumineuses placées sur les côtés de la route, afin d'éclairer les émetteurs (15) par l'intermédiaire de câbles à fibres optiques (14). Le récepteur lumineux (13) et l'émetteur lumineux (15) peuvent être logés dans une unité commune (11), constituée par exemple par un bloc (12) indiquant la surface de la route, qui comprend un réflecteur reflex (16) et qui peut être enfoncé dans le revêtement de la route.
