Definitions

  • the invention relates to a fog warning device for roads, in particular highways, with along the roadside arranged optical warning signalers.

  • This results in a particularly effective fog warning device whereby the fact that the optical warning signalers are connected to at least one fog detector via control line or wireless, an automatic activation takes place as soon as the fog detector the presence of fog and therefore a strong conveyeinsehränkung is detected.
  • the control takes place in such a way that a large number of the optical warning signal transmitters arranged along the roadside are switched on, which are located in a region in front of the respective fog detector, which permits a timely reduction in the driving speed, taking into account the required reaction time and the required braking distance.
  • the activation of those warning signal generator is required, which are located at least 1 km from the respective fog front.
  • the activation can take place here in an area of several kilometers in length, since consideration should also be given to a corresponding backwater as a result of the mist.
  • the fog warning device according to the invention if any, provides a significantly improved signal effect, since the signals represent an eye-catcher due to their unusual placement and are certainly located in the field of vision of the driver.

  • the optical warning signal transmitters are arranged along both road edges. This results in a warning not only from the right side of the road, to which traffic signs, signs or warning signals are usually attached, but also from the left edge of the road, where it was often impossible due to the limited Plazttechnik set up the proposed in the prior art warning devices. In particular, vehicles on the left lane continue to move at high or excessive speed and it is therefore particularly important that these drivers are warned by unmistakable signals accordingly in order to reduce their speed in time.
