Abstract

A system for indicating danger to a vehicle comprises a fixed part on the ground in the form of sensors which are arranged along a traffic lane and which are capable of detecting a vehicle situated in their zones of sensitivity. Such a signal, termed a presence signal, is transmitted to a centralised master control circuit via all the preceding sensors and in each sensor through which it passes it triggers a signal which gives the distance between the vehicule and the sensor. This signal is received by another vehicle situated in the zone of sensitivity of the transmitting sensor. When compared with a signal which indicates a socalled safe distance, the first signal triggers a danger indicator when this is necessary.
