Abstract
1485779 Road-traffic signalling-apparatus THOMSON-CSF 4 Dec 1974 [7 Dec 1973] 52540/74 Heading G4Q A system for indicating danger to a concerned vehicle travelling along a traffic lane A comprises fixed means B associated with A for detecting the presence of vehicles in A, means B for transmitting presence information C, means on vehicles for receiving C and deriving therefrom whether C comes from a vehicle in front of the concerned vehicle, and means for generating a signal when C is a pulse within a length corresponding to a safe distance from the concerned vehicle. In an embodiment a plurality of sensors are distributed along A, a master controller emits synchronizing pulses for triggering the sensors sequentially, means in the sensors for transmitting a presence signal relating to a vehicle in the sensitivity zone of a sensor to the master controller via all preceding sensors in turn, means aboard vehicles for discriminating received presence signals from synchronizing pulses, a "safety pulse" generator for generating a danger signal when the presence signal from a vehicle in front of that concerned is within a distance determined from the vehicle's speed and external conditions, and means for audibly and visibly indicating the danger signal; the concerned vehicle may include an indicator which monitors the reception of the synchronizing pulses. An indication may be given on the concerned vehicle that its speed is too low. Detailed circuitry for achieving the above features is described.
