Abstract: Vehicles traveling along a predetermined route are equipped with mobile receivers picking up traffic information from a radiating transmission line extending along the route, this information being modulated upon a first carrier F1 for vehicles traveling in one direction and upon a second carrier F2 for vehicles traveling in the opposite direction. Two ancillary short-range transmission stations, located at opposite ends of the line, radiate amplitude-modulated carrier waves directly to vehicles in the vicinity thereof whose receivers are tuned to either of the two carriers F1, F2. The first ancillary station emits the two carriers both modulated with a low-frequency signal f1 whereas the second ancillary station emits the same carriers modulated with a different low-frequency signal f2. A discriminating circuit aboard each vehicle, upon the reception of an amplitudemodulated carrier, tunes the receiver thereof either to the carrier F1 in response to a detected signal f1 or to the carrier F2 in response to a detected signal f2.

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.

Abstract: A system for the surveillance of a route along which vehicles are moving, and which operates in real time, comprises radar equipment whose transmitter and receiver are each connected to a leak line acting as an antenna for respectively transmitting outgoing energy from the radar unit and conveying reflected energy back to the radar unit. These lines are mutually decoupled so that only the line connected to the receiver picks up the energy reflected by a moving object or a fixed obstacle situated on the surveyed route.

Abstract: A system for the surveillance in localized areas of objects moving along a route is described which includes detectors distributed along the route to be kept under surveillance; each of these detectors is connected by a multi-core cable to a control post which individually interrogates the detectors and processes the information supplied by them.

Abstract: A route or a section thereof is monitored by sensors distributed therealong which are identical and are triggered sequentially one from another after a certain delay in each case, the first of these sensors being triggered by a master pulse. The responses from the sensors which indicate the presence of a vehicle are retransmitted to a control device through the preceding sensors. The sensors comprise each a miniature transmitter and a miniature receiver which are slightly coupled to each other when in operation, the coupling being intensified in the presence of a vehicle in the operating zone of a sensor.
