Abstract

There is described a monitoring system (1) for monitoring traffic in a highway section, and including at least one detecting unit (2) installed in a sensor vehicle (3) circulating in the highway section to monitor traffic locally; and a remote central operating unit (4) communicating with the detecting unit (2) to receive local monitoring information. The detecting unit (2) includes a locating device (6) supplying information relative to the position of the relative sensor vehicle (3); a sensor device (5) supplying information relative to the position of objects and/or vehicles around the sensor vehicle (3); and a transmitting device (8) for transmitting the information supplied by the locating device (6) and sensor device (5). The remote central operating unit (4) includes a receiving device (9) for receiving the information transmitted by the detecting unit (2); and a processing unit (11, 12) for processing the information.

Claims

1. ) A monitoring system for monitoring traffic in a highway area, comprising:

a detecting unit installed in a sensor vehicle circulating in said highway area to monitor traffic; and

a remote central operating unit communicating with said detecting unit to receive local monitoring information,

said detecting unit comprising

locating means supplying information relating to the position of the sensor vehicle;

sensor means supplying information relating to the position of objects or vehicles around the sensor vehicle; and

transmitting means for transmitting the information supplied by the locating means and the sensor means,

said remote central operating unit comprising receiving means for receiving the information transmitted by the detecting unit, and processing means for processing said information.

2. A monitoring system as claimed in claim 1, wherein the processing means of the remote central operating unit comprise computing means for geographically plotting the information relating to the detected traffic on a geographical map of the monitored highway area.

3. A monitoring system as claimed in claim 2, wherein the processing means of the remote central operating unit comprise checking means for checking the traffic situation on said geographical map to indicate anomalous or road hazard conditions.

4. A monitoring system as claimed in claim 2, wherein the computing means enter on the geographical map information relating to the position, movement and speed of each object or vehicle detected by the sensor means.

5. A monitoring system as claimed in claim 1, wherein the sensor means comprise radar means for supplying information concerning the position of objects and/or vehicles in the highway area ahead of the sensor vehicle.

6. A monitoring system as claimed in claim 5, wherein the computing means enter on the geographical map information relating to the position, movement and speed of each object or vehicle detected by the sensor means.

7. A monitoring system as claimed in claim 1, wherein the locating means comprise GPS receiving means.

8. A monitoring system as claimed in claim 1, wherein the detecting unit comprises processing means for processing said information to supply, via a signalling device, an audio or visual alarm signal to warn a user of the sensor vehicle of a predetermined anomalous road situation.

9. A monitoring system as claimed in claim 1, wherein the remote central operating unit comprises transmitting means for transmitting information concerning the monitored traffic situation to vehicles circulating in the highway area.

10. A sensor vehicle for a traffic monitoring system as claimed in claim 1.

11. A sensor vehicle for a traffic monitoring system, said sensor vehicle having a detecting unit comprising:

locating means supplying information relating to the position of the sensor vehicle;

sensor means supplying information relating to the position of objects or vehicles around the sensor vehicle; and

transmitting means for transmitting the information supplied by the locating means and the sensor means to a remote central operating unit of said system.
