Abstract

An automatic vehicle identification (AVI) unit includes a transponder to communicate with an interrogator regarding at least an identification of a vehicle in which the AVI unit is located, and an audio speaker to broadcast verbal announcements based on information received from the interrogator. A highway monitoring and broadcast system includes means to collect and analyze activity on the highway and to determine when such activity requires sending information to vehicles on the highway, and an interrogator to communicate with AVI transponders installed in the vehicles.

Claims

1. An automatic vehicle identification (AVI) unit comprising:

a transponder to communicate with an interrogator regarding at least an identification of a vehicle in which said AVI unit is located, wherein said transponder has standby and active modes, wherein when in said standby mode said transponder sends an identification signal upon receipt of an identification request from said interrogator, and when in said active mode said transponder receives commands from said interrogator; and

an audio speaker to broadcast verbal announcements based on information received from said interrogator.

2. The AVI unit according to claim 1 and also comprising:

a translator module to translate said information to said announcements as per a list of said commands and associated said verbal announcements.

3. The AVI according to claim 2 and wherein said translator module comprises at least one of:

a command translator to translate system commands to pre-recorded audio announcements, and a text to speech translator to generate new audio announcements.

4. The AVI unit according to claim 1 and where said verbal announcements relay information regarding at least one of:

road status, speed limitations, weather conditions and reminders.

5. The AVI unit according to claim 1 and where said verbal announcements are relevant to a current location of said vehicle.

6. The AVI unit according to claim 1 and wherein said interrogator is part of a highway monitoring system.

7. The unit according to claim 6 and wherein said highway is a toll highway.

8. The AVI unit according to claim 1 and wherein said interrogator is part of at least one of a weigh in motion (WIM) application, access control and management system, traffic management probe, and a location based service.

9. The unit according to claim 1 and wherein the transponder is an electronic card located within a closed casing.

10. The unit according to claim 1 and wherein said verbal announcements pertain to a current location of said vehicle.

11. A highway monitoring and broadcast system comprising:

means to collect and analyze activity on said highway and to determine when such activity requires sending information to vehicles on said highway; and

an interrogator to communicate with AVI transponders installed in said vehicles, wherein said transponders have standby and active modes, wherein when in said standby mode said transponders send identification signals upon receipt of an identification request from said interrogator, and when in said active mode said transponders receive commands from said interrogator.

12. The system according to claim 11 and wherein said means comprise an interface with at least one of a real-time traffic information system and a weather reporting system.

13. The system according to claim 11 and wherein said highway is a toll highway and said interrogators comprise means to receive said identification signals from said AVI transponders, said identification signals being suitable for billing purposes.

14. The system according to claim 11 and wherein said interrogator comprises means to at least forward information to said vehicles, said information regarding at least one of road status, speed limitations, weather conditions and reminders.

15. The system according to claim 14 and wherein said information is relevant to a current location of said vehicles.

16. The system according to claim 11 and wherein said interrogator is part of at least one of a weigh in motion (WIM) application, access control and management system, traffic management probe, and a location based service.
