Abstract

The invention relates to methods and apparatus for displaying toll charging parameters of vehicles by means of a roadside display. In one embodiment, parameters are sent from an onboard-unit of the vehicle to the roadside display. In an alternative embodiment, parameters are registered under a vehicle identification in a database and retrieved therefrom for displaying on the roadside display by a detection of the identification of the vehicle.

Claims

1. A method of displaying toll charging parameters set in a toll charging electronic onboard-unit provided in a vehicle, the method comprising:

sending, using the electronic onboard-unit, at least one toll charging parameter from the electronic onboard-unit to an automated, publically viewable roadside display monitor; and

displaying said at least one parameter on the roadside display monitor, wherein said parameter is a numeric value representing a count of the number of occupants of the vehicle, said at least one parameter on the roadside display monitor being visible to an occupant of the vehicle, enforcement officers, other drivers and passers-by.

2. The method of claim 1, wherein the vehicle is traveling on a high-occupancy or express toll lane, and wherein the roadside display monitor comprises a large sign for displaying the toll charging parameters.

3. The method of claim 1, wherein said parameter includes a vehicle class of the vehicle.

4. The method of claim 1, wherein said parameter includes a status of the vehicle registered in a database list.

5. The method of claim 1, wherein the sending step is made using a DSRC, WAVE, RFID or infrared link.

6. An apparatus for displaying toll charging parameters set in a toll charging onboard-unit of a vehicle comprising:

at least one onboard-unit including means for sending at least one of its toll charging parameters to at least one publically viewable roadside display monitor;

wherein the at least one roadside display monitor includes means for receiving and displaying said parameter thereon, wherein said parameter is a numeric value representing a count of the number of occupants of the vehicle, said parameter on the roadside display monitor being visible to an occupant of the vehicle, enforcement officers, other drivers and passers-by.

7. The apparatus of claim 6, wherein the vehicle is traveling on a high-occupancy or express toll lane, and wherein the roadside display monitor comprises a large sign for displaying the toll charging parameters.

8. The apparatus of claim 6, wherein said parameter includes a vehicle class of the vehicle.

9. The apparatus of claim 6, wherein the means for sending and the means for receiving said parameter is a DSRC, WAVE, RFID or infrared link established between the onboard-unit and the roadside display.

10. A method of displaying toll charging parameters of a vehicle comprising:

registering at least one toll charging parameter of the vehicle together with an identification of the vehicle in a database,

detecting the identification of a vehicle and automatically sending said identification using a first electronic device to the database,

retrieving at least one toll charging parameter for said identification from the database and automatically sending said at least one toll charging parameter using a second electronic device to a publically viewable roadside display monitor, and

displaying said at least one parameter on the roadside display monitor, wherein said at least one parameter is a numeric value representing a count of the number of occupants of the vehicle, said at least one parameter on the roadside display monitor being visible to an occupant of the vehicle, enforcement officers, other drivers and passers-by.

11. The method of claim 10, wherein said identification is written on a license plate of the vehicle and said detecting step is made by optical reading of the license plate.

12. The method of claim 10, wherein said identification is stored in an electronic device of the vehicle and said detecting step is made by wireless communication with the electronic device.

13. The method of claim 12, wherein said detecting step is made using a DSRC, WAVE, RFID, or infrared link.

14. The method of claim 10, wherein said registering step is made by means of a web portal of the database server.

15. The method of claim 10, wherein said registering step is made by means of a short message sent to the database server via a mobile phone network.

16. The method of claim 10, wherein said parameter includes a vehicle class of the vehicle.

17. An apparatus for displaying toll charging parameters of a vehicle, comprising:

a database for registering at least one toll charging parameter of the vehicle together with an identification of the vehicle,

a detection and retrieval device for detecting the identification of a vehicle and retrieving at least one of the toll charging parameters registered under this identification from the database, and

a publically viewable roadside display monitor for displaying said at least one parameter retrieved, wherein said at least one parameter is a numeric value representing a count of the number of occupants of the vehicle, said at least one parameter on the roadside display monitor being visible to an occupant of the vehicle, enforcement officers, other drivers and passers-bv.

18. The apparatus of claim 17, wherein said detection and retrieval device comprises a camera reading a license plate of the vehicle as said identification.

19. The apparatus of claim 17, wherein said detection and retrieval device comprises a wireless communication device reading an electronic identification tag of the vehicle as said identification.

20. The apparatus of claim 19, wherein said wireless communication device establishes a DSRC, WAVE, RFID, or infrared link with the electronic identification tag.

21. The apparatus of claim 17, wherein said database has an internet interface for entering registration data.

22. The apparatus of claim 17, wherein said database has a mobile phone network interface for receiving registration data sent by a short message over the mobile phone network.
