Abstract
A traffic light control system includes at least one parameter and a signal decoding circuit. The parameter or parameters are useful for assisting in differentiating between multiple communication modes. The signal decoding circuit has a front-end circuit and a back-end circuit. The front-end circuit is adapted to receive respective signals transmitted in multiple communication modes. The front-end circuit is adapted to produce data representative of at least a portion of the respective signals. The back-end circuit is adapted to interpret and process the produced data according to at least one of multiple traffic light control protocols respectively associated with the multiple communication modes. The signal decoding circuit is adapted to access said at least one parameter and associate the produced data with one of the multiple communication modes.
Claims (11)
1. A traffic light control system, comprising:
at least one parameter useful for assisting in differentiating between multiple communication modes;
a signal decoding circuit having a front-end circuit adapted to receive respective signals transmitted in multiple communication modes and produce data representative of at least a portion of the respective signals, and a back-end circuit adapted to interpret and process the produced data according to at least one of multiple traffic light control protocols respectively associated with the multiple communication modes; and wherein the signal decoding circuit is adapted to access said at least one parameter and associate the produced data with one of the multiple communication modes.
at least one parameter useful for assisting in differentiating between multiple communication modes;
a signal decoding circuit having a front-end circuit adapted to receive respective signals transmitted in multiple communication modes and produce data representative of at least a portion of the respective signals, and a back-end circuit adapted to interpret and process the produced data according to at least one of multiple traffic light control protocols respectively associated with the multiple communication modes; and wherein the signal decoding circuit is adapted to access said at least one parameter and associate the produced data with one of the multiple communication modes.
2. The traffic light control system of claim 1, wherein the signal decoding circuit is adapted to access and use said at least one parameter before the back-end circuit interprets and processes the produced data.
3. The traffic light control system of claim 1, wherein the back-end circuit is adapted to use said at least one parameter for interpreting and processing the produced data.
4. The traffic light control system of claim 1, wherein the signal decoding circuit is adapted to channel the produced data through a first one of two mode decoding modules, before the other of the two mode decoding modules, to facilitate interpreting the produced data, wherein the two mode decoding modules respectively correspond to two of the multiple communication modes.
5. The traffic light control system of claim 1, wherein the signal decoding circuit includes a circuit adapted to differentiate between the multiple communication modes using said at least one parameter.
6. The traffic light control system of claim 1, wherein the back-end circuit is adapted to log a portion of the produced data and thereby provide access thereto for external display.
7. The traffic light control system of claim 1, wherein the back-end circuit is adapted to validate the produced data according to said at least one of the multiple traffic light control protocols.
8. The traffic light control system of claim 7, wherein said at least one parameter includes multiple tables respectively associated with the multiple communication modes and the back-end circuit is adapted to validate the produced data using one of the multiple tables.
9. The traffic light control system of claim 7, wherein said at least one parameter includes a table containing information associated with each of the multiple communication modes and the back-end circuit validates the produced data using the table.
10. The traffic light control system of claim 1, wherein the back-end circuit includes a processor that accesses a database including said at least one parameter.
11. The traffic light control system of claim 1, wherein said at least one parameter includes at least one table that includes vehicle identification codes for the multiple traffic light control protocols.
