Abstract

An Enhanced Traffic Sign Information Messaging System (ETSIMS) that provides the methodology, functions and support equipment to provide vehicles, which might not be within sight of the traffic message sign, with all or some prioritized parts of the message displayed on the sign, or an enhanced version of the information provided on the sign, including traffic information messages inferred from the message displayed on the traffic message sign. ETSIMS may also provide messages of this type without the need for the physical presence of a sign on the roadway.

Claims

1. A method for receiving traffic messages or message components from a management center and providing them to a vehicle operator or controls of automated vehicles comprising:

a. receiving a traffic message or message components from the management center;

b. limiting the traffic message or the message components to a total length that is safe and consistent with vehicle display constraints for motorist display purposes;

c. limiting the traffic message or the message components to a physical size of the vehicle display; and

d. providing the traffic message or the message components on the vehicle display or to controls of an automated vehicle.

2. The method of claim 1, further comprising providing an option for the vehicle operator to display the traffic message or the message components according to the vehicle operator'"'"'s message style preferences to avoid the vehicle operator'"'"'s distraction.

3. The method of claim 2, wherein the option for the vehicle operator to display the traffic message or the message components according to the vehicle operator'"'"'s message style preferences is facilitated by a mode selection process.

4. The method of claim 3, wherein the mode selection process comprises an automatic mode and a manual mode for the vehicle operator to review, accept, reject or modify the traffic message or the message components.

5. The method of claim 1, further comprising assigning a priority level for the traffic message or the message components to enable limiting the traffic message or the message components to the physical size of the vehicle display.

6. The method of claim 5, wherein the step of providing the traffic message or the message components is based on the priority level.

7. The method of claim 5, wherein the priority level is selected based on a severity of an event, an impact of the event, or on a proximity of the event to the vehicle.

8. The method of claim 1, further comprising identifying the message components after receiving the message components from the management center.

9. The method of claim 8, wherein the step of identifying the message components is performed using keywords or other artificial intelligence techniques.

10. The message of claim 1, wherein the limiting the total length of the traffic message or the message components is limited to two seconds in duration.

11. A method for providing inferred traffic information messages, comprising:

a. receiving a message displayed on a pseudo DMS or a pseudo ADMS at a management center from a traffic management center (TMC), a regional traffic information center or a traffic information service;

b. associating a first at least one catchment domain including one or more parts of a roadway network and a management domain including one or more parts of the roadway network with the pseudo DMS or the pseudo ADMS;

c. identifying keywords present in the message;

d. analyzing the message by message components using the keywords or other techniques;

e. classifying the message components by informational event categories;

f. identifying roadway links for which the message applies using the keywords and a link identifier table;

g. identifying the management domain in which the links are located;

h. identifying a second at least one catchment domain associated with the management domain;

i. searching a plurality of databases for additional message components for each of the informational event categories;

j. generating analyzed database data corresponding to the additional message components;

k. generating inferred enhanced messages as appropriate based on the analyzed database data; and

l. transmitting the inferred enhanced messages to vehicles.

12. The method of claim 11, further comprising assigning a priority level to each of the inferred enhanced messages.

13. The method of claim 12, wherein the step of transmitting the inferred enhanced messages to vehicles is based on the informational event categories and the priority level.

14. The method of claim 11, further comprising processing inferred enhanced messages to generate corresponding processed inferred enhanced messages for presentation in the vehicle.

15. The method of claim 11, wherein the step of generating inferred enhanced messages is performed at a processing center.

16. The method of claim 11, further comprising limiting a size of the inferred enhanced messages to be displayed in the vehicle.

17. The method of claim 11, further comprising providing a geographical data structure that correlates the pseudo DMS or the pseudo ADMS to the management domain and to the first at least one catchment domain.

18. An Enhanced Traffic Sign Information Messaging System, comprising:

a. an interface for receiving at an ETSIMS management center at a physical location or in a cloud at least one message displayed on a pseudo DMS or a pseudo ADMS, said at least one message originating from a traffic management center (TMC), a regional traffic information management center or a traffic information service;

b. a processor coupled to the interface, wherein the processor receives the at least one message through the interface, associates a first at least one catchment domain including one or more parts of a roadway network and a management domain including one or more parts of a roadway network containing a location in the roadway network of the pseudo DMS or the pseudo ADMS, and transmits the at least one message to one or more vehicles.

19. The Enhanced Traffic Sign Information Messaging System of claim 18, wherein the processor processes the at least one message using one or more processing module, selected from the group consisting of prioritizing the at least one message, identifying keywords present in the at least one message, analyzing the at least one message by message components using keywords or other techniques, classifying the at least one message or the components by informational event categories, identifying roadway links for which the at least one message applies using the keywords and a link identifier table, identifying the management domain in which the links are located, identifying a second at least one catchment domain associated with the management domain, searching a plurality of databases for additional message components for each of the informational event categories, generating analyzed database data corresponding to the additional message components, and generating inferred enhanced messages based on the analyzed database data, said one or more processing module operatively coupled to the processor for developing enhanced traffic messages.

20. The Enhanced Traffic Sign Information Messaging System of claim 19, wherein the processor transmits the at least one message to the one or more vehicles based on proximity of the one or more vehicles to the location of the pseudo DMS or the pseudo ADMS in the roadway network.
