Enhanced traffic sign information messaging system
First Claim
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.

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.

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. - View Dependent Claims (12, 13, 14, 15, 16, 17)

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. - View Dependent Claims (19, 20)
