Abstract

An exemplary method provides-base traffic control (rbtc) information. A network node receives a request generated by a user'"'"'s electronic device for the rbtc information, where the request includes location data. The network node determines a roadway associated with the location data. A database is queried for rbtc information relevent to the roadway and a position on the roadway associated with the location data. A reply is received to the query where the reply contains relevant rbtc information. The relevant rbtc information is transmitted from the network node to the user'"'"'s device.

Claims

1. A method for providing road-based traffic control (rbtc) information comprising the steps of:

receiving at a network node a request generated by a user'"'"'s electronic device for the rbtc information, where the request includes location data;

determining at the network node a roadway associated with the location data;

querying a database for rbtc information relevant to the roadway and a position on the roadway associated with the location data;

receiving a reply to the query where the reply contains relevant rbtc information;

transmitting the relevant rbtc information from the network node to the user'"'"'s device;

wherein the step of transmitting comprises transmitting a speed limit of the roadway at the position.

2. The method of claim 1 wherein the step of receiving the request comprises receiving the request generated by a user'"'"'s wireless electronic device.

3. The method of claim 1 wherein the step of determining comprises parsing the request to identify roadway information transmitted from the user'"'"'s electronic device.

4. The method of claim 1 wherein the step of determining comprises transmitting a query containing the location data to a database containing roadway information that can be accessed based on location data, and receiving a reply in response to the query where the reply contains an identified roadway corresponding to the location data.

7. The method of claim 1 wherein the network node comprises a web site and the user'"'"'s electronic device comprises a wireless electronic device, communications between the wireless electronic device and the network node being supported by a communication system.

8. The method of claim 1 wherein the user'"'"'s electronic device is a wireless electronic device disposed in a vehicle traveling along the roadway.

12. The method of claim 1 wherein said speed limit of the roadway is a posted speed limit.
