1. A vehicle navigation system, comprising:
a receiver configured to receive broadcasted information about a measured route of travel; and
a display configured to display at least a portion of the broadcasted information, wherein the broadcasted information is based upon
receiving, from a first camera positioned at a beginning of the measured route of travel, imagery of a plurality of vehicles at a first location,
receiving, from a second camera positioned at an end of the measured route of travel, imagery of a plurality of vehicles at a second location,
individually identifying different vehicles in both the first and second imagery, and
calculating a rate of travel for each of the individually identified vehicles based upon the first imagery and the second imagery.
2. The vehicle navigation system of claim 1, wherein the broadcasted information is further based upon
calculating an elapsed time of travel along the measured route of travel for each of the individually identified vehicles, and
calculating an average rate of travel along the measured route of travel over a predetermined period of time.
3. The vehicle navigation system of claim 1, wherein
the broadcasted information identifies the route of travel and an average rate of travel along the measured route of travel.
4. The vehicle navigation system of claim 3, wherein
the average rate of travel is broadcasted only when the average rate of travel falls below a threshold value.
5. The vehicle navigation system of claim 3, wherein
the average rate of travel is broadcasted to the vehicle navigation system only when a planned route of travel stored in the vehicle navigation system includes the measured route of travel.
6. The vehicle navigation system of claim 3, wherein
the display is configured to display the average rate of travel.
7. The vehicle navigation system of claim 1, wherein
the broadcasted information includes at least one of the first and second locations.
8. The vehicle navigation system of claim 1, wherein
the broadcasted information includes a weather report for the predetermined route of travel.

the predetermined route of travel is along a waterway.
12. A method for receiving broadcasted information about a measured route of travel using vehicle navigation system, comprising:
receiving, using a receiver, the broadcasted information about the measured route of travel; and
displaying, on a display, at least a portion of the broadcasted information, wherein
the broadcasted information is based upon
receiving, from a first camera positioned at a beginning of the measured route of travel, imagery of a plurality of vehicles at a first location,
receiving, from a second camera positioned at an end of the measured route of travel, imagery of a plurality of vehicles at a second location,
individually identifying different vehicles in both the first and second imagery, and
calculating a rate of travel for each of the individually identified vehicles based upon the first imagery and the second imagery.
13. The method of claim 12, wherein
the broadcasted information is further based upon
calculating an elapsed time of travel along the measured route of travel for each of the individually identified vehicles, and
calculating an average rate of travel along the measured route of travel over a predetermined period of time.
14. The method of claim 12, wherein
the broadcasted information identifies the route of travel and an average rate of travel along the measured route of travel.
