Vehicle traffic flow data acquisition and distribution
View Patent ↗Embodiments of the present invention provide a method, system and computer program product for vehicle traffic flow data acquisition and reporting for onboard vehicle navigation. In an embodiment of the invention, a method for vehicle traffic flow data acquisition and reporting for onboard vehicle navigation can include acquiring imagery of multiple vehicles traveling on a roadway between two locations and individually identifying the different vehicles in the imagery. An elapsed time of travel can be determined for the individually identified vehicles between the two locations and a rate of travel can be computed for each of the individually identified different vehicles based upon the elapsed time of travel. Thereafter, the rate of travel for at least one of the individually identified different vehicles can be broadcast to a subscriber for at least one of the two locations.
1. A data acquisition and distribution hardware system for distributing information about a measured route of travel, comprising:
an image detection hardware system configured to:
receive, from a first camera positioned at a beginning of the measured route of travel, imagery of a plurality of vehicles at a first location,
receive, 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 identify different vehicles in both the first and second imagery,
calculate a rate of travel for each of the individually identified vehicles based upon the first imagery and the second imagery; and
a broadcasting system configured to:
broadcast information about the measured route of travel to an onboard vehicle navigation system of a subscriber.
2. The hardware system of claim 1 , wherein
the image detection hardware system is further configured to:
calculate an elapsed time of travel along the measured route of travel for each of the individually identified vehicles, and
calculate an average rate of travel along the measured route of travel over a predetermined period of time.
3. The hardware system of claim 1 , wherein
the information identifies the route of travel and an average rate of travel along the measured route of travel.
4. The hardware system of claim 3 , wherein
the average rate of travel is broadcast only when the average rate of travel falls below a threshold value.
5. The hardware system of claim 3 , wherein
the average rate of travel is broadcast to the subscriber only when a subscriber-planned route of travel in the onboard navigation system includes the measured route of travel.
6. The hardware system of claim 3 , wherein
the average rate of travel is displayed on the onboard vehicle navigation system of the subscriber.
7. The hardware system of claim 1 , wherein
the information includes at least one of the first and second locations.
8. The hardware system of claim 1 , wherein
the information includes a weather report for the predetermined route of travel.
9. The hardware system of claim 1 , wherein
the broadcasting system uses one of text messaging and e-mail to broadcast the information to the onboard vehicle navigation system.
10. The hardware system of claim 1 , wherein
the predetermined route of travel is along a roadway.
11. The hardware system of claim 1 , wherein
the predetermined route of travel is along a waterway.
12. A method for distributing information about a measured route of travel using a data acquisition and distribution hardware system, comprising:
receive, 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,
calculating a rate of travel for each of the individually identified vehicles based upon the first imagery and the second imagery; and
broadcasting information about the measured route of travel to an onboard vehicle navigation system of a subscriber.
13. The method of claim 12 , further comprising
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 information identifies the route of travel and an average rate of travel along the measured route of travel.
15. The method of claim 14 , wherein
the average rate of travel is broadcast only when the average rate of travel falls below a threshold value.
16. The method of claim 14 , wherein
the average rate of travel is broadcast to the subscriber only when a subscriber-planned route of travel in the onboard navigation system includes the measured route of travel.
17. The method of claim 14 , wherein
the average rate of travel is displayed on the onboard vehicle navigation system of the subscriber.
18. The method of claim 12 , wherein
the information includes at least one of the first and second locations.
19. The method of claim 12 , wherein
the information includes a weather report for the predetermined route of travel.
20. The method of claim 12 , wherein
the information is broadcast to the onboard vehicle navigation system using one of text messaging and e-mail.
21. The method of claim 12 , wherein
the predetermined route of travel is along a roadway.
22. The method of claim 12 , wherein
the predetermined route of travel is along a waterway.
