Abstract

Data acquisition from a sampling of vehicle sensors includes identifying a vehicle population density for a defined region, calculating a proportional representation ratio from the vehicle population density, and transmitting a request for data over a network. The request includes the response criteria configured with the proportional representation ratio. The data acquisition also includes receiving the data from vehicles that are located in the defined region and that fall within the proportional representation ratio, and which meet the response criteria.

Claims

1. A system for data acquisition from a sampling of vehicle sensors, comprising:

a host system computer; and

logic executable by the host system computer, the logic configured to implement a method, the method comprising;

identifying a vehicle population density for a defined region;

calculating a proportional representation ratio from the vehicle population density;

transmitting a request for the data over a network, the request including response criteria configured with the proportional representation ratio; and

receiving the data from vehicles that are located in the defined region and that fall within the proportional representation ratio, and which meet the response criteria.

2. The system of claim 1, wherein the vehicle population density is calculated by at least one of previously transmitted responses to requests for the data, and a number of roads in the defined region.

3. The system of claim 1, wherein the proportional representation ratio is a function of an anticipated volume of vehicles in the defined region at a point in time.

4. The system of claim 1, wherein the request for the data is transmitted to vehicles over a radio data system protocol-enabled broadcast network, and the response criteria is used to filter a number of the vehicles for responding to the request.

5. The system of claim 1, wherein the response criteria is configured to use a vehicle identification number to identify the vehicles from which the data is received.

6. The system of claim 1, wherein the request for the data is periodically transmitted.

7. The system of claim 1, wherein the request for the data is transmitted upon an occurrence of a condition detected in the defined region.

8. The system of claim 1, wherein the data subject to the request includes at least one of:

temperature;

vehicle speed;

vehicle volume;

vehicle occupancy;

windshield wiper usage;

radio usage;

lane occupancy;

toll collection information;

freight tracking information;

weather conditions; and

roadway conditions.

9. A method for data acquisition from a sampling of vehicle sensors, comprising:

identifying a vehicle population density for a defined region;

calculating a proportional representation ratio from the vehicle population density;

transmitting a request for data over a network, the request including response criteria configured with the proportional representation ratio; and

receiving the data from vehicles that are located in the defined region and that fall within the proportional representation ratio, and which meet the response criteria.

10. The method of claim 9, wherein the vehicle population density is calculated by at least one of previously transmitted responses to requests for the data, and a number of roads in the defined region.

11. The method of claim 9, wherein the proportional representation ratio is a function of an anticipated volume of vehicles in the defined region at a point in time.

12. The method of claim 9, wherein the request for the data is transmitted to vehicles over a radio data system protocol-enabled broadcast network, and the response criteria is used to filter a number of the vehicles for responding to the request.

13. The method of claim 9, wherein the response criteria is configured to use a vehicle identification number to identify the vehicles from which the data is received.

14. The method of claim 9, wherein the request for the data is periodically transmitted.

15. The method of claim 9, wherein the request for the data is transmitted upon an occurrence of a condition detected in the defined region.

16. The method of claim 9, wherein the data subject to the request includes at least one of:

temperature;

vehicle speed;

vehicle volume;

vehicle occupancy;

windshield wiper usage;

radio usage;

lane occupancy;

toll collection information;

freight tracking information;

weather conditions; and

roadway conditions.

17. A computer program product for implementing data acquisition from a sampling of vehicle sensors, the computer program product comprising a computer storage medium having instructions embodied thereon, which when executed by a computer cause the computer to implement a method, the method comprising:

identifying a vehicle population density for a defined region;

calculating a proportional representation ratio from the vehicle population density;

transmitting a request for the data over a network, the request including response criteria configured with the proportional representation ratio; and

receiving the data from vehicles that are located in the defined region and that fall within the proportional representation ratio, and which meet the response criteria.

18. The computer program product of claim 17, wherein the vehicle population density is calculated by at least one of previously transmitted responses to requests for the data, and a number of roads in the defined region.

19. The computer program product of claim 17, wherein the proportional representation ratio is a function of an anticipated volume of vehicles in the defined region at a point in time.

20. The computer program product of claim 17, wherein the request for the data is transmitted to vehicles over a radio data system protocol-enabled broadcast network, and the response criteria is used to filter a number of the vehicles for responding to the request.
