Abstract

A traffic monitoring system includes one or more processors operable to collect location data from a third-party network having a mobile user, weight at least one element of the location data based on reliability, and generate traffic speed data at a roadway location based on the weighted data. The third-party network is one of a mobile communication network, a computer network, a television network, a radio network, and a road sign display network. The one or more processors are operable to deliver the traffic speed data at the roadway location to an alternate third-party network. The alternate third-party network is one of a mobile communication network, a computer network, a television network, a radio network, and a road sign display network.

Claims

1. A traffic monitoring system, comprising:

one or more processors configured to;

collect travel data from at least one mobile device in a third-party network;

weight at least one element of the travel data based on a proximity of the at least one mobile device to a boundary of a roadway; and

generate traffic speed data at a roadway location based on the weighted data.

2. The traffic monitoring system of claim 1, wherein the third-party network is one of a mobile communication network, a computer network, a television network, a radio network, and a road sign display network.

3. The traffic monitoring system of claim 1, wherein the one or more processors are further configured to deliver the traffic speed data at the roadway location to an alternate third-party network.

4. The traffic monitoring system of claim 3, wherein the alternate third-party network is one of a mobile communication network, a computer network, a television network, a radio network, and a road sign display network.

5. The traffic monitoring system of claim 1, wherein the one or more processors are configured to generate the traffic speed data by filtering the travel data.

6. The traffic monitoring system of claim 5, wherein the filtering of the travel data is based on the weighted data.

7. The traffic monitoring system of claim 1, wherein the one or more processors are configured to generate the traffic speed data by discarding at least a portion of the travel data.

8. The traffic monitoring system of claim 1, wherein a lesser weight is assigned to the at least one element of the travel data when the at least one mobile device is within a distance from the boundary of the roadway, and wherein the at least one element of the travel data is assigned a greater weight when the at least one mobile device is outside the distance from the boundary of the roadway.

9. A method for monitoring traffic, the method comprising:

collecting, by one or more processors and/or circuits, travel data from at least one mobile device in a third-party network;

weighting. by the one or more processors and/or circuits, at least one element of the travel data based on a proximity of the at least one mobile device to a boundary of a roadway; and

generating, by the one or more processors and/or circuits, traffic speed data at a roadway location based on the weighted data.

10. The method according to claim 9, wherein the third-party network is one of a mobile communication network, a computer network, a television network, a radio network, and a road sign display network.

11. The method according to claim 9, comprising delivering the traffic speed data at the roadway location to an alternate third-party network.

12. The method according to claim 11, wherein the alternate third-party network is one of a mobile communication network, a computer network, a television network, a radio network, and a road sign display network.

13. The method according to claim 9, comprising generating the traffic speed data by filtering the travel data.

14. The method according to claim 13, wherein the filtering of the travel data is based on the weighted data.

15. The method according to claim 9, comprising generating the traffic speed data by discarding at least a portion of the travel data.

16. The method according to claim 9, further comprising:

assigning a lesser weight to the at least one element of the travel data when the at least one mobile device is within a distance from the boundary of the roadway; and

assigning a greater weight to the at least one element of the travel data when the at least one mobile device is outside the distance from the boundary of the roadway.
