Abstract

Systems and methods for information filtering in a roadway travel data exchange network are disclosed. In one embodiment, a travel data processing system may comprise, for example, a communication network. A mobile device may be communicatively coupled to the communication network. A collection system may collect first travel data, where the first travel data may comprise second travel data that is relevant to the mobile device. A filter system may analyze the first travel data to control the flow of at least a portion of the second travel data. A filter device may be communicatively coupled to the communication network and the filter device may comprise at least a portion of the filter system. The mobile device may comprise at least a portion of the filter system.

Claims

1. A travel data processing system, comprising:

a collection system configured to collect travel data associated with at least one mobile device that is communicatively coupled to a communication network; and

a filter system configured to assign at least one weight to the collected travel data and generate filtered travel data that is relevant to the at least one mobile device by discarding at least a portion of the collected travel data, the generating of the filtered travel data based on the at least one weight assigned to the collected travel data.

2. The travel data processing system of claim 1, wherein the filter system comprises at least one filter device communicatively coupled to the communication network.

3. The travel data processing system of claim 1, wherein the at least one mobile device is a part of the filter system.

4. The travel data processing system of claim 1, wherein the filter system controls the flow of the filtered travel data based on analysis of the collected travel data.

5. The system of claim 1, wherein the filter system uses known roadway information.

6. The travel data processing system of claim 1, wherein the filter system uses pedestrian velocity estimates to generate the filtered travel data.

7. The travel data processing system of claim 1, wherein the filter system filters out undesired travel data to generate the filtered travel data.

8. The travel data processing system of claim 7, wherein the filter system filters out the undesired travel data based on the at least one weight value assigned to the collected travel data.

9. The travel data processing system of claim 1, wherein the filtering system filters the collected travel data based on at least one filtering criteria.

10. The travel data processing system of claim 1, wherein the filtering system extrapolates at least a part of the collected travel data to generate the filtered travel data.

11. The travel data processing system of claim 1, wherein the collection system collects the travel data at predetermined intervals.
