Traffic Data Encoding Using Fixed References
First Claim
Patent Images
1. A computer-implemented method of encoding traffic data, the method comprising:
- at a computing device having a data processor and computer memory;
matching a set of fixed locations along a roadbed to a target map;
generating flow vectors representing traffic data using the fixed locations of the target map; and
;
delivering the generated flow vectors to a receiver to enable the receiver to render the represented traffic data based on the generated flow vectors.

Abstract
A method is provided for encoding traffic incident and flow data using target map locations, such as OpenStreetMap (OSM) locations directly, rather than going through a conversion stage. In exemplary embodiments, the method can include selecting a set of fixed, identifiable locations along a roadbed, matching these to a target map, generating flow vectors in the target map'"'"'s referencing model, and deliver only target map location data to the external application. Non-point location data such as incidents can also be represented using the same scheme, using an offset along a previously defined path for the start and end points.
