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.
