Method and apparatus for determining split lane traffic conditions utilizing both multimedia data and probe data
First Claim
1. A navigation system comprising:
- a communication interface configured to receive multimedia data including one or more images from a camera representative of traffic conditions along a road segment upstream of a junction; and
at least one processor configured to;
identify a multi-modality condition along the road segment upstream of the junction based upon an analysis of the multimedia data including the one or more images;
evaluate a plurality of probe points representative of travel along the road segment upstream of the junction in accordance with a detection algorithm to separately determine whether the multi-modality condition exists along the road segment upstream of the junction; and
determine whether to modify one or more tuning parameters of the detection algorithm based upon the multi-modality condition identified based upon the analysis of the multimedia data including the one or more images,wherein the communication interface is also configured to cause an alert message to be provided based upon the multi-modality condition identified based upon the analysis of the multimedia data including the one or more images.

Abstract
A method, apparatus and computer program product are provided to improve the identification and characterization of split lane traffic and other multi-modality traffic conditions. In the context of a method, multimedia data from a camera is received that is representative of traffic conditions along a road segment upstream of a junction. The method identifies a multi-modality condition along the road segment upstream of the junction based upon an analysis of the multimedia data. The method also includes evaluating a plurality of probe points representative of travel along the road segment upstream of the junction in accordance with a detection algorithm to separately determine whether the multi-modality condition exists along the road segment upstream of the junction. The method further includes determining whether to modify one or more tuning parameters of the detection algorithm based upon the multi-modality condition identified based upon the analysis of the multimedia data.
