Claim One:
1. A navigation system comprising: a communication interface configured to receive multimedia data 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; 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, 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.
