Method and apparatus for evaluating traffic approaching a junction at a lane level

摘要

A method, apparatus and computer program product are provided to analyze the vehicular speeds along a link that approaches a junction at the lane level. In the context of a method, a plurality of clusters of vehicular speeds are identified from probe data along a first multi-lane link that approaches a junction. For a respective lane of traffic of the first link, the method determines a value associated with the traffic having a respective state of traffic flow from among the different states of traffic flow associated with the clusters of vehicular speeds along the respective lane of traffic of the first link. The method further includes repeatedly determining the value associated with the traffic having a respective state of traffic flow from among the different states of traffic flow associated with the clusters of vehicular speeds for each different lane of traffic of the first link.
