Claim 0:
1. An apparatus comprising at least processing circuitry and at least one non-transitory memory including computer program code instructions, the computer program code instructions configured to, when executed by the processing circuitry, cause the apparatus to:
receive subject probe data comprising at least location information of a plurality of vehicles in real-time;
partition the subject probe data associated with a segment into a number of clusters with respect to a lateral dimension of the subject probe data using a clustering algorithm;
identify two width-defining clusters within the subject probe data, wherein the two width-defining clusters comprise a first cluster associated with a maximum average lateral position and a second cluster associated with a minimum average lateral position;
determine a width narrowing measure for the segment based at least in part on comparing statistical measures for the two width-defining clusters within the subject probe data to statistical measures for corresponding clusters within historical probe data associated with the segment; and
provide an indication of whether a width of the segment has been narrowed according to the width narrowing measure to be rendered as an alert at a graphical interface of a device of a driver.
