1. A method for determining a density of wireless communication devices (WCDs) on a road, wherein the road intersects a plurality of wireless coverage areas, and wherein the plurality of wireless coverage areas serve a first set of WCDs, the method comprising:

  • querying registration data related to each WCD in the first set to determine, as a second set of WCDs, WCDs of the first set that have registered with any of the plurality of wireless coverage areas within a threshold time period;

    determining a respective geographic location for each WCD in the second set;

    comparing the determined geographic location of each WCD in the second set to a predefined geographic definition of the road;

    establishing a third set of WCDs by selecting from the second set each WCD whose determined geographic location is within the predefined geographic definition of the road;

    evaluating the geographic locations of the WCDs in the third set to determine the density of WCDs within the predefined geographic definition of the road, wherein evaluating the geographic locations of the WCDs in the third set to determine the density of WCDs within the predefined geographic definition of the road comprises dividing a number of WCDs in the third set by a predetermined average number of WCDs per vehicle; and

    providing an output based on the determined density of WCDs on the road.
