Abstract
Methods and systems for determining the density and velocity of wireless communication devices (WCDs) on a road are provided. A preferred embodiment involves determining a set of WCDs that are being served by a plurality of wireless coverage areas that intersect the road. This set of WCDs is narrowed to include only those WCDs that are (1) presumed to be in motion and (2) within a predefined geographic definition of the road. The density and aggregate velocity of the resulting WCDs is determined. From these determinations, the traffic density and aggregate traffic velocity of vehicles on the road can be estimated and an associated output can be provided.
