Abstract:
1. A method for determining traffic velocities along a plurality of traffic routes by using operational data associated with mobile stations operating in a wireless telephony communications network overlapping the traffic routes and comprising a cell sector coverage area having a plurality of cell sectors, comprising the steps of: generating a plurality of traffic data records based on the operational data from the wireless telephony communication network, each traffic data record identifying a location within the wireless telephony communication network for one of the mobile stations at a particular time; generating a movement record in response to processing at least two of the traffic data records associated with a wireless communication activity by a same one of the mobile stations, each movement record comprising locations within the wireless telephony communication network for the same mobile station at different times and reflecting movement by the same mobile station; creating a plurality of traffic routes between any two of the cell sectors by processing cell sector coverage area information for the wireless telephony communications network and geographic information for roadways within the cell sector coverage area of the wireless telephony communications network; identifying from the plurality of traffic routes a particular one of the traffic routes traveled by a vehicle associated with one of the mobile stations by processing the movement records for the mobile station, comprising the steps of: calculating an estimate of a velocity of vehicular traffic along the particular traffic route by using the movement records associated with the particular traffic route.
