A method, computer-readable storage device and an apparatus for estimating the traffic speed for segments of roads using location information of wireless devices in a wireless network are disclosed. For example, the method computes a speed and a speed error for travelling between at least two locations of the plurality of locations, correlates the speed and speed error with one or more segments of one or more roads, aggregates the speed and the speed error that are correlated with the respective segment of the respective road, within a pre-determined time interval, computes an average speed, a composite speed error, and a speed variance to a predefined accuracy level for the respective segment of the respective road, in accordance with the plurality of speeds and speed errors that are correlated with the respective segment of the respective road, and provides the average speed as the traffic speed. |

1. A method for estimating a traffic speed in a wireless network, comprising:
receiving, via a processor, a plurality of locations of a plurality of mobile user endpoint devices; computing, via the processor, for each respective mobile user endpoint device, a speed and a speed error for travelling between at least two locations of the plurality of locations that are received for each respective mobile user endpoint device; correlating, via the processor, the speed and speed error that are computed for each respective user endpoint device with one or more segments of one or more roads; aggregating, via the processor, for each respective segment of each respective road, the speed and the speed error that are correlated with the respective segment of the respective road, within a pre-determined time interval; computing, via the processor, for each respective segment of the respective road, an average speed, a composite speed error, and a speed variance to a predefined accuracy level for the respective segment of the respective road, in accordance with the plurality of speeds and speed errors that are correlated with the respective segment of the respective road; and providing, via the processor, the average speed as the traffic speed for each respective segment of the respective road. |
