A traffic-flow prediction for a roadway segment is obtained at the processing hub by receiving an externally generated prediction, or generating the prediction locally. The prediction is obtained. Traffic-flow prediction data, which is individually collected by multiple traffic probes and associated with the roadway segment, is obtained, and saved as recorded traffic data. A validation module generates a verified traffic-flow prediction based on a subset of the recorded traffic data, wherein the subset of the recorded traffic data. Traffic-flow prediction data collected by a first subset of traffic probes is included, but traffic-flow prediction data collected by a second subset of the traffic probes is specifically excluded. A quality index is generated based on a degree to which the traffic-flow prediction corresponds to the verified traffic-flow prediction. The traffic-flow prediction is conditionally corrected based on the quality index. Traffic messages including the prediction are sent to at least one user device.
