A method of validating traffic-flow predictions includes obtaining traffic-flow prediction, associated with a particular roadway segment and a particular time. Recorded traffic data corresponding to the particular roadway segment and the particular time, which includes data from traffic probe devices, is obtained. A subset of the recorded traffic data, limited to data obtained from a subset of the traffic probe devices, is obtained, and used to generate an estimated actual traffic-flow. At least a first quality index, which is based on a degree to which the traffic-flow prediction corresponds to the estimated actual traffic-flow, is generated. If the at least a first quality index satisfies at least a first quality threshold, the traffic-flow prediction is flagged for review.
