Correcting speed estimations using aggregated telemetry data

A non-transitory computer-readable storage medium of a computing device storing executable computer instructions, the instructions configured to, when executed by a hardware processor on the mobile computing device, perform steps comprising:

• estimating, for an electronic map comprising road data specifying a plurality of roads in a plurality of geographic regions, a speed associated with a segment of a road of the plurality of roads;
• identifying a speed correction mapping configured to transform estimated speeds to corrected speeds, the speed correction mapping determined from a subset of the road data, wherein the speed correction mapping is provided by a machine learned speed correction model trained to take estimated speeds as input and output corrected speeds;
• transforming the estimated speed to a corrected speed based on the speed correction mapping;
• and
• sending for display the corrected speed as part of an electronic map application.
