Patent Images
1. A method comprising:
- receiving a set of traffic data from at least one vehicle for a time period, the set of traffic data comprising captured images, videos, or interpreted speed limit values of a variable speed sign; and
determining, using a processor, a speed limit value for the variable speed sign from at least a portion of the set of traffic data.

Abstract
Systems, methods, and apparatuses are disclosed for predicting the value of a variable speed sign (VSS) and determining the predicted value'"'"'s associated confidence level. Highly assisted driving (HAD) vehicles may read or capture images of the VSS. The speed limit values, images, or videos of the VSS are reported and received by a network and database for analysis. A predicted speed limit value is determined for the variable speed sign from at least a portion of the received traffic data. A confidence level is also calculated for the predicted speed limit value for the variable speed sign.
