发明名称 Variable speed sign value prediction and confidence modeling
摘要 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.

主权项 1. A method comprising: receiving a set of traffic data from at least one vehicle for a defined time period, the received traffic data comprising captured images, videos, or interpreted speed limit values of a variable speed sign; determining, using a processor, a predicted speed limit value for the variable speed sign from at least a portion of the received traffic data; and calculating a confidence level for the predicted speed limit value for the variable speed sign.
