  • Geographic position calculation for sign placement based on destination profiling of probe data
    Patent number: 11170138
    Abstract: Apparatus and methods are described for identification of a geographic location for sign placement. Probe data is received for a geographic area, and the probe data is collected by one or more sensors. Trips including destinations within the geographic area are matched with road segments from a geographic database. At least one potential sign placement road segment is compared to road segments of the trip. One or more destinations are selected from the trips based on the comparison of the at least one sign placement road segment to the trip road segments.
