  • System and method for calculating a turn cost for route selection purposes
    Patent number: 12459534
    Abstract: A method for selecting a route along an intersection includes receiving map data, receiving vehicle telemetry data crowdsourced from a plurality of remote vehicles. The method includes determining a sight distance using the map data, determining an average vehicle speed along the intersection using the vehicle telemetry data, determining a time available to navigate through the intersection using the sight distance and the average vehicle speed along the intersection, determining a ratio between the time available to navigate through the intersection and a time required to navigate the intersection, and determining a cost value of the intersection using the ratio between the time available to navigate through the intersection and the time required to navigate the intersection.
