Abstract
Customized routing of vehicles is performed based on lane-level difficulty includes extracting data elements from traffic information indicative of performance of maneuvers by the vehicles. Raw difficulty scores are determined for each of the maneuvers based on the data elements. Lanes of travel are identified for the maneuvers. For each lane, a lane-level difficulty score is generated based on the raw difficulty scores corresponding to the maneuvers using that lane. Vehicles are routed accounting for the lane-level difficulty scores to include only maneuvers that have lane-level difficulty scores at or below a difficulty preference.
Claims20
A system for customized routing of vehicles based on lane-level difficulty, comprising:
- a data store configured to maintain lane-level difficulty scores for a plurality of lanes of travel of roadway, the lane-level difficulty scores being computed based on traffic information compiled from a plurality of vehicles having traversed the roadway;
- and
- one or more processors, configured to:
- receive a query for a route from a vehicle,
- identify a difficulty preference for the vehicle based on the query,
- compute the route to include only maneuvers that have lane-level difficulty scores at or below the difficulty preference, and
- send the route to the vehicle, responsive to the query.
A method for customized routing of vehicles based on lane-level difficulty, comprising:
- extracting data elements from traffic information indicative of performance of maneuvers by the vehicles;
- determining raw difficulty scores for each of the maneuvers based on the data elements;
- identifying lanes of travel for the maneuvers;
- for each lane, generating a lane-level difficulty score based on the raw difficulty scores corresponding to the maneuvers using that lane;
- and
- routing vehicles accounting for the lane-level difficulty scores to include only maneuvers that have lane-level difficulty scores at or below a difficulty preference.
A non-transitory computer-readable medium comprising instructions for customized routing of vehicles based on lane-level difficulty that, when executed by one or more processors, cause the one or more processors to perform operations including to:
- extract data elements from traffic information indicative of performance of maneuvers by the vehicles;
- determine raw difficulty scores for each of the maneuvers based on the data elements;
- identify lanes of travel for the maneuvers;
- for each lane, generate a lane-level difficulty score based on the raw difficulty scores corresponding to the maneuvers using that lane;
- receive a query for a route from a vehicle;
- identify a difficulty preference for the vehicle based on the query;
- compute the route to include only maneuvers that have lane-level difficulty scores at or below the difficulty preference;
- and
- send the route to the vehicle, responsive to the query.
