The memory stores map information including roughness information indicating a roughness of a surface of a road, and the microprocessor is configured to perform: acquiring as driving information of a plurality of vehicles driving on the road, position information of the plurality of vehicles, acceleration information indicating accelerations of the plurality of vehicles, driving image information including a captured image of the surface of the road, and driving sound information indicating driving sound of the plurality of vehicles; evaluating the roughness of the surface of the road based on the driving information of the plurality of vehicles; and updating the roughness information corresponding to the road stored in the memory based on an evaluation result in the evaluating.

A visual reference system can be used with a loading machine such as a bucket loader having a bucket that can be vertically articulated with respect to a work surface. The visual reference system can include one or more illumination devices configured to project a visual fiducial beam toward the work surface. The visual fiducial beam can create a fiducial indication of where the bucket will contact the work surface when lowered adjacent the work surface. The visual reference system can assist in operation of the loading machine by enabling an operator to visually perceive the expected contact point between the bucket and work surface.

Aspects of the present disclosure include systems, methods, and devices to facilitate routing of an autonomous vehicle (AV) based on pick-up or drop-off zones (PDZs) that are usable by the AV at destination location. A request for one or more PDZs that are usable by a vehicle to perform a pick-up or drop-off operation at a specified location is received from a vehicular autonomy system of the vehicle. A set of PDZs that are usable by the vehicle at the specified location is identified based on an association between information associated with vehicle and one or more PDZ objects in a data store. Each PDZ object comprising data describing a PDZ. A response is generated based on the set of PDZs and transmitted to the vehicular autonomy system. The response includes at least one PDZ identifier to the set of PDZs.
