An object is to provide technology capable of appropriately recognizing a travel path. A travel path recognition apparatus includes a travel path recognizer. The travel path recognizer calculates a traveling distance traveled by a vehicle from acquisition time of lane marking information to current time based on a vehicle speed of vehicle behavior. Then, the travel path recognizer determines whether or not the lane marking information is information within a usable period in which the lane marking information is usable to recognize the travel path based on a predetermined lane marking acquirable distance and the traveling distance. The predetermined lane marking acquirable distance is a distance in front of a position of the vehicle, and is a distance in which a lane marking of the lane marking information is acquirable.

An example robot performs a scan to obtain image data of a given region. The robot performs image analysis on the image data to detect a set of undesirable objects, and generates a reference map that excludes the set of undesirable objects, where the reference map is associated with the location of the robot at the time of the scan.

A heavy goods vehicle includes a displacement calculator that calculates a displacement by multiplying an arc length per unit rotation angle of the outer circumference of a specified tire by the first physical quantity, a vehicle position estimator that estimates a vehicle position using the displacement, and a memory that stores a correlation between a second physical quantity corresponding to a loading weight and an arc length per predetermined rotation angle at the outer circumference of the specified tire. The displacement calculator refers to the correlation to calculate a current arc length per unit rotation angle at the outer circumference of the specified tire from the second physical quantity corresponding to the loading weight, and calculates the displacement by multiplying the first physical quantity detected by the rotation amount detector by the current arc length per unit rotation angle.

Transmitting route data captured by a traveling vehicle to a remote database includes capturing route data records having route data and a location and time of capture. The captured route data records are stored in a memory of the vehicle and are sent to the database. A route data message is sent at a time randomly selected within a first time interval after the capture of the route data and/or when the vehicle has left a predetermined radius around the location of capture of the route data. The messages can be sent directly to the database, or via a minimum number of intermediate receivers posing as the origin of the data to the respective receiver of a transmission from them.

Techniques are disclosed for determining a location of an object based at least in part on a motion of the object. The techniques include generating a motion profile based at least in part on motion data received from a mobile device that is associated with the object. The techniques further include receiving, from a camera at a location, a plurality of images that identifies a candidate motion of a candidate object through at least a portion of the location. The techniques further include generating a candidate motion profile corresponding to the candidate motion of the candidate object based at least in part on the plurality of images. Based at least in part on a score generated by comparing the motion profile with the candidate motion profile, the techniques may determine that the candidate object is the object.
