Abstract: To improve mapping data collection, a route management system and a user application to assist drivers of a fleet of mapping vehicles are implemented. A route management system can improve route creation, assignment, monitoring, and validation. The user application can provide turn-by-turn instructions to a driver to complete a mapping route, thereby obviating the need for a navigator. The user application can also solicit user feedback from the driver if a road segment was missed. User feedback can be used to update coverage information. The coverage information may be used by the route management system to modify assigned mapping routes or assign new mapping routes to the fleet of mapping vehicles.

Abstract: Systems and methods for vehicles to detect roadside shelters that can protect users from exposure to various weather conditions. Roadside shelter information can be mapped and added to a mapping database. Systems and methods are provided for live autonomous vehicle perception of viable shelters via machine learning. Shelter information can be incorporated into autonomous vehicle logic and decision-making for user pick-up, drop-off, delivery access, and any other user vehicle access. A user may prefer to wait for a vehicle underneath an awning or inside a bus stop shelter to avoid exposure to inclement weather. Vehicle sensors can be used for perception of roadside features.

Abstract: Micro-authorization of remote assistance for an autonomous vehicle is described herein. A constraint that inhibits propulsion by a mechanical system of the autonomous vehicle is activated by a computing system of the autonomous vehicle, wherein a signal that identifies the activated constraint is transmitted from the autonomous vehicle to a remote computing system.

A return signal is transmitted from the remote computing system that specifies instructions to deactivate the constraint and a distance to desirably advance the autonomous vehicle. The computing system of the autonomous vehicle deactivates the constraint and the mechanical system is controlled to advance the autonomous vehicle when signal latency is less than a predetermined threshold duration of time.
