OSM Tag : parking_space_IO

<tag k='parking_space_IO' v='drive_through | back_in | back_out' />

parking_space_IO is an extension to the amenity=parking_space. The IO stands for In Out, describing how a vehicle should ingress and egress the parking space. This tag should be useful outside the autonomy context for vans and large RVs so they can know ahead of time if they will have access to pull-through parking. This would also be useful for parking lots with the stalls designed at an angle.

When dispatching an autonomous vehicle to execute a task somewhere, one must provide a final destination that we'll call a SPOT. There are static and dynamic spots, the static spots are designed into the digital map as <tag k='amenity' v='parking_space' />, parking_space is a standard OSM tag modelling a parking space in a parking lot and not specific to autonomy.

Semantic:

drive_through: (a.k.a. pull through) Vehicles are not expected to have to reverse when using a drive_through spot. They will drive forward to BOTH enter (ingress) and exit (egress) the spot area. So they will enter on one side and exit on the other side of the parking_space.

back_in: Vehicles are expected to reverse to enter (ingress) the parking_space and drive forward to exit (egress) it.

back_out: Vehicles are expected to enter (ingress) the parking_space driving forward and reverse out to exit (egress) it.

NOTE: Reversing NOTE that If a spot is back_in or back out, then it is expected that the lane terminating a the spot will be driven both in forward and in reverse to ingress (back_in) or egress (back_out) the spot. The lane always represents the direction forward of the vehicle.
