Key:parking:both:staggered

Staggered parking: Vehicles are parked sometimes on one road side, sometimes on the other because the carriageway is too narrow to park on both sides at the same time (and no "traditional" side for parking is established).
parking:both=lane
parking:both:orientation=parallel
parking:both:staggered=yes

parking:both:staggered=yes is used when mapping street parking to indicate staggered parking.

On some streets, parking is theoretically possible on both sides, but they are too narrow so that in practice parking is only possible on one side without obstructing traffic. In many places, one of the both sides is used for parking regularly in this case (vehicles are "traditionally" parked on one side or because it is structurally more convenient, e.g. on a side where there are no driveways), which can be well represented by parking:side (e.g. parking:left=no + parking:right=lane).

However, it can also happen that the vehicles parked staggered — sometimes on one side, sometimes on the other. The adjacent picture shows, that this also has an influence on the driving line of the flowing traffic.

Use parking:both:staggered=yes to record such situations. All other attributes (parking:side, parking:side:orientation etc.) are tagged as if the vehicles park on both sides.
