The lanes:psv=* key can be used to mark the number lanes reserved for public service vehicles on a way.

The most common value is 1, when a psv lane exists. For a two-way road with dedicated psv lanes in both directions, the value would be 2. If the lane is exclusive for buses only (no taxis allowed, for example), use lanes:bus=* instead.

Where a way element has a psv lane only in one direction, use lanes:psv:forward=*, and lanes:psv:backward=* when that lane is usable in the direction of the way, or against the direction of the way, respectively.

If the whole road is exclusively for psv's, use regular access conditions: access=no + psv=yes ; motor_vehicle=no + psv=yes when shared by bicycles ; or else highway=bus_guideway where applicable.
