I was following this guidance in the OpebStreetMap Wiki:

List of possible values
The tag takes the form access=*, where * can be any of the following:

Value	Description
yes	The public has an official, legally-enshrined right of access; i.e., it's a right of way.
no	General public access is prohibited. Stronger interdiction than private. Examples: a fully closed road; a restricted military facility.
It is necessary to add additional access (like foot=yes or bicycle=permissive, etc.) to indicate who may use the element, if anyone is allowed. If only specific transport modes are forbidden, for example, at a vehicle no-entry sign, use a more specific restriction like vehicle=no or motor_vehicle=no over the general key access. Keep in mind that sidewalks/pavements are typically included in the highway of the street.
