[Tagging] Handicap Parking Access Aisles

[Tony Shield]

Having today downloaded and read SN01360 [2] |I disagree with the 
interpretation. In that document there is only one mention of 'aisle' it 
being an 'access aisle' in Section 5.4 paragraph marked Off-Street 
Parking  -" *Off-street parking*: bays should be a minimum of 4800 mm long
by 2400 mm wide with additional space: (1) where bays are
parallel to the access aisle and access is available from the side an
extra length of at least 180 0mm, or (2) where bays are
perpendicular to the access aisle, an additional width of at least
1200 mm along each side.

I read that as saying the 'access aisle' is that which in OSM is marked 
as 'parking _aisle', and it leads to a parking bay designated for 
disabled users, the 'access aisle' is not exclusively for the use of 
disabled users. I am of the opinion that 'access' is misinterpreted to 
refer only to disabled users which is a very restrictive interpretation 
of the usual interpretation of access being for anybody. I think it is 
something to be very careful about.
Usage in the UK supports my interpretation - I know of many car parks 
where ordinary and disabled spaces are next to each other and accessed 
by a single way which has no restrictions.

For parking bays I think that the tag:amenity=parking _space is clear.
