Hi all,<br><br>I have a question regarding access=private vs access=destination. In the Portland area, we have some apartment complex roadways that have been tagged as access=private. Paul makes the point that routers should be able to route on access=private as a last resort. However, in my opinion, there is a problem with adding access=private - most routers will
not permit anyone to use those streets. In
OpenTripPlanner's case (<a href="http://opentripplanner.com/">http://opentripplanner.com/</a>), if it is given a starting destination within an
apartment complex tagged with access=private, the router will try to
snap that location to the nearest permitted road, which in some cases,
may be an irrelevant or disconnected road to the origin. Paul suggests this might be a flaw in the code and maybe he is right.<br><br>Do you think it
makes more sense to tag the apartment complexes as access=destination or access=private?
The complexes are not usually private. I can drive into them without a
key card (usually); I shouldn't be using them as a through street, but
they are permitted for use if my destination is on that complex street.
For OpenTripPlanner, access=destination is permitted. Should we permit routing on access=private or change the tags?<br><br>OpenTripPlanner tries to base its implementation off of OSM documentation, but I could see how apartment complex parking lots is a cross between a private driveway and a customer parking lot.<br>

The access=private tag is generally used in combination with the road
network tags, with the purpose of indicating that the road is not to be
used by the general public.
<p>Usually used for Private driveways (in the city) and country lane ways, where the road just leads to a private home.
<b>Routing programs would be able to detect this tag, and knows to avoid these roads when routing.
