As far as I can tell, some progress was made previously on importing
NaPTAN data for specific areas of the UK. However, the process for
requesting an import on the wiki seems to have broken down somewhere
along the line and I believe the python script mentioned on the wiki is
outdated.
In may experience, a lot of the original NaPTAN imports have decayed:
- people have double mapped stops and the the NaPTAN one has been deleted;
- stop have moved and got double mapped and deleted as a result;
- stops have been temporarily out of service, e.g whilst redeveloping a
bus station, and been deleted and then lost the NaPTAN associations when
remapped.
Also, all bus stops need continual maintenance because names get changed
as landmarks come and go.
Given that few people like maintenance work, if you can't map all the
stops from first principles, it is very unlikely that imported ones will
get maintained. Retaining the NaPTAN tagging is important in allowing
any later remerge of the updated NaPTAN data.
Another problem with NaPTAN stops, which applies to non-OSM users as
well is that they have virtual stops in Hail and Ride areas. Routers
seem to only like people boarding at those place, so, in my case, can
take me about 7 minutes out of my way against the direction of travel,
so tell me I have missed a bus that could be easily caught.
