Hi Michał,
Certainly it doesn't make sense to talk about bus stops when the road
network isn't even finished yet. Totally agree.
The point is, we are in the process of establishing a kind-of-standard
about public transport network. There has been lots of struggle about
this topic, and therefore it's quite an important process.
Since I am working on a project that deals with navigation for the
blind and visually impaired, I know how important these mapping
standards (if you can call anything in OSM a "standard" at all) are.
If we continue to stick to the old scheme, or any extremely simplistic
scheme, we are simply missing the basis for future development in the
area of blind people's navigation (and probably many other areas as
well).
Yes, we are - at the cost of (sorry to repeat the mantra) "efficiency,
compatibility with the existing software and easier learning curve".
From our point of view (or mine, depends how you see it), the quality
of the final product is a mathematical product of quite a few parameters
(including the mantra above), NOT the quality of the data alone.
I'm not saying everybody should do it now and everywhere. But the
proposed public transport scheme is a solid basis to work with and one
that is scalable enough to meet requirements we might not yet be
thinking about.
I've already provided my criticism to the proposed schema, so not to
repeat myself, on another topic:
I have been sort of thinking along the same lines as you are here
(assistance to the users of public transport). I came to the conclusion
that the easiest thing would be to take the bus stop code and combine it
with the link to the local timetable online. For example, to cover
entire area of Germany one would need to import stop codes as the
"stop_id" tag, and then have a list of online timetables combined with
geographical location those timetables cover. As some people (myself
included) have already imported stop_id's, the last step - the mapping
of public transport authorities to the geographical area, and providing
a link to the online timetable is relatively banal. An overlay would
then take the stop_id, combine it with the URL, and here opens your
timetable website.
I am writing this, because I have heard of NAPTAN, and I am sure a
similar plan could be applied in the UK. My point is not to reinvent the
wheel, no matter how much one likes programming.
cheers
