In my opinion time tables are not geographical data. That's why I would
not stick them in a database of a project that aims to collects geo
data. 

Also (and more importantly), the data model of OSM is INHO completely
unsuitable to handle time tables. It would, of course, be possible to
devise some clever way of encoding bus stops in tags, but that would be
very difficult to edit and even more difficult to query. Therefore, I
think it is a better idea to create a different database for this type
of information and simply link it to the bus stops in OSM.

Yes, that would be really cool, but it does not mean that all the data
has to come from the same database.

There could be a feature request for this, right? Is there a problem and 
reason why not to include time tables in OSM?

I would love to see OSM transit map with time tables so that I could 
check when some bus/tram should arrive at my stop.

Cheers.

Is it possible to make it using only opnestreetmap data, so that it open 
and legal?

Technically it is easily possible: All stops imported during the NaPTAN
import have a tag called naptan:NaptanCode. This tag can be used to
request real-time information (e.g. via text messages). In the West
Midlands area this information can also be accessed via
http://netwm.mobi/. So, theoretically you could simple display an
overlay with bus stops in OpenLayers (like Novam [1] does) and
automatically query netwm.mobi when the user clicks on a stop and
display the netwm's output in a popup.

However, I reckon there are legal problems with this approach :-)

Cheers,
Christoph

The problem is that you need real-time data from the bus route
operators to know where their busses are. Since this data is constantly
changing Openstreetmap is -- in my opinion -- not the right place for
it. It would also be handy to have the timetables in a database as
well; I am not aware that anyone is adding timetables at the moment
and again I would not use OSM for that.

Nonetheless it would be really cool to produce such a map.

Cheers,
Christoph

[Talk-transit] Real-Time Bus Map

2009-11-03 Thread Valent Turkovic
http://googlemapsmania.blogspot.com/2009/10/real-time-bus-map.html

Is this possible with OpenStreetMap? I would like to make Real Time Bus 
Map for my home town. We have created bus and tram relation tracks and 
this would be the next step, if possible.

Cheers.
