Query for Relations Associated with A Way

Question

Hi OSM community,

I am new here and would be grateful if you could help me with the following.

Background

I am developing an android app that uses OSM maps. (Using Nutiteq SDK)

Question

I would like to know how to query for the bus services (relations) associated with a way id.
Example: With a way id, for example 157561015, realize that bus services 170, 171, 184, ... are associated with this way.

Suggestions

I noticed that openstreetmap.org has the capability to perform such a query. See http://www.openstreetmap.org/way/157561015 . Scroll down the "side-bar" to see relations
Convert OSM map data into a form that can be used to create a database. Is there an easy way of doing this? (for e.g. Spatialite?)

Thank you for reading.

Regards, David

The website obviously has access to the main database. For external apps that are not editors, we prefer (strongly) that you use the overpass-api. You can use Overpass turbo to test your queries. These are all the bus routes using way 157561015.

If later your app becomes wildly successful, we actually prefer you setup your own database. ;)

I think you answered your own question: spatialite osm raw

Thank you cartinus.

A "relation" node in the response has "member role" elements like so:

¶

■

</relation>

¶

Might you also know how to shorten the response by leaving out "member role" elements?

There is now a new feature in Overpass that gives you the relations without the members.

In stead of:

(
  way(157561015);
  <;
);
rel._[route=bus];
out;

write:

(
  way(157561015);
  <;
);
rel._[route=bus];
out tags;

The only change is the last word.
