Transport Spider

This is a little Ruby script to generate graphics showing the relationships between OpenStreetMap transport / transit related objects.

What you need

You need graphviz installed, as Transport Spider uses that to generate PDFs. Transport spider is written in Ruby, so needs that and the package manager Bundler installed.

After that, run bundle install in the source directory to complete the installation.

How to run it

Type make. If you want to use a different Overpass server, then set that using make OVERPASS_URL=http://localhost/interpreter, or whatever your Overpass server is called. Make sure to include the full URL to the interpreter.

How it works

Each input is a pair of type,id which give the OSM type and ID of a station. For example, Paddington Station, London, UK is OSM way number 302026559, so paddington.input contains way,302026559.

The Transport Spider downloads that, and looks for relations using it which are part of the public transport schema and follows the “web” of connections until it finds transit lines.

More detail on the procedure can be found in the blog post.
