transportation provides a replacement for node's console by using tconsole, so you can inspect the objects in the node.js REPL by using require('transportation/console'):
> var konsole = require('transportation/console')
> konsole(transit)

Command Line
npm install -g transportationtransportation provides a binary transportation. It supports the following commands.
Export Vehicles' Positions as GeoJSON
Prints all vehicles' positions of a specific date as GeoJSON linestrings with time components:
transportation positions /path/to/gtfs/dirBy default multiple trips are simply newline-separated GeoJSON to support streaming. If you want to return a single JSON array use the --array flag. Additional options are available via transportation positions --help. The generated GeoJSON LineString has its time property set as an array of timestamps and is therefore compatible with tools like LeafletPlayback and others.
