About

This Ruby script is used to convert a set of GTFS files into a SQLite database + GeoJSONs needed by the Transit Map web application that animates vehicles on a map based on timetables and network.

The script was tested on OSX machines with Ruby 1.9.x

Install

  • clone / download the copy of the repo on your machine
  • install required Ruby Gems

(sudo) bundle install

Setup

  • create a folder inside ./gtfs-data and name it with your project information
    • the name of the folder can contain letters, digits, +, - characters only
  • in this folder unzip the GTFS dataset
  • edit the Rakefile and change the PROJECT_NAME constant with the folder name, i.e. sfmta
  • you are ready to parse the GTFS data if you have this folder structure and running rake -T shows the available tasks: http://screencast.com/t/9bt3i3lfL

Parse GTFS data

In a terminal window run the following Rake tasks:

cd /path/to/GTFS-viz

# Initialize folders and the SQLite DB
rake setup:init 

# Fill the DB tables defined in ./inc/gtfs_mapping.yml
rake parse:gtfs_2_sqlite

# Generate GeoJSON files from shapes.txt and stops.txt
# If the shapes.txt is missing from the GTFS dataset, generate one based on stops.txt
rake parse:shapes_2_geojson
rake parse:stops_2_geojson

# Generate KML files from shapes.txt and stops.txt
rake parse:gtfs_2_kml

# Find the position of the stops along the shapes, store them in ./tmp/sfmta/trips_shapes.json
rake parse:stops_interpolate

# Update DB trips and stop_times
rake parse:stops_trips_update

Check the contents of ./tmp/sfmta - http://screencast.com/t/V3r5TZBn0m

  • gtfs.db - SQLite DB tables of calendar.txt, routes.txt, stop_times.txt, stops.txt, trips.txt
  • gtfs_shapes.geojson, gtfs_stops.geojson - GeoJSON files of shapes.txt, stops.txt
  • gtfs_shapes.kml, gtfs_stops.kml - KML (Google Earth) files of shapes.txt, stops.txt

Visualize

You can open the GeoJSON files with QuantumGIS or any other GIS software. Same with the KML files which can be visualized using Google Earth.

If you want to create an animation of the GTFS data you will need to

  • download / clone the Transit Map web application
  • download / clone the Transit Map Route Icon PHP script
  • edit Rakefile and change the PATH_TO_APP_TRANSIT_SIMULATOR, PATH_TO_SCRIPT_ROUTE_ICON constants

In a terminal window run the following Rake tasks:

# Populate FusionTables with shapes.txt and stops.txt
# This task requires configuration of the FT user/pass/key in ./inc/ft_login.rb
rake project:deploy_fusiontables

# Copy the files needed by the Transit Map web application
rake project:deploy

Now, you should be able to see some action in your browser :)
