PyBusMap is a real-time map of public transit vehicle locations for any agency that uses Nextbus vehicle trackers. You can see it live at rutge.rs.

It's written in Python 3 with Flask and SQLAlchemy. It uses Celery and requests-futures to get real-time data from NextBus at regular intervals. That is collected in a PostgreSQL database, and displayed on a Leaflet map.

This project is at v1. It is a feature-complete rewrite of the original PHP version. There are a few features planned, like route planning (directions to a place) and maybe a native mobile app (some day). Feature suggestions are welcome!

• Install system-wide dependencies
  sudo apt-get install python python-pip python-virtualenv libxml2-dev libxsl-dev
• Create and/or activate your virtualenv
  Create: virtualenv venv Activate: . venv/bin/activate
• Install dependencies
  pip install -r requirements.txt
• Initialize database
  python manage.py db upgrade
• Run development server
  python app.py
• (Another terminal, also in virtualenv) Run celery for background task processing
  celery -A celerytasks.celery worker --beat
• Create instance/config.py and override the following config.py parameters:
  AGENCIES = ["agencytag1", "agencytag2"] SECRET_KEY = 'GENERATE_SOMETHING_SECURE_HERE' SQLALCHEMY_URI = 'postgresql://user:password@localhost/db_name' SQLALCHEMY_DATABASE_URI = SQLALCHEMY_URI
  You can generate the secret key with apg -sm32. Get agency tag(s) from NextBus.

You should now be able to access the instance on port 5000.

To run BusMap in production you need an application server. I use uWSGI in emperor mode. On Debian, this means that per-application uWSGI configs belong in /etc/uwsgi/apps-enabled/appname.ini Here's a sample uWSGI config for this application:

[uwsgi]
plugins = python
module = app
callable = app

# Paths
base = /var/www/pybusmap
home = %(base)/venv
chdir = /var/www/pybusmap
pythonpath = %(base)
socket = %(base)/uwsgi.sock

# Who the app runs as
uid = anton
gid = www-data

# Worker behavior
die-on-term = true
vacuum = true
smart-attach-daemon = /tmp/pybusmap-celery.pid %(home)/bin/celery -A celerytasks.celery worker --beat --pidfile=/tmp/pybusmap-celery.pid --logfile=%(base)/log/celery/%n.log
