Source code for the website bustimes.
It's a magnificent monolithic Django app that's evolved over time (since 2015). The structure doesn't make complete sense:
| app | concern |
|---|---|
| buses | contains the site settings.py |
| busstops | bus stops - but also operating companies, places, and routes 🤯 and all the site CSS and JavaScript |
| bustimes | getting timetable data out of various formats (GTFS, TransXChange, ATCO-CIF) and into a database and doing stuff therewith |
| vehicles | tracking buses' locations and showing them on a map, and pointless details about vehicles' colours and features |
| departures | listing the "next departures" at a bus stop – from a timetable and/or predicted by an API |
| disruptions | information about like roadworks, diversions and stuff |
| vosa | the Great Britain Traffic Commissioners' bus service registration data. VOSA is the name of a defunct UK government agency. |
This documentation is incomplete and out of date. And that's OK (?) because I don't expect anyone to need to follow it. I will try to document some things for my own reference.
I'm using Python 3.8 and I don't know if any lower versions still work. Use Pipenv to install the Python dependencies (Django, etc):
pipenv --python 3.8
pipenv install --dev
There are also some JavaScript dependencies:
npm install
import.sh will download data from various sources and run the necessary Django management commands to import it.
When run repeatedly, it will only download and import the stuff that's changed.
It expects to be run from the data directory.
It needs a username and password for the Traveline National Dataset step.
Some "live" data – departure times at stops, and vehicle locations – is/are fetched as and when a user accesses a page.
For the rest, there are some Django management commands that need to be run indefinitely in the background. These update the big map of bus locations, etc.
