Traveline Data Viewer

This project assists you to display bus timetable data on a map, and is used by https://buildmorebuslanes.com/

This project:

  • dsecribes where to find the data you need
  • has scripts which put that data in a database
  • has code to provide that data in GeoJSON format over an API
  • has code for the buildmorebuslanes.com front-end

What to do

Set up the server

apt-get install \
	git \
	apache2 libapache2-mod-wsgi-py3 dehydrated \
	postgresql \
	python3 python3-psycopg2 python3-flask python3-lxml
adduser --system --shell=/bin/bash --disabled-password travelinedata

Make an apache config, see example_apache.conf

Set up Lets Encrypt: vim /etc/dehydrated/domains.txt and dehydrated -c

Make a new database:

sudo -u postgres createuser "travelinedata"
sudo -u postgres createdb travelinedata -O "travelinedata"
sudo -u postgres psql travelinedata -c 'CREATE SCHEMA travelinedata;'
sudo -u postgres psql travelinedata -c "GRANT ALL ON SCHEMA travelinedata TO travelinedata;"
sudo -u postgres psql travelinedata -c "ALTER USER travelinedata SET search_path TO 'travelinedata';"

Importing data from fresh

Delete all old data and create a new schema

python3 -m tlparser --destroy_create_tables

Add location of bus stops, by adding files to naptandata/ and

python3 -m tlparser --naptan

Add location about postcodes, see postcodes/readme.md.

Add timetable data, by adding files to travelinedata/ and

python3 -m tlparser --process

Transactions are committed after every xml file, so killing --process with Ctrl+C is fine.

Calculate or re-calculate data tabes which are calculated from these values by

python3 -m tlparser --generate --matview

Run the server (which uses flask, so you should probably deploy that properly like a normal flask site):

python3 server.py
