bandicoot

Live map of public transport in Oslo.

This is early work in progress based on a Hackathon in November 2019.

npm install
npm run bootstrap
npm run watch

# Define a directory to store data. E.g:
mkdir /tmp/bandicoot-data
export STORAGE_DIR=/tmp/bandicoot-data

# Run data fetcher.
cd packages/bandicoot-fetcher
STORAGE_DIR=/tmp/bandicoot-data npm start

# Run backend-for-frontend.
cd packages/bandicoot-bff
npm start

# Run webapp.
cd packages/bandicoot-webapp
npm start

# Check the website!
# http://localhost:3000/

The map currently only shows the last reported positions for individual vehicles, and markers move around on the map when we get updated positions.

To do / ideas

• Replace markers in map with better symbols
• Try out Amazon EventBridge for internal events distribution
• Draw route lines
• Filtering and search
• Switch to publish/subscribe for data origin
• Predict movement when missing data
• See historical data for some hours back in time

Port and endpoints allocation

• http://localhost:3000 - webapp
• http://localhost:5000 - backend for frontend
  • http://localhost:5000/events - public events stream
• http://localhost:5001 - fetcher service
  • http://localhost:5001/events - internal events stream

The internal events stream implementation can be replaced with e.g. Amazon EventBridge later.

Data source

Currently using Entur Real-Time API for collecting data using the HTTP GET method (SIRI 2.0 Lite). We want to switch to the publish/subscribe mechanism, but we had not had time to find out how to do to the integration and the docs are not explaining how to do this easily.

The "Real-Time"-iness of this data source is not good enough to produce a real-time map.
