Website creating visualization of traffic in Flanders.

Traffic visualization

Website that displays traffic data of Flanders almost in real time.

Project info

The government of Belgium has real-time data about the traffic in Flanders. In this project, I built a website that visualizes the speed of the cars.

The data is available from these URL's:

• raw data: http://miv.opendata.belfla.be/miv/verkeersdata
• some explanation: http://miv.opendata.belfla.be/miv-verkeersdata.xsd
• more explanation: http://miv.opendata.belfla.be/miv-config.xsd
• location data: http://miv.opendata.belfla.be/miv/configuratie/xml

Development setup

The project consists of a nodejs API, some static front end files and a scraping script.

The setup is a bit tedious.

Install scraper

cd backend/scraper
virtualenv venv
source venv/bin/activate
pip install -r requirements.py

Now you can run python data_updater.py to scrape the website. The generated json file will be saved in the folder old_data with its timestamp as a name and will overwrite the file most_recent_data.json.

Frontend

First change the url to the API's url using the variable api_url. Now we need to build everything. Then we need to copy the files to the public folder of our backend.

cd frontend
npm install
webpack -p
mkdir ../backend/public
cp dist/* ../backend/public

Backend

First change the config.js file. After that it is relatively simple.

cd backend
npm install
npm start
