Last summer we added sun screens to the ground floor of our house. They are on the front and the side of the house, facing the south and the west. It did not take long to realize all four screens have their own closing and opening time. Since we like light in our house, the screens should only close when the sun is shining on the window. But only in summer. But only in good weather. So although the screens are equipped with a remote control and a control box (Somfy Tahoma) with app, the need to automate rose quick!

Yes, we all know the saying “All roads go to Rome”. In this article I will show that a lot has changed in the last 2000 years. It might still be true that all roads go to Rome, but in the Netherlands the public transport does not. It all goes to Utrecht, Utrecht Central Station. There are several visualizations of all roads leading to Rome but for the first time I will show you that public transport goes to Utrecht.

This will be based on the GTFS data of the Netherlands, the trip planner OpenTripPlanner and some magic with GeoPandas

Using open source products and open data to create a stunning visualization of public transport travel times in the Netherlands

One of the greatest developments in Dutch public transport, is the ongoing growth of publicly available data. Combined with OpenStreetMap this results in sufficient information for multi modal travelplanners. The OpenTripPlanner is an example of a very complete tripplanner implementation. This article will show you how to use the OTP and QGis to visualize travel times to all regions in the Netherlands from one start point.

Times are changing, working from home is becoming the new standard and most likely here to stay. 2 or 3 days to the office will become the standard, reducing the days traveling from home…

Open data provided by Dutch public transport makes it possible to visualize crowdedness over the day.

One of the greatest developments in Dutch public transport is the ongoing growth of publicly available data. Time schedules have been available for several years, including real-time updates and crowdedness information was added a couple of months ago. All this open data makes it possible for developers to create apps, both for the great public and for niche markets. In this article I will show you how to create a great view of the crowdedness of trains in the Netherlands.

The data sources used for this product are OVInfo for time schedule information and NDOV, for the crowdedness information. The…
