As Easy As Riding A Bike)
The N470 is a main road that runs east from the Dutch city of Delft, connecting it with the city of Zoetermeer. It is 12 kilometres long between the junctions with the A13 motorway (bypassing Delft) and the A12 motorway (which runs between The Hague and Utrecht).
As can be seen from the map above, it is, effectively, a bypass of the town of Pijnacker, bending south around it. Before this road was opened in 2007, a large proportion of the motor traffic running between Delft and Zoetermeer would have passed through the town. Now all that motor traffic is far away from human beings. This applies both at the large large scale – the way the road is built away from urban areas – and also at the scale of the road itself, where, as well shall see in this post, human beings are kept completely separated from it.
This modern road has been built according to the principles of Sustainable Safety, or Duurzaam Veiling – the Dutch approach to road safety. This programme was only developed in the mid 1990s, so it is relatively recent, but it completely underpins the way roads and streets in the Netherlands, both old and new, are designed and built to maximise the safety of human beings. The N470 is an excellent example of these principles in action, and this post will look at them in turn.
Perhaps one of the most important principles of Sustainable Safety, ‘Functionality’ means that every road and street in the Netherlands should have a single function – mono-functionality – and that every region should classify their roads and streets accordingly, either as a
- Through road – for fast traffic, travelling longer distances, in large volumes. Motorways, trunk roads, bypasses, and so on. Roads humans won’t ‘engage with’, by design.
- Access road – the ‘end destination’ for journeys – places where people live, work, shop, relax, and so on.
- Distributor road – the roads that connect up the through roads and access roads.
