One of my favorite moves is when the Dutch simply don’t provide any guidance whatsoever in certain intersections. No signs. Brick or stone paving.

It really works! "When you don't exactly know who has right of way, you tend to seek eye contact with other road users. You automatically reduce your speed, you have contact with other people and you take greater care."

I once saw a mind blowing series of slides from a Dutch transport engineer at a conference, showing the succession of steps taken over the years on a single country lane to reduce the chance of collisions to essentially zero.

It started as a one-lane-each-way road like we all know.

Later ome space was shaved off the sides for bike lanes.

Later the lanes were repainted (without being moved) to appear much narrower. Drivers are more careful when they find it difficult to successfully stay within the paint.

Later (mind blowing part), the one-lane-each-way was repainted as a single narrow lane shared by both directions. So the only supported line of travel guaranteed a head-on collision. This causes drivers to drive very carefully...
