Here’s a video from BicycleDutch.
For the cyclist, this is a variant on the two-stage turn queuing box (2STQB), or what I once called the “cross-street bike box” — but with a couple of significant differences.
A 2STQB as in the USA on the far right corner is used only for left turns. In the Dutch design, the cyclist who is traveling straight ahead heads into a 2STQB before the cross street, and if turning left, then another one to make the left turn.
Dutch drivers are required to yield right of way to cyclists both when entering and when leaving the intersection, just as they would to pedestrians. Dutch drivers understand this and do this — however, if bicycle traffic is heavy, with serious effects on efficiency and capacity for motor travel.
The video says nothing about signalization, if any, and it completely avoids the issue of delay.
If you step back and look, this reveals itself as a conventional four-way intersection inside a roundabout. Cyclists travel in the roundabout, and motorists must cross it when entering and leaving.
“This is a standard US road from the latest urban design guide with the official lane widths.”
Wrong. The reference is to the NACTO guide, which does not have official status. The NACTO guide was created by advocates for greater bicycle mode share, and includes numerous treatments which have no official status and which create conflicts. The treatment shown would be regarded as an experimental treatment by the US Federal Highway Administration. The double weave, with one lane crossing another, is not an approved treatment in the official reference, the Manual on Uniform Traffic control Devices. Furthermore, this treatment has been used in the USA only since approximately 2008. As of 2025, NACTO also has disowned this treatment.
The narration in the video says that motorist left turns can often be made as quickly as they could be made in the street, but an uninterrupted left turn can only be made on a stale green, so the green for the cross street starts just as the cyclist arrives on the far right corner.
I have another post commenting on an American consultant’s promotion of this type of intersection, linking to more information from BicycleDutch, and raising additional issues.
