Coenderstraat, Delft.
A simple looking junction, but the more you look, the more you see the Dutch Sustainable Safety design approach in action.
Everyone moves in their clear space on the main road, interactions are managed, and people have priority in the side street, Westerstraat.

Actually, on closer reading (yes, @rantyhighwayman.bsky.social's work feed!) the layout is probably more like this.
Strip width is not modified, so 2.4m to 10m as now.
It is the give way lines for the crossing (dia.1001.5) which have been modified in their distance from the stripes.

The definition of sustainable transport modes should not continue to include “ultra low emission vehicles”. Sustainability cannot be reduced to tailpipe emissions, as even electric cars have huge environmental and social consequences.

Riverside, Cambridge. Not on a boundary, but similarly a short section of cycleway between two sections of street open to traffic. NB also protecting junction between two active routes (bridge descending to the right).

This modal filter on Cromvlietkade marks the border between Rijswijk and Den Haag. It's not a route for motors, but provides a main cycling route which subtlety changes from cycle street to cycle track and back to cycle street with no loss of momentum for people cycling.

Cycling in the Netherlands isn’t a novelty — it’s everyday transport.
I made a new post and video explaining key traffic signs and priority rules — for anyone planning to ride here.

Key traffic signs and priority rules — for anyone planning to ride in the Netherlands
You’re very welcome to ride a bicycle in the Netherlands, whether during your holidays or as part of a study tour. But for everyone’s benefit — and especially for your own safety and that of others — it really helps to know the basic rules of the road. Locals sometimes complain about the behaviour of visitors on rental bikes, and it would be great if your presence in traffic didn’t draw negative attention.

We've had them for real in Brighton since *May* 2013 when 14 floating bus stops were installed along Lewes Rd. Opened by then Roads Minister Norman Baker without much fuss (also @iandaveysussex.bsky.social)... Been working fine for over a decade & AFAIK no reported conflicts with bus passengers

A floating bus stop being trialled by TRL for Transport for London in November 2013. It reminds us that the unfamiliar takes time to become familiar and it isn't always a simple journey. Perhaps the conversation needs to shift to a real vision of human-scale future streets?

Actually lots of extra help in this guidance with more nuance around different conditions and much of this should be standard practice anyway.
It won't change the minds of the folks who are against floating bus stops and it still leaves us with the edge cases of shared use bus boarders plus

Seen somewhere in Chichester City Centre, this is a local piece of guerrilla humour by the Chichester Anti-Recreation Society (CARP) which is a poke at the city city being apparently too serious about little things.

As Dutch cities continue to grow, space is being reallocated to walking, cycling and public transport. Across the Netherlands, the role of the private car is being reconsidered. New blog post and video.
When Space Runs Out: Rethinking the Role of the Car in Dutch Cities
Dutch cities are changing rapidly. One of the aims of this blog is to document that change, and there is plenty of work ahead. Much of what I record involves changes to streets: a before-and-after of a reconstructed street is relatively easy to capture in images. Shiny new cycling bridges can steal the show, and a new continuous-cycle route perhaps even more so.

I do like this little scheme on Bayley St - just off Tottenham Court Rd.
This was a signal controlled junction from a one-way street, contraflow cycling was added & then the junction filtered with a cycle track.
Now it's a bike lane & a new public space with SuDS. 🚲☔️☘️💚

Many streets in the Netherlands once looked like those in the UK today. What matters is what happened next. Hoogeveen shows this clearly: a car-dominated main road in 2019, upgraded by 2024 with cycle tracks. Dutch roads are continuously improved to make cycling safer & neighbourhoods more pleasant
