Planned field guide + interactive (20 pp + Interactive). How do cities design cycling as transportation instead of recreation? This investigation is on the Atlas editorial roadmap; the draft has not yet been published. (Roadmap placeholder.)

An Atlas Interactive

What does it actually take to design a street where cyclists, pedestrians, and cars can share space safely?

Choose a street type. Click any part of it to see why it's built that way.

The selector is discrete on purpose. In the Dutch Sustainable Safety doctrine a street is first assigned a category (through-road, distributor, access road) and its design follows from the assignment. Safety here is a classification, not a dial, so there is nothing continuous to slide between.

3 parts of this street are selectable. Click the drawing to see why each is built the way it is, or choose another street type above.

The Junction, Imported

Street categories are the Dutch export everyone can see. The subtler export is intersection geometry, and its documented American arrival has a date and an address: August 2015, Covell Boulevard and J Street, Davis, California. Proposed by City Councilmember Brett Lee and designed with the Dutch consulting firm Mobycon, it was the first protected intersection built in the United States. Well-established

The documented geometry, drawn in plan; presentation stylized

Corner refuge islands

Four raised islands, one per corner, that block right-turning vehicles from cutting across the cyclist's path. The turning car is held to a wider, slower arc and meets the crossing at close to a right angle, with the cyclist in front of the windscreen rather than beside the mirror. Well-established

Advanced stop lines

The cyclist waits ahead of the stopped traffic, inside the driver's forward view. The sightline exists by geometry; neither party needs a shoulder check for the other to be seen. Well-established

Setback crossings

The bicycle crossing sits at least one car length back from the turning radius, so a turning driver completes the turn, straightens, and then meets the crossing, with a stopped car's length of reaction space between. Well-established

The American catalyst was not an agency but an explainer: Portland-based planner Nick Falbo's 2014 'protected intersection' video, viewed over 700,000 times, is widely credited with popularizing the Dutch geometry for a US audience. Salt Lake City followed Davis within months (October 2015), then Austin. NACTO's Urban Bikeway Design Guide did not originally include protected-intersection geometry; Alta Planning + Design did the adaptation work for the North American context. Well-established

The honest complication

The honest complication, from Davis's own bicycle-advocacy community: the intersection delivers its sightline benefit only to cyclists who actually use the separated path and its refuge islands. A cyclist riding the standard bike-lane approach gets a sightline no better than a conventional intersection. Protection that depends on route choice is a design gap, not a detail. Reported Single advocacy source, not independently corroborated.

The Plateau

The infrastructure is old and the measurement is institutional. Tilburg and The Hague were among the earliest Dutch cities to build dedicated cycle routes, alongside Utrecht, Groningen, Enschede, Amsterdam, and Delft, and the country has been counting its cycling ever since. Reported

17–19%

Davis, CA

The highest US bike-commute share, in the same city that built the first Dutch junction. Reported

Three decades, flat on purpose

The sharper finding: the national share has been stable for roughly three decades, not still climbing. What has grown instead is cycling frequency and average trip distance per cyclist. That complicates the reflex that success means a rising percentage. A plateau at a very high level, sustained for thirty years through fuel shocks, e-bikes, and urban growth, may be the more meaningful marker of durability than continued growth would be. Well-established

The Economics

From the peer-reviewed record only: a study quantifying the health-related economic benefits of Dutch cycling levels finds that continued investment in cycling infrastructure yields a high cost-benefit ratio, driven primarily by reduced sedentary-lifestyle disease and lower all-cause mortality risk, not by construction activity or tourism. Larger, rounder claims circulate (national jobs totals, billion-euro benefit ranges) that trace to unverifiable aggregation; they are deliberately absent from this report and this page. Well-established

Key Insights

Categories, not dials

This interactive is a card swap and not a slider because the doctrine is a card swap and not a slider: a Dutch street is classified (through-road, distributor, access road) and its design follows from the class. Safety was never a quantity you add to a street. It is a decision you make about one.

The plateau is the point

Dutch cycling has held 27–28% of all trips for about three decades. It stopped growing and refused to shrink, through e-bikes, urban growth, and every disruption since. A share that high, held that long, is a stronger durability claim than a rising curve would be.

Protection you have to opt into

Davis's own advocates note the first US protected intersection only delivers its sightlines to cyclists who use the refuge islands; the standard bike-lane approach sees no better than a conventional junction. Geometry that must be chosen is not yet a system; the Dutch versions work because there is no other way through.

The second-bicycle problem

The report's Section 8 follows the success to its logistics bill: a bike-plus-train country needs a bicycle at both ends of the ride, so the system multiplies bicycles faster than people, and station parking, not street design, becomes the binding constraint. Solved street categories buy you a new category of problem. Reported

The cards show the categories; the written field guide carries the doctrine behind them: Sustainable Safety's three principles, the retrofit history, and what the classification question would mean applied anywhere else.
