== Design and publications ==

The Dutch not-for-profit organisation CROW publishes design manuals summarizing best standards for bicycle infrastructure in the Netherlands, where biking is a much more dominant mode of transportation than in the United States.<ref>{{Cite web|url=https://www.crow.nl/english-summary|title=About CROW – CROW|website=www.crow.nl|access-date=2019-02-27|archive-date=2024-05-15|archive-url=https://web.archive.org/web/20240515051509/https://www.crow.nl/english-summary|url-status=dead}}</ref><ref>{{Cite web|url=https://www.vox.com/science-and-health/2018/8/28/17789510/bike-cycling-netherlands-dutch-infrastructure|title=No helmets, no problem: how the Dutch created a casual biking culture|website=www.vox.com | date = 28 December 2018 | access-date = 12 October 2022}}</ref> The organisation's and country's longer experience with synthesizing biking and driving transportation modes have made CROW's design manual internationally popular. After decades of publications in the native Dutch, an English translation was released in 2017.<ref>{{cite web|url=https://www.crow.nl/publicaties/design-manual-for-bicycle-traffic-(1)|publisher= CROW| title = Design manual for bicycle traffic | date=2017}}</ref><ref>{{cite web | url = https://usa.streetsblog.org/2017/02/01/the-dutchs-beloved-bikeway-design-manual-just-got-an-update/ | publisher = Streetsblog USA | title = The Dutch's Beloved Bikeway Design Manual Just Got an Update | website = usa.streetsblog.org | date = 1 February 2017 | access-date = 12 October 2022}}</ref>

=== US Design Guide Controversy ===

Line 93:

In 2011, the primary North American planning organisation NACTO released new design guidelines which claimed to use international best practices while omitting Dutch best practices. This sparked controversy, especially after ambassador of Dutch bicycle infrastructure Mark Wagenbuur criticised NACTO for doing so in a prominent trade blog.<ref>{{cite web|url=http://www.aviewfromthecyclepath.com/2011/04/state-of-art-bikeway-design-or-is-it.html |title= blog post: State of art bikeway design, or is it? |publisher=A view from the cycle path| date = 7 April 2011}}</ref> Three years after the furor, Nick Falbo, then part of Alta Planning + Design, a firm behind the NACTO designs, published ‘protectedintersection.com’, which integrated more European design concepts.<ref>{{cite web|url=http://www.protectedintersection.com|title=Protected Intersection|publisher=Nick Falbo| date = February 2014 |access-date=8 January 2015}}</ref>

In 2015, Alta Planning + Design published schematics and some realisations of "protected intersections" in the US and Canada closer to Dutch practice.<ref name="PI evolution">{{cite web |url=https://altaplanning.com/wp-content/uploads/Evolution-of-the-Protected-Intersection_ALTA-2015.pdf | title= Evolution of the Protected Intersection |publisher= Alta planning+design |date=December 2015 |access-date=2019-02-21 |archive-date=2019-07-15 December |archive-url=https://web.archive.org/web/20190715173213/https://altaplanning.com/wp-content/uploads/Evolution-of-the-Protected-Intersection_ALTA-2015.pdf |url-status=dead }}</ref> Later in the year, the [[Massachusetts Department of Transportation]] released their Separated Bike Lane Planning and Design Guide, which includes extensive discussion of protected intersections, and was used as a pilot for the upcoming [[American Association of State Highway and Transportation Officials|AASHTO]] Bike Guide.<ref>{{Cite web|title=AASHTO Guide for the Development of Bicycle Facilities, 2020|url=https://tooledesign.com/project/update-to-the-aashto-guide-for-the-design-of-bicycle-facilities-2019/|access-date=2021-02-13|website=Toole Design|date=9 February 2018 |language=en-US}}</ref> In 2019, NACTO, whose original Urban Bikeways Design guide generated the controversy, released "Don't Give Up at the Intersection", which encourages protected intersections as an alternative to bicycle lane drops. In 2021, the [[Infrastructure Investment and Jobs Act|Invest in America Act]] became law, which amended the federal Highway Safety Improvement Program to recognize "protected intersection features" along with other separated bikeway treatments.<ref>{{Cite web |date=2021-11-15 |title=H.R.3684 – Infrastructure Investment and Jobs Act SEC. 11111.
