<b>protected junction</b>, also known as a <b>Dutch-style junction</b>, is a type of <a href="/wiki/Intersection_(road)" title="Intersection (road)">at-grade road junction</a> in which <a href="/wiki/Cycling" title="Cycling">cyclists</a> and <a href="/wiki/Pedestrian" title="Pedestrian">pedestrians</a> are separated from cars. The primary aim of junction protection is to help pedestrians and cyclists be and feel safer at road junctions.<sup id="cite_ref-Butler_1-0" class="reference"><a href="#cite_note-Butler-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>At a conventional junction, pedestrians are separated from motor vehicles, while cyclists are placed in the <a href="/wiki/Carriageway" title="Carriageway">carriageway</a> with motorists. Cycle lanes are often placed on the nearside (right in <a href="/wiki/Right-side_driving_countries" class="mw-redirect" title="Right-side driving countries">right-side driving countries</a>; left in left-side countries) of the carriageway, which can create conflict, for example when a cyclist is going straight ahead and a motorist is turning to the nearside.<sup id="cite_ref-Butler_1-1" class="reference"><a href="#cite_note-Butler-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>At a protected junction, vehicles turning to the nearside are separated from crossing cyclists and pedestrians by a buffer, providing increased reaction times and visibility. Drivers looking to turn to the nearside have better visibility of cyclists and pedestrians as they can look to the side for conflicts instead of over their shoulders. At unsignalised intersections, it is practice to have one car length of space between the cycleway and roadway, so that cars exiting the minor street have an area to pull forward and wait for a gap in traffic, without becoming distracted by potential simultaneous conflicts along the cyclepath. </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:13-06-27-rotterdam-by-RalfR-25.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/4/4a/13-06-27-rotterdam-by-RalfR-25.jpg/220px-13-06-27-rotterdam-by-RalfR-25.jpg" decoding="async" width="220" height="146" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/4/4a/13-06-27-rotterdam-by-RalfR-25.jpg/330px-13-06-27-rotterdam-by-RalfR-25.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/4/4a/13-06-27-rotterdam-by-RalfR-25.jpg/440px-13-06-27-rotterdam-by-RalfR-25.jpg 2x" data-file-width="4288" data-file-height="2848" /></a><figcaption>A protected intersection in <a href="/wiki/Rotterdam" title="Rotterdam">Rotterdam</a> in the <a href="/wiki/Netherlands" title="Netherlands">Netherlands</a>.

An alternative philosophy, design for <a href="/wiki/Vehicular_cycling" title="Vehicular cycling">vehicular cycling</a>, encourages having bicycle lanes simply disappear, or "drop", at intersections, forcing riders to merge into traffic like a vehicle operator ahead of the intersection in order to avoid the risk of a <i>right-hook</i> collision, when a right turning motorist collides with a through moving cyclist.

(2006) utgjorde slike ulykker 68% av alle sykkelulykker i flerfelts rundkjøringer. Ifølge Cumming (2012) skjer mange slike ulykker fordi bilister ikke så syklisten, noe som forklares med at mange syklister sykler ytterst i rundkjøringen.
