<p>A <b>quadrant roadway intersection</b> adds an additional "quadrant roadway" between two legs of an <a href="Intersection_(road)" title="Intersection (road)">intersection</a>. This roadway adds two <a href="Three-way_junction" title="Three-way junction">three-way intersections</a> in addition to the original four-way intersection, moving all left turns (in <a href="Right-_and_left-hand_traffic" class="mw-redirect" title="Right- and left-hand traffic">right-hand traffic</a> countries) or right turns (in <a href="Right-_and_left-hand_traffic" class="mw-redirect" title="Right- and left-hand traffic">left-hand traffic</a> countries) from the main intersection. The design is intended to improve traffic flow by reducing signal timing phases from four to two in the main intersection. The design is intended for intersections where large artery routes meet in an area of dense development and high pedestrian volume.<sup id="cite_ref-dot_1-0" class="reference"><a href="#cite_note-dot-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-carynews_2-0" class="reference"><a href="#cite_note-carynews-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>

</p><p>Proponents also point to a reduction in places where accidents could occur from vehicles potentially crossing paths, as well as a low development cost compared to <a href="Roundabout" title="Roundabout">roundabouts</a> or the more complex <a href="Single-point_urban_interchange" title="Single-point urban interchange">single-point urban interchange</a> designs.<sup id="cite_ref-dot_1-1" class="reference"><a href="#cite_note-dot-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-ncsu_3-0" class="reference"><a href="#cite_note-ncsu-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-idaho_4-0" class="reference"><a href="#cite_note-idaho-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> Opponents point to the increase in points where accidents could occur with merging traffic as well as the non-traditional nature of the design, which has the potential to confuse drivers. Opponents also rebut low-cost claims, pointing to right-of-way and construction costs of the quadrant road.<sup id="cite_ref-dot_1-2" class="reference"><a href="#cite_note-dot-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-ncsu_3-1" class="reference"><a href="#cite_note-ncsu-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>

</p><p>A related structure known as a <a href="Jughandle" title="Jughandle">jughandle</a> accomplishes similar traffic movement from a more compact shape.

<p>Single-quadrant intersections (pictured above) feature a single quadrant road.

</p><p>A <b>double-quadrant intersection</b> (or <b>two-quadrant intersection</b>) adds a second quadrant road placed opposite another.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>
