An
intersection is the
junction (that is to say, on the same level) of two or more roads either meeting or crossing. An intersection may be
three-way (a
T junction or
Y junction – the latter also known as a
fork if approached from the stem of the Y), four-way (often in the form of a
crossroads), or have five (a
5-points) or more arms. Busy intersections are often controlled by
traffic lights and/or a
roundabout.
