The “modern”
roundabout has come into favour recently as an effective means
of controlling traffic at intersections. Roundabouts more
effectively minimize delay and have a better safety performance
than stop controlled intersections when it comes to high severity
collisions. The new roundabouts have improved geometric design
over the older roundabout found in North America in the 1960’s
and offer overall better performance than their predecessors
or intersections.
Included
below are two depictions of how the "modern" roundabout
works.
Take
a look at a video clip of how roundabouts work by clicking
in the centre of the diagram on the right.
You
will need Windows Media Player and audio capabilities
to view this clip which is a 17 MB AVI movie complete
with soundtrack.
We
wish to acknowledge the City of Lacey for allowing the
use of their video "Driving Modern Roundabouts",
to provide driver education as to the use of Modern
Roundabouts. Note that there will be some slight nuances
between the Washington and BC application, however the
driving principles are the same.
Watch
an animated graphic depiction of how roundabouts work. The animation shows travel through a roundabout.
It currently does not show the pavement markings with the
roundabout.
