About Courses
Dutch Style Roundabout design
Dutch Style
Roundabouts
are one of
the most
innovative
roundabouts
that provide
priority to
pedestrians
and cyclists
without
significantly
compromising
vehicular
traffic
movement.
Our Dutch
Style
Roundabout
course
modules are
designed to
cover all
key aspects
of the
design
process. It
covers the
centreline
design of
all four
arms, crown
line of
Roundabout,
and then
gradually
develops
road
channels,
cycle
tracks,
footway,
crossing
facilities,
etc.
The first
module
starts with
verification
of the
Topographical
Survey.
Here, the
module
explains how
to verify
the topo
survey and
make it fit
to use as
Xref for
roundabout
design. The
module also
explains how
to change
the colors
of
individual
layers to
make Xref
less
prominent.
The second
module
explains the
design
process of
Roundabout
crown line,
road
centrelines,
channel line
design,
entry radius
design, exit
radius
design,
splitter
island
design. The
proposed
layout set
the
foundation
of the
roundabout
footprint so
that footway
and cycle
facilities
are provided
safely.
The third
module
explains the
design
process of
cycle
facility
design. A
circulatory
uni-directional
cycle track
is designed.
Inbound and
outbound
cycle tracks
are designed
and
connected to
the
circulatory.
The fourth
module
explains the
process of
footway
design and
crossing
facilities.
The back
edge of the
footways
plays an
important
role in
tie-into the
existing.
Segregated
pedestrian
and cycle
crossing
facilities
are
proposed. It
is highly
recommended
to provide a
pedestrian
crossing
facility
suitable for
blind and
partially
sighted
pedestrians,
therefore
tactile are
proposed at
all crossing
points.
The fifth
module
explains the
process of
creating a
General
Arrangement
Drawing. The
module
details out
how to call
all required
Xrefs and
how to use
sheet
layout,
title frame,
etc to
develop
General
Arrangement
Drawings.
Finally, the
module
explains how
to create a
PDF of the
General
Arrangement
drawing.
