From YouTube: Roundabout Construction Part 1 of 3
Description
Produced in 2003, this program shows the design and construction process in the building of Bend's first roundabouts. There are now nearly two dozen roundabouts in the City of Bend.
A
Welcome
to
city
additions,
the
city
of
bend's,
video
news
magazine,
featuring
programs
and
policies
of
our
city,
government,
hello,
I'm,
Laura,
rumpler,
the
city's
Communications
Manager,
and
in
this
video
we're
going
to
take
a
unique
look
at
a
component
of
our
transportation
system.
Roundabouts,
the
city
of
Bend,
received
numerous
inquiries
both
regionally
and
nationally
about
this
innovative
approach
to
transportation
and
moving
our
traffic
through
our
community.
That
is
both
effective
and
aesthetically.
Pleasing
the.
B
City
of
Bend
Oregon
selected
the
use
of
roundabouts,
after
studying
it
for
a
long
time
to
come
up
with
a
solution
that
was
a
diversion
from
our
standard.
4-Way,
stop
lights
and
four-way
stops
something
that
would
keep
traffic
moving,
something
that
was
aesthetically,
pleasing
and
environmentally
friendly.
The
city
of
Bend
has
created
this
video
to
not
only
educate
our
own
citizens
on
the
use
of
roundabouts
and
why
we
employ
them,
but
to
also
assist
other
cities
and
the
many
questions
that
we
have
regarding
why
we
built
around
about
how
efficient
are
they?
B
C
City
of
Bend
primarily
became
interested
in
roundabouts
because
of
the
safety
benefits,
as
well
as
the
visual
benefits.
There
are
a
lot
more
attractive
than
a
traffic
signal.
One
of
the
disadvantages
of
a
traffic
signal
is
you.
You
need
to
have
auxiliary
lanes,
you
need
to
have
left
turn
pockets
and
sometimes
right
turn
pockets,
and
sometimes
you
also
need
to
widen
the
approach
just
to
handle
the
stacking
that
the
signal
needs,
whereas
the
roundabout
we
can
go
with
the
single
lane
approaches
and
keep
things
really
compact
and
have
one
lane
approaches
along
the
corridor.
The.
D
E
Private
developers
were
the
ones
that
brought
it
to
the
brunt.
The
city
and
the
first
one
that
went
in
Colorado
and
century
was
a
privately
the
funded
project,
SDC
reversible,
but
it
was
a
privately
funded
project
and
the
I
believe
it
was
Brookes
resources.
Mike
Halloran
was
the
one
that
took
the
bull
by
the
horns
and
got
that
one
through
all
the
red
tape
and
whatnot.
There
was
a
lot
of
opposition
to
roundabouts
before
that.
Well,.
F
We'd
seen
them
in
Europe
and
I'd
served
in
the
Transportation
Commission
before,
and
it
looked
at
these
roundabouts
in
the
proper
location
as
being
an
ideal
solution
for
traffic
and
safety.
So
we
did
go
to
the
state
and
the
state
Oh
doubt
is
a
very
effective
and
good
bureaucracy,
but
it
doesn't
make
decisions
really
quickly.
So
it
took
us
some
period
of
time
to
convince
odot
that
they
wanted
to.
Let
us
build
the
first
roundabout
on
the
state
highway
in
the
state
of
Oregon.
G
I
think
through
Mike's
travels
on
the
East
Coast
and
in
Europe
is
experienced
with
roundabouts.
He
had
visualized
how
they
could
be
applied
here
in
in
Bend
and
actually
odot,
as
well
as
federal
highway
had
been
doing
a
lot
of
research
on
the
use
of
roundabouts
as
a
traffic
control
measure,
and
so
we've
been
interested
in
the
concept
of
roundabouts
on
the
state
highway,
but
hadn't
really
found
a
location.
Yet
where
you
know
we
wanted
to
dive
in
and
and
actually
implement
that
strategy.
So
really
this
was
an
opportunity.
The.
H
West
side
traffic
consortium
is
a
group
of
developers
and
public
institutions,
including
cocc,
and
the
pen
lépine
school
district,
who
had
applications
pending
at
the
city
for
land
use,
and
this
was
in
1999
and
the
volume
of
those
applications
brought
the
city
to
a
point
of
bringing
us
all
together
to
talk
about
West
Side
traffic
improvements
and
all
the
applications
were
for
the
west
side,
and
so
this
consortium
was
was
brought
together
as
through
necessity,
to
address
the
transportation
deficiencies
on
the
west
side.
We.
F
Had
a
vision,
those
of
us
who
were
talking
about
it
in
the
West,
Side
consortium
and
other
is
actually
the
Friends
of
been
world.
Well
in
the
idea
that
if
we
could
keep
band
west
of
the
river
free
of
traffic
lights,
it
would
do
a
number
of
things.
First
of
all,
roundabouts
or
traffic
circles
work
better
when
they
are
working
in
conjunction
with
each
other
than
they
do.
G
Of
the
reason
why
the
intersection
at
century
drive
in
Colorado
presented
such
a
nice
opportunity,
one,
it's
a
district
level
highway
for
was
a
district
level
highway
for
us,
which
simply
means
it's:
it's
primarily
local
traffic.
It
functions
more
of
a
local
arterial
than
a
than
a
part
of
the
state
highway
system,
a
lot
of
repeat
traffic
and
return.
Traffic
and
Colorado
had
been
developed
in
a
rather
progressive
design
style,
with
the
raised
planted
median
the
single
lane
in
each
direction
and
the
pedestrian
facilities,
and
so
you
know
this
sort.
B
C
I
Of
conflict
in
an
intersection
are
simply
opportunities
for
a
collision
and
in
a
signalized
intersection.
We
can
count
how
many
opportunities
there
are
how
many
spots
there
are
where
such
a
collision
might
occur
and,
of
course,
we're
most
concerned
about
those
opportunities
where
they
overlap
with
the
crosswalk
there's.
C
32
conflict
points
at
a
standard,
foreleg
intersection
versus
a
data
roundabout.
So
that's
one
quarter.
The
number
of
conflict
points
and
each
conflict
point
is
simpler,
for
the
driver
to
handle
cars
are
always
circulating
in
the
same
direction
and
you're
always
approaching
a
conflict
from
the
same
spot.
They.
J
A
signalized
intersection
oftentimes,
you
come
to
it
when
there's
not
anybody
coming,
and
you
have
to
wait
for
the
phase
to
go
through
before
you
can
enter
and
go
through
the
intersection
and
around
about
it
adjusts
automatically.
You
can
go
through
it
with
ease
if
nobody's
there,
and
when
you
have
traffic,
you
wait
for
your
gap
and
just
enter
as
you
as
you
have
opportunity
to
go
through
and.
C
There's
also
some
speed
advantages
on
the
roundabout,
and
that
also
contributes
to
its
safety.
The
the
approach
speeds
on
roundabouts
are
about
15
miles
per
hour
here
in
bed
and
you're
much
less
likely
to
have
a
collision
at
that
speed,
and
if
you
do
have
a
collision,
it
is
a
much
milder
collision.
We're.
K
I
think
is
around
about
it's
certainly
very
creative.
It's
very
cutting
edge.
I.
Think
that
part
appeals
to
too
many
in
terms
of
being
on
the
cutting
edge
up
in
terms
of
technology,
but
I
think
there's
a
sense
of
rapid
growth
and
being
able
to
respond
quickly
to
growth
and
that's
really
another
advantage
of
roundabouts.
They
can
be
installed
fairly
quickly
and
in
60
to
90
days,
which
is
a
lot
of
times
twice
as
fast
as
commercial
intersection
improvement.
