A
transportation planner
is
studying user
preferences
for
alternatives
to the
Lions
Gate
Bridge
crossing.
A
questionnaire
is
designed that
specifies
three
transit
options:
widen the
bridge
(2 lanes
each way),
replace
the
bridge
with a
tunnel,
designate
one
of
the
existing vehicle
lanes
for
a
rapid transit
system.
Three
bridge
user
groups
are
surveyed:
daily commuters,
commercial
transport
operators,
and tourists.
Each user
group is
considered a
different
sample.
