Item I

Re: Traffic:Lane Arrangement at Pitt River Fd./
Shaughnessy Intersection

Alderman Keryluk through Co‘incil had asked for a look
at the north appreach to the above intersection because ofa
hazard to traffic resulting from two lanes going through the
intersection at the same time. The Committee looked at alter-
natives for the treatment of this intersection including the
marking of two separate lanes and the widening of .the south
side to allow a separate left turn on both the north and the
south sides. YThe Committee recommends the alternative shown
in the attached Sketch Ne. © which results in the north
approach being reduced by painted lines on the pavement to
one lane. The advantage of this treatment over the others is

that backed up traffic is kept clear of the right turn lane
and that the through lane lines up with the road on the other
side of the intersection. It also eliminates the hazard of
having two vehicles going straight through the intersection at
the same time and trying to merge at the other side of the
intersection. The disadvantages are that through traffic is
delayed by left turning traffic and the capacity of the
approach'is reduced. It was felt that the installation of
traffic signals at the intersection of Mary Will Road and
Pitt River Road would reduce the amount of through traffic at
this intersection and therefore the effects of this proposed
restriction would not be too great. As it will be some time
before we can do any painting on the roads anyway, the other
signals will probably be in before this work can be done.
