It is important that everyone takes the time to do the online North
Avenue survey.
With about 50 taking the survey as of Sunday it is clear that every
“thumbs-up thumbs-down” counts and there are dozens of chances to make specific
comments.
The North Avenue online survey numbers and comments as of Sunday already
show support for cycle track from end-to-end with roundabouts at two of the
four intersections where a roundabout option is available. About 50 people had taken the survey at that
point. Generally, marked bike lanes and
“buffered bike lanes” (a bike lane with
a lines about two feet wide to separate the cyclist from the vehicle travelway)
got solid thumbs down along every segment and some form of cycle track given
thumbs up—since generally there were three types of cycle track it was not
possible to conclude one design over another—each received a several vote
positive response.
Hopefully the online survey and Workshop results will be provided in
separate tabulations. The roundabout
numbers as of Sunday were: Plattsburgh Ave 9 thumbs-up 16 thumbs-down; Ethan
Allen Parkway 23 up, 14 down; VT 127 32 up 17 down; and Institute Drive 18 up
20 down. In a comment suggesting a
roundabout at Shore/Heineberg 10 up 19 down.
Considering there are no busy street roundabouts in Chittenden County
and one mile of cycle track (raised) only on Dorset Street in South Burlington
acceptance and support for these new treatments is quite encouraging.
Between Shore Road/Heineberg Road
to VT 127—Exiting Left with Roundabouts
One set of important comments express concern about how vehicles can
exit Killarney, Village Green and Saratoga (all between Ethan Allen Parkway and
VT 127). with roundabouts in place. One set of street segment options creates three
vehicle lanes with the middle one a turn lane while intersection options include roundabouts at VT 127 and
Ethan Allen Parkway. Unfortunately the
roundabout choice is in the “intersection” set and the three-lane is separate
in the “street segment” set. In
isolation neither works to maximum performance—but together very effective. With the three
vehicle lanes (the middle one for turns) and roundabouts at both intersections, these combined options make
a left hand turn quite easy--a left hand turn involves crossing just one lane onto the middle
“turn” lane and when the far lane is clear moving into it. Yes, the traffic will not “platoon” with a
roundabout as it does to an extent today with signals in place, but traffic
will be moving at 10-20 miles an hour and in no one is in a hurry, nothing like today’s “race to the
green” routine behavior.
Finally, these turns—and speed constraints—improve with bike lanes,
preferably on both sides, as this results in better sight line to make that move
to the center lane. In many instances
traffic will yield to those wanting to complete a left turn from the middle
into the travel lane. And, there is
always the easy right-turn option and no more than a block or two in order to
use the roundabout to reverse direction, obviously not available today. During much of the day left turns can be made
by just finding the frequent “joint gaps.”
