, . To provide continuity for research, items are in agenda order although not
necessarily discussed in that order.
The Chair called the meeting to order at 4:05 p.m. at City Hall.
ITEM #1 - Approval of Minutes
Member Moran moved to approve the minutes of the regular meeting of October 16,
200.0, as submitted in written summation to each board member. The motion was duly
seconded and corrled unanimously.
ITEM #2 - Old Business
In response to a committee request, Traffic Operations Manager Paul Bertels
submitted the weekly summary for February 8, 1997, listing the hourly traffic counts for
Poinsettia before the roundabout was constructed.
Lt. John Slack said the Police Department in September had received 3 calls on
roundabout accidents but issued no reports and in October received 1 9 calls and issued 6
reports. Since the roundabout opened"only one injury has been reported.
It was requested the spreadsheet be modified to reflect funds spent to date on
tweaking the roundabout.

ITEM #3 - Final Review of Questions Presented
Discussion ensued regarding questions to ask Barry Crown.
ITEM #4 - Conference call with Barrv Crown

, In response to a question, Mr. Crown said an example of small changes resulting in
a large benefit would be new stripin'g, which was inexpensive but reduced accidents. He
said widening the radius 'at the Coronado entry from 10 to 12 feet will increase capacity
and safety. He said the roundabout's original design had narrow lanes and small entry and
exit radii to severely control traffic speeds and improve the safety of large volumes of
pedestrians. Problems resulted when traffic volumes were highe( than anticipated. He said
his proposal to widen access points will allow large trucks to maneuver, except to the
Marina. He said widening the causeway approach east of East Shore would be very
expensive and not very helpful.

Mr. Crown said adding a third lane for north beach destinations would be expensive,
rarely used, and of little benefit. Northbound vehicles already can exit at East Shore. He
said the geometry of proposed changes to access points will increase capacity on the
causeway by 55%, on Mandalay by 44%, and on Coronado by 38%. He said his
predictions are based on the Rodel modeling program, developed in the UK (United
Kingdom). He said the program, costing more than $11-million to develop, is extremely
accurate. He will forward his computations to staff and a copy of the modeling program
results. He said the aaSfDRA program is based on the gap theory and does not properly
measure the geometry or capacity of roundabouts.

In response to a question, Mr. Crown said the proposed alignment for Mandalay
complies with standards and is designed to control the speed of vehicles entering the
roundabout. He said without access points at Poinsettia and the Marina, the roundabout
could have been circular in shape and comply with the American guide. He said drivers
checking roundabout traffic when entering from Mandalay will turn their heads to an angle
similar to when entering a "T" intersection. He said his recommended changes will
increase capacity of traffic egressing from Mandalay and decrease delays. He said an
increase of 3 to 5 miles per, hour is not enough speed to endanger pedestrians. The farther
a crosswalk is from the roundabout, the more space traffic has to increase speed before
reaching it. Staff will need to monitor the situation. Concern was expressed the proposed
changes will endanger pedestrians. It is important for vehicles to be aware of pedestrians,
and visa versa.

In response to a question, Mr. Crown said the proposal to remove the lower two
steps of the fountain would reduce the "canyon" affect, but its $125,000 cost may not
provide value, The fountain currently does not affect visibility nor necessary sight lines.
He suggested moving only the lower step would help some and move the fountain 6 inches

farther from traffic lanes. He agreed changes to the fountain shoufd be delayed until all
other recommended changes are tried.

: Mr. Crown said enlarging the roundabout to the size of one in Vail, Colorado would
be oxtromely expensive, requiring all access points to be redesigned and the vault to be
moved. He said the only benefit would be to move the road away from the fountain. He
said it would be less expensive to modify the fountain. He said widening circulating roads'
'. would cause more accidents. He said the intensity of traffic traveling through the Vail
roundabout is much less than in Clearwater. He said while most in the UK are not striped,
the City's roundabout requires striping. He said bad striping causes accidents. He said the
roundabout's geometry and striping are interrelated, He said problems at Coronado are due
to geometry. Once that is repaired, the striping will be redone.

Concern was expressed use of the access points differ, making it difficult to
educate drivers on USing the roundabout. Mr. Crown said differences relate to volume
requirements for 2-lane entries and exits on Mandalay, Coronado, and the Causeway. The '
Marina only needs one lane. He said traffic volumes are too great on Mandalay to narrow
its access to one fane. Mr. Crown reviewed his recommendations to remove the traffic
signal at Coronado a,nd Gulfview, indicating traffic movement improvement will reduce
backups into'the roundabout. He stated another option would be to reduce private vehicle
access to Clearwater beach and provide alternative transportation. He felt that option
would discourage tourism.

In response to a question related to yielding requirements, Mr. Crown said traffic
circulating through the roundabout has the right of way. He said accidents occur when
vehicles move side by side. Discuss'ion ensued regarding driver courtesy and which driver
is at fault after an accident. It was suggested the yield sign off Mandalay should indicate
its warning refers to both lanes of roundabout traffic. Mr, Crown said instructors who
teach drivers to stay in the outside lane are wrong. It was suggested a radio signal could
instruct drivers on correct roundabout movement.

~oncern was expressed installing a crosswalk across the causeway in front of the
Marina would be dangerous. The recommendation is for a traffic signal to be long enough
to cross halfway to the median. Doubt was expressed that pedestrians would wait safely
on the median for the traffic signal to change again and instead would cross during a gap in
traffic. Mr. Crown said the median would be widened. It was suggested pedestrians be
directed to the walkway under bridge 43. Mr. Crown felt pedestrians would not walk from
the Marina or Poinsettia to the bridge to cross the causeway. Staff estimated 1 ,000
pedestrians a day crossed the causeway during last year's Spring Break. It was suggested
stronger enforcement would help. Mr. Crown noted the difficulty of redirecting pedestrian
movement.

Mr. Crown said the illumination of the roundabout after dark i5 not good when the
fountain lights are off. He recommended the City increase lighting to meet standards in the
federal highway guide. Aelated costs have not been estimated. It was suggested the
committee work to create realistic expectations.

ITEM #5 - New Busine~i
The Chair indicated the committee had adopted rules that members who miss three
consecutive meetings can be removed from the committee. He said Member Brown had
missed three successive meetings. Member Casey will miss three meetings in a row in
. November.. She has suggested she could participate via a conference telephone call.' She
, said when she agreed to serve on the committee, it had been indicated that weekly
meetings ~ould not extend into November. ,It was suggested either the rule be waived or
enforced. The Chair will contact Member Brown regarding his plans. The committee will
. discuss this issue further on November 6, 2000. Staff will consult the City Attorney
r.egarding a conference telephone call being ~al1owed.
'j .
! "
Cost estimates fo~ changes to the roundabout recommended by Mr. Crown will be
available on November 10, ,2000. Staff will not make recommendations until that time. A
limited time is available to complete changes prior to Spring Break. Lt. Slack said the
Police Department could handle Spring Break without the changes in place if overtime costs
,can be covered. Ms; Arasteh said even with related construction interference last year, the
movement of Spring Break traffic had improved over previous years.
