Bunting power point crosswalk safetyPresentation Transcript
The purpose of this paper will be to
determine the best pedestrian traffic
control device to install on the 27
crosswalks on Fort Myers Beach, in
order to increase pedestrian safety by
encouraging drivers to yield to
pedestrians in the crosswalk.
T Town of Fort Myers Beach
The town was created in 1995.
The town is run by a town council consisting of a
mayor, a vice mayor, and 3 council member.
The town employs a town manager, an
administrative assistant, a town clerk, a contracts
manager, and a receptionist.
The town has an annual budget of 28,656, 308

In the past year, four
pedestrians have been
killed while crossing Estero
Blvd at crosswalks.
According to former
Mayor Larry Kiker, there
were 24 pedestrian
accidents on the island last
Estero is a very busy road
with major traffic
during the tourist season.
There has been a 20
percent increase in the
number of pedestrian
accidents this year (Kiker,
The main cause of this problem is congestion.
Visitors are on vacation and do not pay attention when they
cross the road.
They walk out in front of traffic assuming the drivers will
stop because they are in a crosswalk.
Likewise, the drivers are also on vacation and are paying
attention to their surroundings, rather than the people in the

Miami Case Study
Miami has one of the highest pedestrian fatality
rates in the state.
In order to solve this problem, the city set up
research teams to explore different
countermeasures that could be used in the city to
help make it a safer place for pedestrians.
These included “intelligent video pedestrian
detection devices” and rapid flash beacons
The results showed that some of the
countermeasures worked very well, while others had
no significant effect on the behavior of the drivers or
In Miami the use of the RRFBs increased the
percentage of drivers who yielded to the pedestrians
quite a bit.
At site #1 the yielding rate went from 0 percent to
65 percent. At site #2, the rate went from 1
percent to 92 percent.
Seattle Case Study
City leaders were not
happy with the fact that
398 pedestrians were killed
The city began installing
overhead crosswalk signs at
their busiest crosswalks.
Before the signs were installed, the driver yielding rate was
After the signs were installed, the driver yielding rate went
up to 52 percent.
The crosswalk signs were also effective in improving the
behavior of the pedestrians in the crosswalk.
Before the signs were installed 58 percent of the pedestrians
“ran, aborted, or hesitated” in crossing the road.
After the signs were installed, this rate went down to 43%.
Lakeland Case Study
Lakeland, Florida is located in Polk County where there
were 13 pedestrians killed last year (Parody, 2013).
The city has tried to improve the safety of the pedestrians in
crosswalks by installing “flashing crosswalks.”
This device embeds lights into the roadway on both sides of a
When a pedestrian approaches the crosswalk, he or she will
see a button to push that will turn on the flashing lights.
The flashing lights are designed to warn approaching drivers
that someone is waiting to cross the road.
The flashers were effective
in increasing the number of
drivers who yielded to
Before the flashers were
put in, the percentage of
drivers who yielded to
pedestrians was 15.8
After the flashers were
installed, the rate went up
to 41.0 percent.
Lit Review One
Huang, Zegeer, and Nassi (2000)
Studied three different traffic control
systems that have been employed in various
locations to make it safer for pedestrians to
cross the road.
Safety Cones in New York
Pedestrian Activated Flashing Amber
Stop for Pedestrians in Crosswalks signs.
Results Huang, et al (2000)
The device that
produced the most
consistent results was the
pedestrian safety cones.
Before the cones were
put up, 69.8 percent of
the drivers yielded to the
After the treatment, this
rate went up to 82.1
Lit Review Two:

Lit Review Four: Do, et al (2011)
The purpose of this study was to identify some
countermeasures that could make crosswalks safer for
The countermeasure study included RRFB, HAWK,
Shared Lanes, and Crosswalk Markings.
Results showed signals were effective in reducing
accidents by 69 percent.
The type of marking made a difference.
Bar pairs and continental markings were most effective.
Lit Review Five:

Yellow light changes from flashing to solid.
Alerts drivers to stop.

Alternative 2: HAWK
Overall reviews were good
but there were two issues
with this system.
The dark beacons are hard
Some people think it is a
broken traffic light and
Cost is 80,000 dollars.
Medians are areas between lanes of traffic.
Raised medians are the most effective but they cost
anywhere from 15,000 to 30,000 dollars per 100 feet.
The road also needs to be wide enough for the raised
Alternative 3-Flashing Crosswalk
Flashing crosswalks are a series of flashing lights installed just
below the pavement surface.
They warn motorists that pedestrians want to cross.
Cost is 15,000 to 18,000 dollars.
They increase the yielding rate from 16 percent to 92
The purpose of the ARP was to provide the best solution
to a problem in a public service organization.
The project was designed to use a quantative
methodology to select the most effective traffic control
device to improve pedestrian safety on Fort Myers
The comparative analysis will determine which of the
four traffic devices studied will be the best choice for the
Town of Fort Myers Beach.
Selection of Best Alternative
The quantative and comparative analysis
concluded that the best alternative for Fort Myers
Beach is the flashing crosswalks.
Alternative 4 scored 172 points.
The rectangular rapid flashing beacon came in
second with 166 points.
The raised medians was third at 146.
HAWK system came in last with 145.
Year One-Set up control crosswalks using only zebra stripes
to determine which 10 crosswalks will get the treatment.
YearTwo-Determine the total cost and work with Lee
County to secure funding and install the treatment on the 10
crosswalks that were chosen.
YearThree-Begin the evaluation process which will compare
the crosswalks with and without treatment to determine if
the system is effective.
Year Four- If the system is effective, install it in the
