Calming Program Warrants |

We
are often asked why is IT necessary that specific warrants must
be met for many of the various traffic requests we receive.
The Federal Government, the State of Florida, and the City of
Sarasota have established warrants for the safety and convenience
for all users of the public roadway system. Imagine for a moment
if there were no warrants. If for every stop sign, traffic signal
or traffic calming request installation was unquestioned and
imminent? Surely IT is better that guidelines exIT which justify
certain actions. Warrants must be met to obtain traffic calming
measures for your neighborhood.
|
|
We
ascertain Traffic Calming warrants by using traffic count data,
field studies, and Police reports.

The
Local Residential Difference
Traffic
Calming requests most often are for our local residential
streets. And most concerns tend to be about speeding traffic.
With that in mind, traffic calming for local residential
streets within the City of Sarasota is determined by the
following point system:

So what does IT all mean?
Major Collectors
Streets
designated primarily as neighborhood and arterial roadway
links.
Minor Collectors
Streets
designated primarily as inter-neighborhood roadways.
Local Residential
Streets
designated to provide access to individual homes.
Daily volume or AADT
Average
annual daily traffic counts; counts are seasonally adjusted.
Cut thru traffic calculation
The
AADT volume minus the # of trips (# of homes on a block x
10) divided by the volume
85th percentile speed
85%
of the drivers are traveling at the speed or less; 15% are
traveling at greater speeds.
Traffic Calming: Terms & Definitions
Traffic
Calming Measures are design elements in and/or along the
street or intersection that conform to the definition of traffic
calming.
Streetscaping includes planning and placing distinctive
lighting, furniture, art, trees, and other landscaping along
street and at intersections. Is not considered traditional
traffic calming.
Traffic Control Devices are signs, signals and markings
designed to regulate, warn, guide, and provide information.
Examples include stop signs, speed limIT signs and traffic
signals.
Neighborhood
Traffic Calming Plans are plans for whole neighborhoods.
Area-wide Traffic Calming Plans are for large areas
such as two neighborhoods.
Traffic Management/Route Modifications are a combination
of measures that alter the available routes for traffic or
traffic flow. Examples include diverters and one-way streets.
Street Modification Plans involve more than one street
and include traffic calming elements, route modifications,
traffic control devices, and alternative modes of transportation
such as bike lanes and sidewalks.
