EXECUTIVE SUMMARY
This report presents the findings of the traffic calming study conducted by Marlin
Engineering, Inc. for The Grove Area located in the City of Miami, Miami -Dade County,
Florida. The study addresses residents' concerns related to traffic intrusion and
excessive vehicular speeds within residential neighborhoods. In an effort to develop a
traffic calming plan for the neighborhood, Marlin Engineering collected existing traffic
information including vehicular speed, traffic volumes, crash data for the period from
2004 to 2006, and land use. Field Observations and analysis of the data collected
identified the locations that are meeting the warrants to implement traffic calming
treatments.
After the Draft Study Report was submitted to Miami -Dade County Traffic Engineering
Division for approval, the two proposed traffic circles were approved, but none of the
proposed speed humps were approved (see Appendix C). The City of Miami called for
a meeting with Marlin Engineering, Inc. and Miami -Dade County Traffic Engineering
Division. The County agreed on the concept of changing the Narrow Street Low
Volume Traffic Calming Criteria, as the existing criteria is almost impossible to be met.
The main concept of the new criteria is, if the speed criteria is not met, a combination of
speed and cut -through could be used. The new criteria was then used to reanalyze the
collected data. The report recommendation is to install traffic calming devices at the
identified locations as shown in the table below. The proposed Traffic Circles and
Speed Humps or Single Points should reduce vehicular speeds, minimize traffic
intrusion and reduce vehicular conflicts at the identified locations. The preliminary cost
estimate for the installation of the recommended traffic calming devices is about
$195,000.
