The Traffic Engineering Operations section performs several functions in support of Palm Beach County's Engineering and Public Works Department. These functions are summarized below:

  • Traffic Engineering Studies: Performs various studies including signal warrant analysis, speed studies, delay studies, queuing studies, pedestrian and bicycle studies, school zone limits, line of sight studies, speed hump evaluation, horizontal curve studies, roundabout operation and others. Identifies operational deficiencies, identifies potential improvements, and calculates the benefit-cost ratios of these improvements for project selection.
  • Roadway Signs and Striping: Insures roadway signs and markings are installed in accordance with County, State and National standards.  All road signs and markings must be conforming to the Manual on Uniform Traffic Control Devices (MUTCD) to insure uniformity and consistency with driver expectation.

  • Special Events Program: Event organizers that temporarily close County rights-of-way are required to maintain the safe movement of vehicles, bicycles and pedestrians during these events. The Special Events Program is responsible for administering and monitoring the permits required for special events that use County rights-of-way.  For more information on how to apply for a Special Events Permit on County right-of-way, please review the procedure and applicable application by clicking the link below:
    Special Event Permit Application Procedure andApplication
  • Pathway Program: The County Pathway Program provides sidewalk and bicycle pathways where there is a feasible need.  These pathways will be placed to provide safe routes for children between their school and home.  Recreational pathways are a secondary priority, but may also be provided as part of this program.  Pathway projects can be requested by any resident, community, Sheriff's office, and public or private organizations. 
  • Traffic Calming Program: Manages the traffic calming program intended to slow motor vehicles through the installation of geometric changes to the roadway such as speed humps on non-thoroughfare roadways.

    The Traffic Division evaluates these requests based on criteria that includes roadway traffic volume, average vehicle speed, patterns of cut through traffic, and crash history. Neighborhood consensus supporting the installation of the speed humps is also required
    . For more information, please contact the Traffic Engineering Operations Manager, Fadi Nassar  FNassar@pbcgov.org
  • Traffic Data Analysis Section: Collects peak season annual traffic data for roadway segments and intersections, identifies peak hours and truck percentages, calculates daily and peak hour volume over capacity ratios, and computes historical growth rates. This data is used to conduct various studies within the Traffic Engineering Division.
  • Traffic Safety Section: Collects crash data from various agencies and police departments. Reviews coded data for accuracy, geocodes location and saves information in a crash data program developed specifically for the County that allows efficient query and summary of crash data on roadway segments and intersections throughout the County.  Historical crash data is an important factor in identifying corrective actions and evaluating improvements.
  • Community Traffic Control Agreement: The Community Traffic Control Agreement is required for the Palm Beach Sheriff's Office to enforce traffic laws upon Community roadways in accordance with Florida State Statute 316.006,(3),(B). The Traffic Engineering Operations section reviews the required documentation and executes these agreements in coordination with PBSO. The required documentation includes a certified traffic survey submitted by a licensed traffic engineering consultant or engineering firm stating that all regulatory traffic signs and posted speeds within a community comply with applicable state and federal standards.  For more information on this process and to download the agreement template documents, please visit our Traffic Control Agreements webpage here.
‚ÄčThe Traffic Engineering Operations section performs several functions in support of Palm Beach County's Engineering and Public Works Department. These functions are summarized below:

  • Operational Engineering Studies: Performs studies to evaluate traffic operations of roadways, and intersections, identify deficiencies, analyze improvements, and calculate benefit-cost ratios of various improvements including changes to signal timing or phasing.
  • Traffic Studies: Performs various studies including signal warrant analysis, speed studies, delay studies, queuing studies, pedestrian and bicycle studies, school zone limits, line of sight studies, speed hump evaluation, horizontal curve studies, roundabout operation and others.
  • Roadway Signs and Striping: Insures roadway signs and markings are installed in accordance with County, State and National standards.  All road signs and markings must be conforming to the Manual of Uniform Traffic Control Devices (MUTCD) to insure uniformity and consistency with driver expectation.

  • Pathway Program: The County Pathway Program provides sidewalks and bicycle pathways where there is a feasible need.  These pathways will be placed to provide safe routes for children between school and home.  Recreational pathways are a secondary priority, but may also be provided as part of this program.  Pathway projects can be requested by any resident, community, Sheriff's office, and public or private organizations.  The Traffic Division Staff reviews all requests to make sure they serve the intended function, are not already scheduled for construction, and do not have apparent fatal flaw such as lack of right of way.  Cost and feasibility reports are then requested from the Roadway Production Division.  All eligible projects are forwarded to the Selection Committee for funding.  The Committee includes one member each of Traffic Division, Roadway Production Division, School Board, Sheriff's Office, MPO and Planning Department.  The committee's recommended projects are sent to the Board of County Commissioners in October for approval to be constructed in the upcoming fiscal year.
  • Traffic Calming Program: Manages the traffic calming program intended to slow motor vehicles through the installation of geometric changes to the roadway such as speed humps on non-thoroughfare roadways.

    One of the most frequently requested traffic calming roadway feature is for speed humps. The Traffic Calming Program has established criteria to uniformly evaluate requests from citizens and associations for speed humps.  Speed humps are installed on two-types of non-thoroughfare roadways under the County's jurisdiction (unincorporated areas) consisting of residential streets and residential collectors.  The evaluation criteria includes:

    • High daily traffic volumes (+1,500 for residential streets & +3,000 for residential collectors)
    • High speed (50% of vehicles in excess of posted speed limit)
    • Traffic cut-through problem greater than 10%
    • A pattern of accidents that would be addressed by traffic calming
    • Road with no fronting drives in proximity to schools, parks or recreational areas
    • Neighborhood consensus (written support from HOA, or if no HOA, petitions from 60% of homeowners on the road which driveway is within 300 feet from a proposed speed hump.
    The Traffic Division has developed standards for designing and constructing speed humps and the associated roadway striping that can be downloaded from the Traffic Division website (Speed Hump Detail ). 
  • Traffic Data Analysis Section: Collects peak season annual traffic data for roadway segments and intersections, identifies peak hours and truck percentages, calculates daily and peak hour volume over capacity ratios, and computes historical growth rates. This data is used to conduct various studies within the Traffic Engineering Division.
  • Traffic Safety Section: Collects crash data from various agencies and police departments. Reviews coded data for accuracy, geocodes location and saves information in a crash data program developed specifically for the County that allows efficient query and summary of crash data on roadway segments and intersections throughout the County.  Historical crash data is an important factor in identifying corrective actions and evaluating improvements.
  • Citizen Requests: Responds to citizen requests regarding signing, speeding, sight obstruction, delays, signal phasing and other requests. This includes documenting each request, collecting data and conducting field measurements to investigate each complaint, evaluating the situation, and taking actions necessary to enhance the safety and mobility of the County maintained roadways. If you would like to submit a request or concern, please submit these through the Engineering Action Center Engineering Action Center,  ENG-ActionCenter@pbcgov.org, 561-684-4012 or 561-684-4018.  
  • Community Traffic Control Agreement: Reviews certified traffic surveys submitted by a licensed traffic engineering consultant or engineering firm stating that all regulatory traffic signs and posted speeds within a community comply with applicable state and federal standards.  Communities can then enter into an agreement with the County to provide the County traffic control jurisdiction over private roadways within the community in consultations with Palm Beach County Sheriff's Office.  The agreement allows the Sheriff's Office to enforce traffic laws upon Community roadways in accordance with Florida State Statute 316.006,(3),(B).
