Traffic Engineering

Traffic engineering is the analysis involved in traffic planning, design and operations. The County evaluates day-to-day traffic concerns, performs traffic engineering studies and makes recommendations and design plans for the installation of traffic control and calming devices. The goal is to improve the mobility, safety and capacity of Miami-Dade County’s infrastructure, including:

  • Investigating requests for new or additional traffic control devices and perform traffic studies countywide, as well as resolving concerns in response to requests from governmental agencies and the general public.
  • Investigating hazardous traffic conditions and making recommendations for the installation of traffic control and calming devices countywide.
  • Collecting traffic data used to monitor traffic patterns and trends countywide.
  • Developing design plans for the construction of projects, such as intersection improvements, new signals, school zone flashers and general signing and pavement markings.
  • Reviewing and approving traffic engineering components of all construction design and site plans from all public and private sources, including Maintenance of Traffic reviews and permit applications for paving and drainage plans.
  • Reviewing and approving traffic impact studies and site plans for public and private schools.
  • Reviewing and approving studies in conjunction with Developments of Regional Impact (DRI), the Development Impact Committee (DIC) and development orders for public hearings, plats and permits for compliance with the State Growth Management Act for traffic concurrency.
