New gate arms are now in service at select intersections along the South Dade TransitWay to improve safety for the new Metro Express buses. Learn more.
The Traffic Signals and Signs Division (TS&S) of the Miami-Dade County Department of Transportation and Public Works (DTPW) is responsible for operating and maintaining traffic control devices and street lighting on the County’s arterial street network. Traffic control devices include:
Traffic Signals
Signing
Pavement Markings
School Zone Flashing Beacons
Warning Beacons
Rectangular Rapid Flashing Beacons
Electronic Speed Feedback Signs
The TS&S Division is responsible for the operation and maintenance of nearly 3,000 traffic signals throughout Miami-Dade County. The County’s traffic signals are operated and monitored from the Traffic Management Center (TMC) via an Advanced Traffic Management System (ATMS).
Miami-Dade County’s TMC hosts one of the country's largest centralized traffic signal control systems. The original system was installed in 1975 and set the standard by which most computerized signal systems were installed throughout the country. In the 2000s, the County’s traffic signal control system was upgraded to an ATMS which provided additional tools that enabled county engineers to enhance vehicular traffic flow.
The TS&S Division is currently installing a new, state-of-the-art ATMS that will better serve motorists, transit users, pedestrians, and bicyclists throughout Miami-Dade County. The County’s new traffic management system will comply with industrywide data communications protocol which will allow the County to support smart city initiatives such as two-way communication between vehicles and traffic signals.
This trailblazing project includes the upgrade of the County's ATMS central software, replacement of traffic signal controllers and additional detection systems at signalized intersections. The enhanced system will use algorithms to process data collected from motorized and transit vehicles, pedestrians, and bicyclists to optimize mobility for all transportation system users.
Project completion is anticipated in 2028.
Look up signalization plans, signal operation plans (SOP), current signal timing and other signalization documents for traffic control devices within Miami-Dade County.
The Signalization Design Manual and Signalization Standard Details are intended for personnel involved in the design and review of signalization plans, as well as signal operations pertaining to the traffic signal system maintained by Miami-Dade County.
