Traffic Signals & Signs
Traffic signal operations and maintenance
The Miami-Dade County Traffic Control Center (TCC) contains one of the country's largest centralized traffic signal control systems. The original system was installed over a 10-year period beginning in 1975 and set the standard by which most computerized signal systems were installed throughout the country.
It monitored and controlled 2,000 traffic signals on all major arterials in Miami-Dade County for decades. Between 2005 and 2010, it was replaced with an Advanced Traffic Management System (ATMS), which enabled further traffic flow improvements at all of the County’s 2,800 traffic signals.
The TCC is also home to the TS&S Division’s traffic signal operations staff. Using the aforementioned system, Signal Operations Engineers adjust the operation of the traffic signals to maximize the safety and throughput of vehicles and pedestrians to cater to demands as they change throughout the day and from day to day. Special patterns are also implemented to maximize the flow of traffic into and out of special events.
Traffic Signal field and bench technicians are on duty at all times to attend to any routine or emergency maintenance problems that arise with the system or the individual signalizations.
