In addition, 56 Miami-Dade traffic lights have been updated to become “smart” traffic lights that instantly adjust red-green timing to drive traffic as fast as possible.

County officials signed a $ 150 million contract with Siemens Mobility last summer to upgrade all 2,600 signals to adapt to traffic. This process will take about 7 years.

“Currently, Alice Bravo, Director of the Public Utilities Board, said in an email:” The Department is working on the planning and engineering phase of the (project). During this phase, the system Includes development of elements in the back room and field survey of intersections. “

“On February 2, the construction, engineering, and inspection team contract awards to support the county on this project were approved by the County Commission,” she continued.

Covid-19 has delayed work, but she said the central signal software will be tested online by spring, allowing the county to interface with new controllers and signals.

“Smart Signals,” division spokesman Luis Espinosa told Miami Today last summer. “You can quickly adjust the timing of traffic lights according to traffic conditions and speed. As traffic increases and travel speeds slow down, the system adjusts the amount of green light time in each direction to flow traffic. Improve. “

To date, Bravo said 347 sensors have been updated. Last August, Miami Today reported that this number was 291. Bravo says that when central software becomes operational, 15 signals will be upgraded each week. She said the upgrades are done “seamlessly” to avoid interfering with traffic.

A Siemens study predicted an average 15% reduction in travel time, but Bravo said the data was not yet available.

“Although traffic has increased recently, there is still a lot of variation in daily traffic due to the continuous changes and impacts of the Covid-19 pandemic. Therefore, the department will determine the most aggressive approach and time frame for conducting future traffic surveys of adaptive signals. “
