Miami-Dade County installs and tests first adaptive traffic signals

MIAMI (November 02, 2016)

This week, Miami-Dade County’s Department of Transportation and Public Works (DTPW) took another step towards improving mobility as it began testing the County’s first adaptive traffic signals.

Installed on NW 36 Street, between 71st and 84th avenues, this smart traffic signal technology will help to further improve traffic flow, signal synchronization, and reduce congestion.

The adaptive signals will automatically change signal-timing to improve traffic flow and keep signals synchronized as conditions change throughout the day. Equipped with cameras, they are designed to monitor the intersections and reprogram their own timing to respond more quickly to changing conditions.

“Traffic signal synchronization is a top priority for my administration. Miami-Dade County is investing $40 million in 2017 for the implementation of the adaptive signal system throughout major corridors. This is part of a five-year, $160 million effort to improve traffic signalization and reduce congestion throughout our County,” said Miami-Dade County Mayor Carlos A. Gimenez.

Smart traffic controllers can detect when vehicles are backing up at a red light and can automatically change the signal’s timing to balance the throughput at the intersection; thus, keeping traffic flowing more smoothly.

DTPW plans to install more adaptive signals at major intersections and corridors countywide within the next year, as part of a larger five-year plan to improve mobility in Miami-Dade County. The new signal equipment will also give priority to Metrobuses that might be traveling in heavy traffic in order to improve reliability for transit services.

This summer, the Department unveiled the modernized Traffic Management Center, where transportation engineers oversee new traffic monitoring cameras and are improving the synchronization of signals. They use information from Waze, cameras, and other traffic speed data feed, to improve traffic flow. This process has already yielded mobility improvements. For instance, along US-1, the daily congested hours have been reduced by 25 percent, and the northbound travel time from SW 152nd Street to SW 16th Avenue has also been reduced by an average of 10 minutes.

“Only a year ago, we had to send engineers out into the field to monitor traffic and manually change signal timing. Today, these new adaptive signals can detect where traffic is becoming congested and adjust their own timing to maximize traffic flow and operational efficiency,” said DTPW Director Alice N. Bravo, P.E. “We encourage people to use programs like Waze to help improve traffic flow by sharing real-time traffic and road information while avoiding congested locations.”
