Miami-Dade County activates 38 adaptive smart signals to improve travel time for commuters along Miami Gardens Dr. and U.S. 1
Commuters along a portion of Miami Gardens Dr. and U.S. 1 should start seeing more green lights and saving travel time thanks to the new adaptive smart signals that the Department of Transportation and Public Works (DTPW) has installed on these roads.
This week, DTPW activated seven adaptive smart signals on Miami Gardens Dr. from NW 87 Avenue to Bob O Link Drive; and thirty one signals on U.S. 1 North, from SW 98 Street near the Dadeland South Metrorail station to SW 16 Avenue near I-95.
Smart signals rapidly adjust signal timing according to traffic conditions and speeds. As traffic volumes increase and travel speeds decrease, the system will make adjustments to maximize the number of vehicles getting through the intersection, while synchronizing with other signals along a corridor to augment the number of green lights drivers experience. This is called adaptive signal control, which helps to prevent congestion and quickly alleviates it if occurs.
“The County is installing 300 smart signals, along with Transit Signal Priority (TSP) controllers, as part of a larger five-year, $160 million effort to improve mobility along the County’s ten busiest corridors,” said Miami-Dade County Mayor Carlos A. Gimenez.
Once fully installed and activated, TSP will be able to communicate with DTPW Metrobuses as they approach intersections equipped with 2070LX controllers and provide signal prioritization, allowing for a smoother, and more seamless bus ride during peak commuting hours.
“To date, 284 of the 300 traffic signals along the ten corridors have been upgraded with smart signals, and we have already activated 38 on two of the busiest roads in Miami-Dade County, Miami Gardens Dr. and U.S. 1, in order to help improve travel time and reduce congestion on those key corridors,” said Alice N. Bravo, P.E., Director of the Department of Transportation and Public Works. “As we move forward with the completion of this project and activation of 300 smart signals as well as TSP controllers, drivers and Metrobus passengers will start to see improvements on the amount of time they spend commuting from point A to point B.”
TSP and smart signals are already yielding positive results in two of the ten corridors. For example, Metrobus passengers traveling on two of Miami-Dade County’s most widely used bus routes, 34 Express and 39 Express, are enjoying shorter travel times thanks to TSP technology added to 46 traffic signals along the South Dade TransitWay. Data has shown a travel time savings of approximately 17 minutes for Route 34 Express, which runs for 20 miles, from Florida City to the Dadeland South Metrorail station, down from 67 minutes 50 minutes. Buses along the South Dade TransitWay travel on dedicated bus lanes, allowing buses to bypass traffic along U.S. 1.
Studies along the NW 36 Street corridor, conducted in 2016 when the first smart signals were installed, demonstrated a 10 percent reduction in travel time along the corridor that runs from 71 Avenue to 84 Avenue.
Once completed, 300 intersections along 10 of the County’s most traveled roadways will be equipped with smart signals and TSP. The corridors are:
• NW 36 Street – between 71 and 84 avenues
• Miami Gardens Dr. (NW 183rd Street) – from Red Road to NW 79 Avenue
• NW 163rd Street – from U.S.1 to NE 10 Avenue
• Indian Creek Drive – between 63 and 81 streets
• Biscayne Boulevard – from NW 11 Terrace to NE 82 Street
• West Flagler Street – from Le Jeune Road to Milam Dairy Road
• Le Jeune Road – between SW 8 Street and NW 14 Street
• SW 27th Avenue – between West Flagler and NW 20 streets
• SW 88th Street – between U.S. 1 and Krome Avenue
• U.S. 1 – between SW 16 Avenue and SW 98 Street, and also
• U.S. 1 – between SW 104 and 195 streets (including the South Dade TransitWay between Florida City and the Dadeland South Metrorail station)
