How Miami-Dade County Reduced Crashes on SW 8th Street by 10%

The In|Sync Adaptive Traffic Signal Control System has been changing the game in over 150 cities and counties across the United States. One of the areas that have recently adopted and implemented In|Sync is Miami-Dade County in Florida, specifically initiating the use of the technology on SW 8th Street.

About SW 8th Street in Miami-Dade County, Florida 

SW 8th Street receives an influx of passengers and travelers daily. It traverses two municipalities: the City of Miami and the City of Sweetwater. It provides direct access to downtown Miami, various residential and employment locations, and Florida International University. A 2018 statistic shows that the average daily traffic is 51,288 vehicles per day.  

Implementing the In|Sync Adaptive Traffic Signal Control System 

In|Sync was deployed at 30 intersections along SW 8th Street, particularly between SW 67th Avenue and SW 142nd Avenue with goals to improve the efficiency of traffic operations along the corridor, minimize congestion, increase throughput, enhance safety and mobility, and address the increasing traffic demand on SW 8th Street. 

The Results: Benefits of Implementing In|Sync

The implementation of In|Sync significantly improved travel time on SW 8th Street, reducing cross street delay by 17.3% and increasing the overall corridor throughput by 5-6%, as shown by the study conducted by Florida International University (FIU).

Data also shows a 9.7% decrease in crash frequency in the main street, as well as an 8.5% reduction in crashes in cross streets. All initial goals of the implementation project were achieved successfully, resulting in an improvement in the corridor’s efficiency and safety. 

Overall, the project of implementing In|Sync adaptive traffic signal technology along SW 8th Street greatly reduced the time in congestion along the corridor by as much as 28.5%.  

The FIU study concludes that deploying In|Sync real-time adaptive traffic signal technology has successfully fulfilled the project’s objectives and has resulted in 6:1 Benefit/Cost Ratio.
