Advanced Traffic Management System (ATMS) Program

Building the Infrastructure for Better Mobility

• Project’s Importance

  This project is part of the county’s broader initiatives aimed at building the foundation for both near and long-term mobility improvements. 
  
  The project replaces outdated technology by updating the traffic signal infrastructure, including new traffic signal controllers and detection devices. 
  
  The County’s new traffic management system will adhere to industry-wide standard data communications protocols, allowing the County to support smart city initiatives at intersections that could benefit from it. This includes features such as two-way communication between vehicles and traffic signals and adaptive traffic control systems. 
  
  The new enhanced capability to collect high-resolution data will position the County for future use of Automated Traffic Signal Performance Measures (ATSPM). ATSPMs will facilitate the County’s effort to move away from reactive management that responds to problems as they are reported, and toward proactive management that takes action based on direct measurement of performance.

• ATMS Benefits

  • Optimized Operation
    The ATMS project upgrades will lay the foundation for a more versatile operation by enabling support for complex signal functions and streamlining the configuration of traffic signal controllers. The upgrade to the ATC controller provides a significant boost in computing processing power, memory capacity, and a more intuitive interface at signalized intersections enabling more efficient and sophisticated traffic management.
  • Improved Network Performance
    ATC controllers will enhance detection capabilities, including detection of motorists, public transit users, bicyclists, and pedestrians, improving overall mobility and safety. ATC systems will allow the collection and management of real-time high resolution traffic data, providing valuable information for proactive traffic management and decision-making.
  • Resources Integration
    ATC controllers provide an open architecture hardware and software platform that can support a wide variety of Intelligent Transportation Systems (ITS) applications including traffic management and other applications. ATC controllers can facilitate the sharing of traffic data with other systems, enabling more integrated and coordinated traffic management approaches. Furthermore, the new ATC Controller fully integrates into the counties existing signal cabinet infrastructure, leveraging existing resources. 
  • Safety
    The ATMS project will contribute to Miami-Dade’s Vision Zero goal of eliminating traffic-related fatalities and serious injuries by 2040. The project scope includes recalculation of traffic safety parameters such as yellow clearances, red clearances, pedestrian clearances and railroad track clearances ensuring that values meet or exceed current standards.

• Project Tasks

  The following project tasks will occur on a parallel path.

  • New central software & deployment of new hardware
    Upgrades to the central software system at the County’s Traffic Management Center for the support of a new generation of standardized Advanced Traffic Controllers (ATC) and deployment of new ATC traffic signal controllers at all signalized intersections.
  • Detection systems
    Design and construction of detection systems at signalized intersections.
  • Advanced traffic engineering solutions
    The implementation of the new Advanced Traffic Management System (ATMS) software and Advanced Traffic Controllers (ATC) establishes a robust foundation to support the evolving advancements in traffic signal operations. This modernization not only enhances current system capabilities but also ensures the infrastructure is well-positioned to integrate future innovations, improve operational efficiency, and meet the increasing demands of intelligent transportation systems.

• Project Schedule

  In October 2024, Miami-Dade County awarded a new ATMS contract to Horsepower Electric. This next phase of the project is slated for completion over a 10-year period. Building on the lessons learned from the previous effort, the County has placed renewed emphasis on accountability, stakeholder engagement, and delivering reliable, forward-looking solutions that align with Miami-Dade’s long-term transportation goals.

• Frequently Asked Questions

  What is the Advanced Traffic Management System (ATMS) Project?
  The Advanced Traffic Management System (ATMS) Project includes the upgrade of the County’s ATMS Central Control Software, replacement of approximately 3,000 controllers, and installation of additional detection systems at selected county’s signalized intersections.
  
  What are the benefits of the ATMS Project?
  Optimized Operation. The new standardized ATC traffic controllers and detectors, in conjunction with the upgrades to the ATMS Central Control Software, will allow traffic engineers to optimize signal operations, with the goal of reducing wait times and improving traffic operations and safety. Upgraded signalized intersections will allow for faster adaptability to current traffic conditions in a more automated fashion.

  
  How much disruption will residents experience during construction?
  During construction, there will be intermittent lane closures to allow overhead detector installation work to be done at some intersections. While the new controllers are being installed, law enforcement officers will be on-site to direct traffic.
  
  Replacements at large and busy intersections will take place during the night to minimize impact, while intersections with relatively low traffic volumes may be replaced during the day. The location of detection installation will dictate the time of day or night for installation. Whether installed during the day or night, lane closures will be off-peak (for example, 9 a.m. to 3 p.m. or 9 p.m. to 5 a.m.). Lane closures on Fridays will generally be later, from 11 p.m. to 6 a.m. Lane closures are only envisioned for those intersections receiving new detection systems. 

  What is the project schedule?
  The contractor, Horsepower Electric, is currently conducting testing and certifications of the technologies and solutions planned for deployment under the ATMS project. This preparatory phase is essential to ensure system reliability and long-term performance. Full-scale implementation is scheduled to begin in March 2026.
  
  The project scope of work includes the following tasks and their total duration:
  

  • Installation of an upgraded central software system at the County’s Traffic Management Center (1 year)
  • Controller Upgrades: Replacement of obsolete controllers with new traffic signal controllers at all signalized intersections while maintaining current system operations (5 years).
  • Detection Systems Installation: Design and construction of detection systems for up to 600 signalized intersections (7 years). 

  These tasks will occur on a parallel path. Project completion is expected within 10 years.
  
  How can I stay informed about the project in my area?
  To ensure timely access to accurate information, the following tools and communication channels are available:
  

  • Interactive Project Tracker Map – Provides real-time updates on current installation status and planned future work
  • Public Feedback Channels – Submit questions or comments via 311 or by email at [email protected]
  • Partner Agency Coordination – Municipalities and elected officials may request a project presentation by contacting [email protected]

  These resources are designed to keep the community and stakeholders informed throughout the duration of the project.
