GEC for the Upgrade of the Existing Advanced Traffic Management System (ATMS)

The Traffic Signals & Signs (TSS) Division of the Miami-Dade County Department of Transportation and Public Works (DTPW) is currently upgrading its existing Advanced Traffic Management System (ATMS) and traffic signal controllers with a more state-of-the-art system that will better serve motorists, transit users, pedestrians, and bicyclists throughout Miami-Dade County. The Miami-Dade County ATMS system upgrade (ATMS project) is one of the largest efforts of its nature ever undertaken as a single project in the U.S.


APCTE was selected by TSS as the General Engineering Consultant (GEC) to provide project management support, construction and contract management, traffic engineering support, ITS (Intelligent Transportation System) expertise, and public involvement support for the ATMS project. The ATMS project schedule is extremely aggressive, and the contractor plans to complete the 2,900 signalized intersection in 4 years instead of the 5 years requested by DTPW. The contractor is also planning to complete 500 intersections in the first year and then 800/year over the next three years. This aggressive schedule makes this GEC contract even more important/critical. As the County’s representative, APCTE will supervise the ATMS project progress and assist them however possible to make the ATMS project a success.


More specifically, the APCTE team is in close coordination with several stakeholders to ensure the proposed ATMS Central SW complies with the latest Industry Security Standards while capable to provide all requirements for the daily operations of the traffic signals. Special attention at the oversight of the data migration to ensure that the Design Build Firm delivers a system capable to imitate current traffic operations within Miami Dade County. These tasks may involve additional research and development to ensure that the intersections will operate as intended. It is APCTE responsibility to keep track of all updates needed for both, Central SW and Controller SW, to ensure that the project schedule and milestones are achieved.


In addition to the upgrade of the existing ATMS system, the project also includes the update of the existing detection at selected intersections that will enable the capability of providing adaptive signal control technology at selected corridors as well as high-resolution data collection that will position TSS for future use of Automated Traffic Signal Performance Measures (ATSPM). As part of the GEC contract, the APCTE team will provide technical support on the selection and simulation of the adaptive corridors as well as using Business Intelligence strategies through data analysis to assist the County in their decision-making process.


Overall, the APCTE team through this GEC contract will assist TSS to set up the foundations for wider and smarter mobility initiatives in the near and long-term future.
