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.
