Statewide Traffic Signal System Updates with Cloud‑Based ITS and Connected Vehicle Technologies
The Statewide Traffic Signal System Updates project shows how the Maine Department of Transportation upgraded traffic signal systems across the state with cloud‑based ITS, modern controllers, and connected vehicle technology. Econolite helped provide cabinets, network engineering, cloud ATMS, and systems integration, so the upgraded signals now support real‑time operations and future smart mobility needs.
Project Background
In 2021, the Maine DOT began a design‑build program to reconstruct 104 signalized intersections across the state. Because the existing systems were aging and inconsistent, the agency needed a statewide solution that could improve traffic flow and safety. As part of that effort, modern ITS integration and connected vehicle capabilities were key to future‑proofing the traffic network.
Statewide Deployment
To meet these goals, Econolite provided a complete range of solutions including:
- New ATC signal cabinets and Cobalt® controllers with EOS firmware
- Cloud‑based Centracs® Mobility ATMS for centralized traffic management
- Network engineering and communications upgrades
- Field systems configuration and systems integration
- Connected vehicle technologies and advanced ITS tools
Because these systems were deployed statewide, the Maine DOT can now manage signals more consistently, share real‑time data, and support adaptive operations over the cloud. With advanced modules like Signal Performance Measures, the agency also gains tools for pattern optimization and adaptive signal control.
Key Features of the System Updates
- Cloud‑based traffic management with Centracs® Mobility
- Modern ATC cabinets and Cobalt® controllers
- Connected vehicle technology support
- Enhanced network communications
- Signal performance analytics and optimization
Operational Benefits
As a result of this statewide update, Maine DOT can now:
- Monitor signals centrally in real time
- Improve traffic flow consistency across regions
- Support connected vehicle and smart mobility applications
- Use analytics to make data‑driven timing decisions
- Plan future upgrades more efficiently
Overall, this project modernized Maine’s traffic signal infrastructure and gives the state a scalable cloud‑based ITS platform for future innovations. Additionally, it positions the system for better support of connected vehicles and advanced traffic management strategies.
