FY26-DDOT-TSA-Traffic Signal System Modernization Phase 1 (Construction)

The District of Columbia Department of Transportation is preparing to initiate Phase 1 of a citywide modernization effort to replace all existing traffic signal controllers with advanced models and implement a new central traffic signal management system. This initiative aims to enhance traffic safety, improve multimodal mobility for vehicles, pedestrians, and cyclists, and increase operational efficiency across the entire city’s signal network. The system will integrate emerging transportation technologies to optimize signal timing, reduce congestion, and improve infrastructure return on investment through data-driven decision making and real-time adaptive control capabilities. The project is scoped as a large-scale deployment, indicating a comprehensive overhaul of the current infrastructure rather than incremental upgrades. This forecasted contract, titled FY26-DDOT-TSA-Traffic Signal System Modernization Phase 1 (Construction), is scheduled for release in fiscal year 2026 with a posting date of July 23, 2026. While specific details such as solicitation number, NAICS code, set aside provisions, and point of contact are not yet available, the effort is clearly positioned as a major capital investment by the city’s transportation agency. The place of performance is the entire District of Columbia, reflecting a citywide scope, and the project will likely involve extensive coordination with city departments, public stakeholders, and contractors to ensure seamless implementation while minimizing disruption to daily traffic patterns.
