FY26-DDOT-TSA-Traffic Signal System Modernization Phase 2 (Construction)

The District of Columbia Department of Transportation is preparing to execute a comprehensive modernization of the city’s traffic signal infrastructure through a large-scale, citywide deployment of advanced traffic signal control systems. This initiative involves replacing all existing traffic signal controllers with next-generation units and implementing a new central traffic signal management system designed to integrate emerging transportation technologies. The goal is to significantly enhance traffic safety, improve multimodal mobility for vehicles, pedestrians, and cyclists, increase operational efficiency, and maximize the return on investment in transportation infrastructure. The project, designated as FY26-DDOT-TSA-Traffic Signal System Modernization Phase 2 (Construction), represents a major upgrade to the city’s transportation network and is currently in the forecasting stage, with the solicitation expected to follow. Although specific details such as funding sources, contract timeline, and award criteria have not been published, the scope clearly indicates a transformative effort requiring coordination across all neighborhoods and intersection types throughout the District. The modernized system will likely enable real-time adaptive signal control, data-driven decision making, and seamless integration with other smart city platforms to support long-term transportation resilience and sustainability goals.
