FY26-DDOT-TSA-Traffic Signal System Modernization System Management (Engineering Services)

The District of Columbia Department of Transportation is planning a comprehensive modernization of its traffic signal infrastructure through a citywide deployment of advanced traffic signal controllers and a new central management system. This initiative aims to replace all existing legacy controllers with next-generation hardware capable of integrating emerging transportation technologies to enhance traffic flow, reduce congestion, and improve safety for all road users including pedestrians, cyclists, and public transit. The project encompasses both hardware upgrades and the implementation of a centralized software platform to monitor, manage, and optimize signal timing dynamically across the entire city network, increasing operational efficiency and infrastructure return on investment. Engineering services will be required to support the design, integration, testing, and deployment of this modernized system, ensuring seamless interoperability with existing transportation networks and future-proofing the city’s traffic management capabilities. The effort is scoped to deliver comprehensive improvements in multimodal mobility, with a focus on reducing delays, lowering emissions, and supporting equitable access to transportation. While specific procurement details such as set-aside status or NAICS code are not yet defined, the forecasted contract is anticipated to trigger formal bidding in FY26, with work performed citywide under the oversight of DDOT.
