A dynamic message sign in Washington, DC

DDOT Centralized Dynamic Message Signs

Washington, DC

District Department of Transportation

KCI was tasked by the District Department of Transportation (DDOT) to provide construction management and inspection services for the installation of eleven new dynamic message signs (DMS) on numerous interstates and highways in and around the District of Columbia.

These installations were necessary in order to bring the District’s highway signing into compliance with the National Transportation Communication for ITS Protocol (NTCIP). The DMS structures serve to provide notice of upcoming traffic conditions, incidents that affect the traveling public, and unusual traffic circumstances.

The work was performed in phases in order to minimize disruption and limit the duration of lane closures. Our construction management team assumed a proactive stance to aggressively anticipate potential problems and develop solutions before any of the sign locations were adversely impacted, acting as an extension of the DDOT to help ensure the timely and accurate flow of information between team members. KCI was additionally responsible for furnishing, installing and testing National Transportation Communication for ITS protocol-compliant LED DMS, including the support structures, galvanized rigid steel (GRS) conduit and cabling, and associated equipment cabinets.
