Nashville's First Traffic Management Center: How NDOT Built the Infrastructure for Smart Mobility

Situation

As Nashville's population and tourism surged, so did congestion, unreliable travel times, and safety concerns on high-injury corridors like Clarksville Pike and Nolensville Pike. Long bus rides, difficult transfers, and unsafe crossings made it clear that timing-plan-only operations were no longer enough. NDOT needed a central place to see the entire network in real time and actively manage it for safety, reliability, and multimodal performance.

Challenge

NDOT's leadership identified three needs: a single operational picture of the network from downtown to suburban arterials; tools to actively manage signals and corridors in real time, not just re-time every few years; and better safety intelligence for people walking, biking, and riding transit, beyond what crash reports could show. The room had to be sized for multiple operators and partner agencies as the system scales.

Solution

Fountainhead Control Rooms delivered the NDOT Traffic Management Center as a turnkey control room, leading the project from concept to reality. We designed the layout, operator consoles, and large-format visualization so operators can quickly interpret data and coordinate responses from a shared operational picture. The room is configured to support multiple operators and partner agencies, giving NDOT space to expand as more signals, corridors, and data sources come online.

Results

The TMC opened in 2024 and anchors a 7-year program to upgrade roughly 600 signals to smart, centrally managed infrastructure — with Clarksville Pike as the first smart-signal deployment on a high-injury, transit-rich corridor. NDOT and Vanderbilt are using LiDAR and AI at seven North Nashville intersections to detect dangerous behavior before it becomes a crash, backed by a $10M U.S. DOT SMART grant. The TMC and supporting technology are funded through Choose How You Move (a $100M+ local sales-tax initiative), CMAQ funds, and two federal SMART grants totaling $12M.
