NTTA’s TollGuard operations center monitors 5,900 roadside assets; staff demonstrate camera, analytics tools
Summary
NTTA IT Roadway staff described TollGuard, an in‑house operations center that monitors tolling and ITS systems, detailed monitoring tools including Nagios and VESViewer, and showed how a camera strike incident was identified and resolved.
NTTA IT Roadway staff on May 21 presented TollGuard, an internal operations center that monitors tolling and ITS systems and more than 5,900 roadside assets.
Dan Robicheaux, introducing the item as an IT Roadway presenter, said he was proud of the team and that the agency maintains its own lane systems: “I always held NTTA in highest regard because they're doing something that none of the other agencies are doing.”
Corey Carr, lane systems support manager for IT Roadway, described TollGuard as “an advanced operations center with a team of specialists and analysts designed to monitor tolling and ITS systems to ensure they are functioning correctly and efficiently and analyze data from these systems to identify trends and optimize performance.” Carr walked the board through the TollGuard ecosystem, naming core devices—CCTV and tolling cameras, lane controllers, UPS units, HVAC and toll tag readers—and the principal monitoring and analytics tools, including Nagios for system monitoring and a custom GIS‑integrated map linked to ServiceNow and MicroStrategy.
Carr demonstrated a map interface that provides a 30,000‑foot overview and a 500‑foot toll‑gantry zoom with direct links to device views and street‑view images for technician orientation. He said TollGuard uses a Video Enforcement System viewer (VESViewer) to monitor live camera feeds and described improvements after installing newer toll cameras, including better daytime and nighttime plate reads through higher resolution, improved contrast, remote focus and remote zoom capabilities.
Carr recounted a specific incident where a piece of cardboard from a trailer struck a tolling camera moments before a gantry, causing the camera to lose license‑plate reads. TollGuard analysts flagged the degraded image quality, dispatched technicians, and required a short closure and realignment to restore operations. Carr said next steps include refining procedures, targeted training, updated executive dashboards, lifecycle replacement planning for roadside systems, and pilots of predictive analytics and AI for tolling optimization.
Directors thanked the team for the presentation and several board members praised the operational visibility the new center provides.
