Traffic Management Center

monitors with traffic displays for the ITS room

Centennial Public Works is committed to delivering excellent traffic management services for everyone traveling in and through the City. With a newly expanded Traffic Management Center (TMC), the City uses Intelligent Transportation Systems (ITS) to improve roadway safety and mobility while enhancing operational efficiency.

ITS uses sensors, communications technology, and advanced electronics to implement traffic improvements in a strategic and coordinated way. These tools include advanced traffic signal controllers, weather stations, pan-tilt-zoom cameras for traffic monitoring and real-time adaptive traffic signal operations.

Data collected through these systems is synthesized in the TMC where traffic operations professionals monitor traffic flow, identify and make real-time adjustments to improve efficiency. ITS is a key component of the City’s Smart City/Smart Community initiatives, which use data-driven technology to manage City assets and resources more effectively, resulting in improved mobility, enhanced service delivery and a stronger and more connected community.

In 2017, Centennial deployed its first adaptive signal system and sensor network to adjust signal timing in real time based on changing traffic patterns and volumes. The system continues to serve as a foundational component of the City’s ITS Master Plan(PDF, 5MB).

Since the initial implementation, the City has expanded adaptive signal operations through a phased approach to include these corridors:

  • Arapahoe Rd.
  • Dry Creek Rd.
  • Jordan Rd.
  • Smoky Hill Rd.
  • Himalaya Rd.

Traffic Management Center Operations

The TMC serves as the central hub for monitoring and operating Centennial’s traffic signal system. The network includes more than 90 traffic signals, approximately 65 closed‑circuit television cameras, video detection cameras, and other field devices operating on a dedicated Ethernet network, separate from the City’s main network.

A dedicated fiber‑optic communication system connects this infrastructure, allowing staff to access reliable, real‑time information from across the roadway network.

This data is used to:

  • Monitor traffic conditions on City streets
  • Ensure proper operation of traffic signals
  • Provide information to roadway users when available
  • Adjust signal timing to support safe and efficient travel
  • Implement strategies to reduce congestion and improve air quality
  • Inform long‑term transportation planning through detailed analysis
  • Support sustainable transportation and smart‑city initiatives

Maintaining a real‑time view of roadway activity allows the City’s traffic team to respond quickly and proactively, often identifying and resolving issues before they affect the traveling public.

By combining technology, data-driven decision making, and continuous oversight, the TMC ensures the City’s roadways are safe, reliable and efficient for everyone who travels throughout the community.
