What is ITS?

An intelligent transportation system (ITS) uses technology to improve the efficiency of all modes of transportation by using real-time data to adapt to changes in traffic flow. ITS helps with general traffic management, mobility using alternative modes of transportation, incident management related to accidents and weather, and more. The City’s goal is to enable users to be better informed to make safer, more coordinated, and 'smarter' use of the City’s streets.

What is the purpose of cameras and sensors on traffic signals?

In short, their purpose is to improve traffic flow on the City’s busiest roads.

Centennial is implementing its Intelligent Transportation System — or ITS — an integrated communications system that connects to the City’s fiber network and Traffic Operations Center. Part of this implementation involved the installation of 64 closed-circuit cameras at high-traffic intersections and travel-time monitoring equipment on major corridors. These cameras are for real-time traffic monitoring, not surveillance. 

How is the City using the information?

Recently the cities of Centennial, Greenwood Village and Lone Tree identified a pilot project to take a cross-jurisdictional approach to managing and reducing traffic congestion. Specifically, the cities are working to create a connected, data-driven, multi-jurisdictional traffic management plan for Yosemite Street between Lincoln Avenue and Belleview Avenue that promotes efficient and safe traffic flow through the installation of sensors at traffic signals. This is the first multi-jurisdictional partnership to enable adaptive signal technology. 

A private sensor vendor, Blyncsy, has secured a grant to facilitate the installation of their sensors in Centennial and Lone Tree (Greenwood Village already has similar sensors in place) to monitor traffic and collect volumes, travel times, and delay (time spent waiting at a signal). The data collected will directly serve the City’s pilot project with Greenwood Village and Lone Tree to install adaptive signal technology on Yosemite Street. This data will fully describe the existing conditions on the corridor. 

What happens next?

After the adaptive technology is deployed and the software starts making tweaks to the signal timing, participating cities can measure the effectiveness of the pilot project by comparing the before and after conditions. A successful pilot will prove emerging technology can be applied to traffic signals to benefit businesses, commuters, and residents alike, and will set a precedent for all future efforts our cities undertake.
