Half of US traffic cameras are not live video
Of 52,325 public traffic cameras across the United States, 24,585 stream video, about 47%. The rest publish a still image that refreshes every few minutes.
“Live traffic camera” means two different things depending on the state. Some DOTs provide video streams. Others publish a photograph every few minutes, which is useful but not live.
States that stream video on nearly every camera they publish (12): Texas, Virginia, Missouri, South Carolina, Indiana, Tennessee. States that publish almost only still images: Illinois, Washington, Utah, Ohio.

How we measured
A camera counts as video when the state publishes a playable stream for it (an HLS manifest), and as a still image when it offers only an image URL. We read this directly from each DOT's own feed; it is not inferred from the image.
States with fewer than 100 cameras are excluded from the table to avoid percentages based on a small number of devices.
How Roadze distinguishes them
Every camera is labeled: red “Live” for video and amber “Snapshot” for a refreshing photo. When you open a still camera, Roadze plays the most recent frames in sequence so that movement is visible.
