US DOT Traffic Camera Statistics
No agency publishes a national count of DOT road cameras, so we built one. As of October 14, 2026, this directory tracks 22,927 official DOT road cameras across 35 states, published by 20 state DOT and 511 systems, plus 1,248 FAA aviation weather cameras counted separately (24,175 feeds in all from 21 public agencies), and we verify every feed with our own rolling HTTP checks. These are monitoring webcams, not speed or red-light enforcement cameras. Every number on this page is measured from the feeds themselves, not quoted from anyone else.
*Live share is computed over the 21,594 cameras in states our checker can reliably measure; see the camera uptime report for the full methodology and per-state reliability rankings.
How many DOT road cameras are in the US?
At least 22,927. That is every road camera the 20 state DOT and 511 systems in this directory publish that we have verified ourselves, and it is a floor rather than a total: states we have not yet added would push the real number higher. The 1,248 FAA aviation weather cameras we also track are federal and sit at airstrips and lookouts, so they are counted separately. No government body publishes a national figure, so a verified count of what the agencies themselves publish is the closest thing that exists.
The largest state camera networks
Ranked by fleet size. Some state DOTs publish cameras through a direct API, others through their official 511 traveler-information platform; both are the state's own network.
| Agency | State | Cameras |
|---|---|---|
| Georgia 511 | Georgia | 4,331 |
| Caltrans CWWP2 | California | 3,402 |
| Utah 511 | Utah | 2,082 |
| MnDOT (511mn CARS) | Minnesota | 1,948 |
| WSDOT Traveler Information API | Washington | 1,706 |
| Iowa DOT | Iowa | 1,260 |
| CDOT (COtrip CARS) | Colorado | 1,235 |
| Nebraska DOT (CARS-Hub) | Nebraska | 1,037 |
| SCDOT (511SC Iteris) | South Carolina | 791 |
| INDOT (CARS-Hub) | Indiana | 748 |
Traffic cameras by state
Camera counts cover every feed we track in the state, including federal and other non-DOT public sources. A small count means we have not added that state's DOT network yet, not that the state runs few cameras. These numbers grow as we add networks. Live share appears only where the fleet is big enough and our checker can reliably measure it; for the rest we show the count and withhold the percentage rather than publish a number we do not trust.
| State | Cameras | Verified live share |
|---|---|---|
| Georgia | 4,331 | 83.4% |
| California | 3,406 | 76.6% |
| Utah | 2,098 | 96.7% |

Where these numbers come from
- Every camera in the count comes from an official public source: a state DOT, a 511 traveler-information system, or a federal program. We do not count private or unofficial cameras.
- Counts include only active cameras; retired and delisted feeds are excluded the day they are removed.
- Every feed is health-checked on a rolling schedule around the clock, which is how the live-share figures are measured. Full methodology on the camera uptime report.
- The total is a floor, not a ceiling: states and agencies we have not yet added are missing from it, so the true national number is higher.
- This page regenerates continuously from the live database; there is no annual snapshot to go stale.
How many traffic cameras are in the US, counting every type?
Nobody can say, because "traffic camera" covers several unrelated systems and only one of them is publicly countable:
- DOT road-monitoring webcams, the kind on this page: 24,175 tracked and verified here, with public image or video feeds anyone can check.
- Enforcement cameras (speed and red-light): no public feeds exist, so no one outside the operating agencies can count the devices. GHSA tracks which states permit them and IIHS lists the communities running programs, but those are law and program tallies, not camera counts.
- City traffic-management cameras, operated by municipal traffic departments: some cities publish feeds, most do not, and no central inventory exists.
So any single "total traffic cameras in the US" figure you see is either one of these categories or a guess. The number on this page is the measurable one.
