Provider families
Many transportation agencies publish data through shared traveler-information platforms. WAC documents these at a high level so users can understand why similar source behavior appears across multiple states.
Castle Rock
Castle Rock-powered traveler maps commonly provide camera metadata and recent imagery for state 511-style maps. WAC treats these as agency-published traveler information and normalizes camera locations and image freshness where implemented.
TravelIQ
TravelIQ-powered traveler maps appear across multiple state and regional 511 services. WAC uses these sources for camera coverage where the public map data supports location and image display.
Travel Midwest
Travel Midwest is a regional traveler-information source used for Illinois camera coverage in WAC. Its data is represented as a regional source rather than a single-state agency feed.
Iteris
Iteris-backed traveler-information feeds can include camera and road-weather station imagery. WAC uses them where the configured source provides enough location and image metadata for public map display.
Agency-specific feeds
Some agencies publish their own data feeds or GIS layers outside a shared provider family. WAC documents those sources by agency and data category, while omitting low-level access details.
