Customer Wildfire Example
In 2017, Arizona DOT used RadioSTAT to keep motorists informed about 2 wildfires. The DOT borrowed 2 portable RadioSTAT stations from the State’s Department of Emergency Management / Bureau of Land Management to get critical information to I-17 drivers about danger and closures. Portable changeable message signs were brought onsite to direct drivers to the 1650 and 1690 AM signals. The Department updated the radio stations' programming via cellular modem gateways from their offices, so motorists are kept apprised of the fires' status.
