ADOT dust detection system put to the test with recent storms ABC15 and last updated 2021-07-16 21:55:13-04 Within the past week, the Valley has been hit by severe storms, producing heavy rain, damaging wind and blowing dust. Those same storms struck the I-10 corridor between Phoenix and Tucson, where ADOT's dust detection system is located. âWhat weâve done here is created a system in the area where historically we had the most dust-related traffic accidents in our state in a 10-mile section in Pinal County," says ADOT spokesperson Tom Herrmann. Since the first-of-its-kind network of sensors, signs and cameras went into operation last June, ADOT says that seven dust storms have activated the system.
