The Arizona Department of Transportation (ADOT) is installing dust-detection software along a vulnerable stretch of I-10 to prevent dust-related crashes.
New technology will detect if high amounts of dust particles are in the air that could hamper visibility. It will automatically activate warnings on electronic road signs and lower the speed limit on variable speed limit signs. Cameras will allow workers at ADOT's traffic operations center in Phoenix to monitor the situation in real time.
Installation of the new alert system is expected to finish in fall 2019. It coincides with ongoing construction to widen the interstate near Picacho Peak and build a new interchange at S.R. 87.
