Transportation Defined: Loops

Loops are embedded in the roadway, two per lane, 18' apart.

There's a lot of useful information to be obtained from our roadways and loops help ADOT collect some of that data.

Loops are detectors embedded in the roadway to detect vehicle movement. These devices permit ADOT to determine traffic counts, density and vehicle speed.

This information helps traffic engineers make decisions and feeds ADOT AZ511.gov.
