Dust Detection and Warning System

Overview

Summary

Arizona, while known for beautiful weather, has a unique section of I-10 where fields of loose dirt and high winds create massive walls of dust. These conditions dramatically reduce visibility for motorists in a matter of minutes, which has caused 83 dust-related crashes in only a five-year period with three of those crashes involving fatalities. With an overall goal is to enhance awareness, mitigate traffic delays and reduce crashes due to low visibility dust events, ADOT deployed an early warning dust detection warning system along a 10-mile segment of I-10 near Eloy, Arizona that uses remote sensing equipment to automatically control speed limits during periods of low visibility.

In this case study you will learn: 

  1. How ADOT deployed an early warning dust detection warning system along a 10-mile segment of I-10 that uses remote sensing equipment to automatically control speed limits during periods of low visibility
  2. How ADOT brought together a team of equipment suppliers, engineers, software programmers, IT staff, and system operators to meet the challenge of integrating sensors, software, and motorist information outputs into one seamless automated system.
  3. About how data and a dashboard are being generated that will provide useful information for future applications.
