Alabama Department of Transportation expands Iteris contract

The Alabama Department of Transportation (ALDoT) has chosen to expand its use of Iteris’ probe-based analytics service to all five ALDoT regions.

The project builds on ALDoT’s statewide roadway analytics, supported by Here Tecnologies’ traffic data, and will significantly expand Iteris’s ClearGuide Signal Trends use from 50 signals in a single region to 1,149 signals statewide.

Proactively enhance signal timings

Together, ALDoT, Iteris and Here report they will use shared insights to proactively enhance signal timings to better facilitate traffic flow statewide.

ClearGuide Signal Trends is a cloud-based performance analytics tool that uses probe data to help agencies quickly spot issues and efficiently improve operations at signalised intersections without reliance on additional field equipment or infrastructure.

“By scaling Signal Trends statewide, ALDoT is strengthening its ability to proactively manage mobility and improve the daily travel experience across the state, while also reducing the cost to deliver these improvements”

With this statewide expansion, ALDoT will gain real time visibility across all five regions, enabling staff to:

• Quickly detect and diagnose congestion, delays, and abnormal patterns
• Prioritise maintenance and timing improvements
• Manage mobility consistently for all constituents across urban and rural networks
• Reduce time and cost spent troubleshooting without driving to every intersection.

“We’re excited about the opportunity to continue to improve the operations of our traffic signals using ClearGuide through this investment with Here and Iteris,” said Brett Sellers, state TSMO engineer for ALDoT.

“Utilising the available datasets to adjust timings and follow just how impactful the adjustments are in near real-time will provide us opportunities to positively impact peoples’ lives with improved travel times and safety through efficiency.”
