The Indiana Department of Transportation (DOT) oversees the investment of more than $2 billion in 1,300 road construction projects and preventative maintenance activities in 2021. To improve work zone safety, Indiana DOT is deploying three new systems across Indiana’s roadway system. Queue Trucks equipped with high visibility warning lights and portable message boards warn motorists of slow or stopped traffic as they approach roadway work zones. Automated Queue Warning Systems accurately detect queued traffic and relay that information to portable and responsive message signs to transmit warning messages to drivers upstream of the work zone. Haas Alert Systems send real-time digital alerts to Waze when first responders or construction crews are on-scene with emergency lights activated. Motorists receiving these notifications have more time to slow down and/or move over.
