INDOT_logoThe Indiana Department of Transportation is leveraging innovations in technology and equipment to reduce the risk of crashes in work zones as a record-setting 2021 road construction season begins in Indiana. INDOT Commissioner Joe McGuinness joined law enforcement and road construction contractor partners for a work zone safety showcase to highlight efforts being made to make work zones safer as INDOT continues to deliver Governor Eric J. Holcomb’s Next Level Roads plan, which invests $60 billion in improving existing roads and finishing major projects over 20 years.

INDOT will deliver nearly 1,300 construction projects in 2021, a record for a single construction season.  When combined with preventative maintenance activities, the state is investing more than $2 billion in road construction in 2021.

“Hoosiers will once again see more orange barrels than ever before across Indiana this construction season,” INDOT Commissioner Joe McGuinness said. “Those barrels are a sign of the progress we’re making to build and maintain our transportation system so that communities continue to grow and prosper and people can travel safely and conveniently across the state. Those orange barrels are also a reminder to slow down and pay extra attention in work zones to make sure people who work in and drive through our work zones stay safe.”

In 2019, a multi-agency task force was formed and several innovative solutions were tested during the 2020 construction. Following positive results from research conducted in partnership with the Joint Transportation Research Program, INDOT will be deploying back of queue warning trucks, automated queue warning systems, and the Haas alert system in work zones this season.

  • INDOT Queue trucksQueue Trucks are equipped with high visibility warning lights and portable message boards to warn motorists to be prepared to slow down or stop when approaching a work zone. Queue trucks can be moved closer to or further away from a work zone depending on the length of queue to ensure that motorists are warned of slow or stopped traffic at the appropriate intervals.
  • INDOT Automated queus warning systemsAutomated Queue Warning Systems are a work zone intelligent transportation systems comprised of a set of roadside speed sensors and portable changeable message signs (PCMS). The system has a customizable speed threshold to accurately detect queued traffic. This information is then relayed to portable and responsive message signs that transmit warning messages to drivers upstream of the work zone.
  • INDOT HAAS Alert SystemHaas Alert System sends real-time digital alerts to Waze when first responders or construction crews are on-scene with emergency lights activated. Drivers that receive these notifications have more time to slow down and/or move over.
