INDIANAPOLIS — INDOT is currently working with Purdue University on a study utilizing automated flagger assistance devices
in southern Indiana. These devices replace traditional flaggers with a changeable message board and stop/slow paddles.
This type of attenuator has been used by the Missouri Department of Transportation (MoDOT), which conducted a similar study in 2017. Since the conclusion of its research, MoDOT has around 100 of these devices in its fleet.
The goal of automated flagging is to increase flagger safety by removing workers from the immediate vicinity of traffic, relocating them inside a vehicle, where the system is operated during maintenance operations.
