This one hour webinar will include two presenters and two presentations. The first will be presented by Skylar Knickerbocker and the second by Neal Hawkins.

The first presentation will discuss research in Iowa on the use of temporary rumble strips in work zones. Temporary rumble strips can be an effective method of notifying distracted drivers of an upcoming work zone on two lane roadways with flagging operations. This research looked at the impacts temporary rumble strips have on driver behavior for a limited number of sites in Iowa.

The second presentation will discuss smart arrow boards and other connected temporary traffic control devices (cTTCD). Smart arrow boards and cTTCD have the ability to communicate their location as well as which lane is being closed and then provide that to the public in real-time with the intention of improving driver awareness of work zones. The Iowa DOT will begin requiring smart arrow boards on selected roadways in 2021, which required a multi-year process to understand how to communicate and work with these new types of devices. This session will focus on using connected field devices to generate accurate real-time work zone information including position of road/lane closures. This includes discussing what connected temporary traffic control devices are, what they can do, how they can be used, and the challenges of using these devices within an agency.
