INDOT’s Use of Archived Work Zone Data
This fact sheet focuses on how the Indiana Department of Transportation (INDOT) used archived work zone technology application data to benefit the agency and traveling public.
Background
The Work Zone Safety and Mobility Rule1 requires state agencies to collect operational data to better manage resulting safety and mobility impacts in work zones. Many technologies are available for work zone data collection and recent innovations make data collection easier and less expensive. Temporary data collection technologies can support applications like queue warning systems (QWSs), traveler information, and performance measurement. INDOT leveraged archived technology application (i.e., QWS) data from one work zone in order to modify the lane closure allowances planned for a second, adjacent work zone. This allowed the project to be completed in half the time of its scheduled duration, resulting in cost savings for both INDOT and travelers due to increased construction productivity and scheduling efficiencies.
