About the research

This grant will support the establishment of an Iowa Department of Transportation (DOT) WZDx-compliant data feed. The feed will be integrated into the statewide Advanced Traffic Management System (ATMS) and populated with the Institute for Transportation’s new and improved Work Zone Data Initiative (WZDI), which uses data from smart arrow boards statewide to automate how work zone time and location information is updated.

The Iowa DOT relies on their 511 website to communicate with the public. Data typically follows the Traffic Management Data Dictionary (TMDD) standard, which lacks the details necessary for work zones, thus leading to the need for WZDx.The information within most DOT 511 websites is often an inaccurate representation of the work zone in the field due to several factors, including the required manual input of data from field staff and TMC operators.
