21.4 Coordinated Use of Connected Vehicle Technologies for Worker Presence

The American Association of State Highway and Transportation Officials (AASHTO) Committee on Maintenance conducted a webinar on March 10, 2026, that showcased several examples of CV (or connected device) technologies for work zone and worker presence reporting.

  • Kentucky Transportation Cabinet (KTC). HERE traffic reports of general traffic speeds are compared to slow moving KTC maintenance vehicles through data received by GeoTab. GeoTab tracks in real time maintenance vehicle location. KTC systems can then identify when a KTC vehicle is in the work zone, and reports on 511 are updated to indicate workers present.
  • Haul Hub Technologies. Haul Hub Technologies presented how equipment manufacturers (e.g., Caterpillar, John Deere) telematics systems send data to the Original Equipment Manufacturer (OEM) and the data can be accessed. Haul Hub Technologies shared their approach to ingesting this OEM data and providing it to State DOTs. One use of this is to process the DOT equipment location and speed data to determine when DOT maintenance vehicles are at work zone sites.  This can enable an update to Work Zone Data Exchange (WZDx) messages to populate the worker presence field.
  • iCones and other devices. Another example presented was iCones. This and other similar vendors offer equipment that can report when cones or other control devices are deployed as another indicator of workers present

NWP members are advancing the concept of sharing event reports to the SDX to reach third party information dissemination and navigation systems (e.g., Google Maps). Road closure reports on Interstates were identified as the highest event report to focus on initially, however work zones with properly described worker presence was also of high interest. Several State DOTs (as shared in a recent AASHTO Committee on Maintenance webinar) have real-world practical examples of the use of CV data (today) to populate worker presence reports. The technologies and systems used in these may already be operational in NWP states today.

Deliverables

  • In progress.
