Description

work zone information

Summary of maintenance and construction work zone activities affecting the 
road network including the nature of the maintenance or construction activity, 
location, impact to the roadway, expected time(s) and duration of impact, 
anticipated delays, alternate routes, and suggested speed limits.  This 
information may be augmented with images that provide a visual indication of 
current work zone status and traffic impacts.

work zone status

Current work zone status including current location (and future locations for 
moving work zones), impact to the roadway, required lane shifts, expected 
time(s) and duration of impact, anticipated delays, alternate routes, and 
suggested speed limits.

work zone warning notification

Notification of a work zone emergency or safety issue.  This flow identifies that 
a work zone emergency or safety issue has occurred so that warnings may be 
generated by more than one system in the work zone.

work zone warning status

Status of a work zone safety monitoring and warning devices.  This flow 
documents system activations and includes additional supporting information 
(e.g., an image) that allows verification of the alarm.
