Compare permitted work with road activity.
Use lane movement and time records to check work hours, closure size, and when traffic returned. A continuous record can show more than one site visit or photo.
What the record shows about a closure.
Check work hours
When the lane emptied and when it filled again, against the hours on the permit.
Check closure size
Which lanes actually stopped carrying traffic, compared with the ones on the paperwork.
Check when traffic returned
How long past the end of the window the lane stayed shut, in minutes.
Find the blocked crosswalk
When crossings drop to zero on one side and jump on the other, people are walking around something.
The record measures the road.
A permit check uses a place and time window. The structured movement record describes lane use and traffic flow. It does not name a crew member, read a plate, or decide whether an agency should take action.
A pilot starts with one road question, a selected location, and a test plan.
