Measuring Safety Performance in Your Own Traffic Control Company

National work zone statistics describe a country, not your operation. Which metrics actually tell you whether your company is getting safer, how to collect them without a research budget, and how to present them to an agency or an underwriter.

Work Zone Intrusions: Prevention, Response, and the Data Nobody Collects

An intrusion is a vehicle entering the work space. Most of them hurt nobody and appear in no federal dataset — which is exactly why they are the most useful safety signal a traffic control company can capture, and the one almost nobody does.

Work Zone Speed Management and Automated Enforcement

Speeding is a factor in roughly a third of fatal work zone crashes. What speed management actually consists of beyond posting a reduced limit, how automated work zone enforcement programs are structured, and what any of it changes for the contractor setting up the zone.
