LaneWarden Pace
Variable speed limit sign with speed feedback
In every kit
Overview
A trailer-mounted regulatory speed limit sign with a YOUR SPEED display. It shows the work zone limit when workers are present and the normal limit when they are not, inside the envelope the agency approved.
A work zone speed limit only earns respect if it applies when drivers see it. Pace shows the reduced limit while a crew is present and returns to the normal limit when the work area is empty.
Speed feedback gives drivers their own measured speed, and the readings go into Command as another detection point at the start of the reduced-speed zone.
What it does
Pace at work
YOUR SPEED feedback
Displays each approaching driver's measured speed below the limit.
Changes inside the approved envelope
Remote changes for ice or incidents are limited to the speeds the agency approved, and every change is logged with who made it and why.
See the work zone limit and YOUR SPEED readings, with the same rules the system runs.

Portable changeable message sign that measures the traffic it warns
A full-matrix portable message sign with a Doppler radar facing oncoming traffic. It posts queue, delay and hazard messages from an approved library, and falls back to a safe message on its own if its data stops.

LaneWarden Sentinel
Worker-protection trailer that alarms before a vehicle reaches the crew
A mast trailer at the upstream end of the taper or flagger station. Tracking radar and AI cameras watch the approach; when a vehicle is on course for the work space or cannot stop for the flagger, it sounds a 110 dB siren and strobes, texts the foreman and saves the video.
