Smart Work Zone Systems
LaneWarden designs, installs and runs the whole smart work zone for highway construction: queue warning, speed management, worker intrusion alarms and a WZDx data feed. One accountable team, from the system plan to the last report.
Illustration of a one-lane, two-way flagging operation. Flaggers release each direction in turn. When the eastbound queue reaches the Pulse radar, the Messenger sign upstream changes from WORK ZONE AHEAD to STOPPED TRAFFIC AHEAD. A Sentinel trailer watches the approach to the flagger.

What it does
Warns drivers before the queue, not at it.
Every node reports speeds every 60 seconds. When a queue forms, the sign at least half a mile before its tail posts SLOW or STOPPED TRAFFIC AHEAD. If the tail sits just past a crest, the warning moves to a sign before the hill.
Two independent layers around every crew.
Sentinel watches the approach with tracking radar and cameras and sounds the alarm when a vehicle is on course for the work space. Cone-mounted impact sensors alert crew wearables directly when a cone is struck.
The work zone limit, only when it applies.
Pace signs show the reduced limit when workers are present and the normal limit when they are not, with YOUR SPEED feedback. Changes stay inside the approved envelope and are logged.
Delay measured, reported and published.
Travel times per direction, delay alerts at 15 and 20 minutes, a WZDx 4.2 device feed every 60 seconds, and an archive of every reading, message and alarm for at least three years.
How it scales
Sized to the corridor
One per direction, per active work area
The package grows by whole kits: two work areas running at once, in both directions, means four kits. Everything that scales with work areas, including setup, relocations and removal, sits in the kit.
Devices
Worker protection
Layer 1 · Predictive
Tracking radar and AI cameras follow every vehicle on the approach and predict where it will be. The alarm sounds before a vehicle reaches the taper, not when it hits it.
Layer 2 · Boundary
Cone-mounted impact sensors from a specialist supplier sit in the taper, buffer, work-space line and equipment gate. A struck or moved cone alerts the crew's wearables directly over the supplier's own local network.
Design rules
Intrusion alarms and fail-safe sign messages run on the trailer. They never wait for a server or a cellular connection.
Radars ride on the sign and camera trailers wherever the geometry allows. Standalone detection trailers only fill gaps.
A WZDx feed every 60 seconds, delay and queue logs, intrusion reports and a three-year archive come with the system, not as extras.
Live demo
Five scenarios on a simulated corridor: a hidden queue over a crest, a work zone intrusion, ice on a grade, a device that goes silent. Scrub through the morning, acknowledge alerts, post a message and read the WZDx feed it produces.
M-4 · westbound06:59
Queue tail near MP 16.65, within 1,000 ft past the crest at MP 16.8, where drivers cannot see it. The warning is on M-4, 2.2 miles upstream and well before the hill.
