One hazard. Every job on the road.

Wherever a crew works next to live traffic, the risk is the same: a vehicle enters the work zone before anyone on foot sees it coming. RoadDefender watches the approach and puts a warning on every worker's wrist — in time to move. The equipment changes and the uniform changes, but the hazard doesn't.

Where RoadDefender works

Here's what that looks like across the jobs that put people on foot in live traffic — the exposure, the warning that answers it, and who funds it.

Paving

Paving & resurfacing

The hazard
Crews on foot for hours behind moving equipment, feet from a live lane.
The warning
Warns the whole paving train on the wrist as traffic bears down — everyone at once, in time to move.
Who pays
A DOT work-zone safety pay-item, modeled on the FDOT reimbursement path.
Milling

Milling & cold planing

The hazard
Crews walk the cut alongside the mill all shift, feet from an open lane, with machine noise burying the sound of an approaching vehicle.
The warning
Warns the mill crew and the haul-truck spotters on the wrist — through the noise, before the vehicle reaches them.
Who pays
The same DOT work-zone safety pay-item as paving — it rides on the resurfacing contract.
Structures

Bridge deck & structure repair

The hazard
No shoulder, no escape path — the crew works a narrow deck with a live lane on one side and a rail on the other.
The warning
Warns everyone on the deck at once — in time to step behind the barrier.
Who pays
Bridge and structures contracts, as a work-zone worker-protection line item.
Safety hardware

Guardrail, barrier & attenuator work

The hazard
Crews stand at the edge line to place the very device that would have protected them.
The warning
Puts the warning on the wrist before the barrier exists to stop anything.
Who pays
Safety-hardware contracts, on the same DOT work-zone pay-item path.
Traffic control

Traffic control setup & takedown

The hazard
Setting and pulling cones puts workers in the live lane with no protection at all — before the zone exists, and after it's gone.
The warning
Deploys first and comes down last — the crew is covered for the two most exposed minutes of the job.
Who pays
MOT line items on the prime contract.
Maintenance

Maintenance crews

The hazard
Short setups, no hard barrier, beside traffic that never slows.
The warning
Deploys in minutes and warns each worker on the wrist — no fixed install required.
Who pays
Fits agency force-account and maintenance budgets.
The procurement path First PS&E Nov 2026 · 23 CFR 630 Subpart K

Worker protection is moving onto the project record. RoadDefender is built to be specified and funded.

Subpart K raises what federal projects are expected to document about work-zone exposure and the measures taken to control it. RoadDefender is built to fit that path three ways:

  • Specifiable capability Deploys as a named worker-protection measure your agency can write into the spec — describing what was in place, and when.
  • Reimbursable pay-item Funded as a DOT work-zone safety line item — not paid out of your own margin.
  • Event record — in development Time-stamped alert and acknowledgment records for compliance review are in active development, not yet a shipped capability.
