Field Escort · Road-safety feed

Warn drivers before they meet slow equipment

A tractor mowing a ditch at 5 mph on a 55 mph rural highway is a crash risk: drivers come over a rise and it is simply there. Field Escort turns the positions that farm equipment, maintenance mowers and snowplows already report into a public road-safety feed, so navigation apps, traveller information and roadside message signs can warn drivers before they see it.

The live map: every marker is a slow-moving machine on a public road, refreshed every 60 seconds. (Replay of 13 Oct 2026, 1:33 PM: 39 machines on the road, one sign advised.)

What it does, every minute

Public roads only

Positions are checked against the state road network and anything not on a public road is discarded. Equipment working a field, sitting in a yard or at a home is never published. That privacy gate is what owners agree to.

Where it is now

Equipment reports a position and then goes quiet for a while. Field Escort advances each machine along the actual road from its last report, and draws the stretch behind it, the road a closing driver is on, as the warning zone.

Standard feeds

Published as a WZDx 4.2 work-zone feed and a Waze CIFS feed, the formats mapping providers and traveller-information systems already ingest.

Which sign, and what it says

Recommends which message signs upstream of a machine should warn, with copy that fits a three-line board: SLOW VEHICLE / 2 MI AHEAD / 6 MPH, or SNOW PLOW in winter conditions. A recommendation, not a command: the traffic system decides.

See it

Click a machine: road, direction, speed, side of the road, a head-on warning when it works against traffic, and the nearest camera. The dashed orange line ties it to the sign advised for it.
