Every sign. Every guardrail. One survey drive.
RoadSense finds road signs and guardrails in the survey video, places them on the road, and puts each one in front of a reviewer. Confirmed signs are rated to TMH 19 and land in an asset register you can export.
Knowing what stands beside the road is part of looking after it
A road authority needs to know which signs and guardrails it owns, where they are, what condition they are in and which to fix first. Walk-through inspections are slow and hard to repeat. A survey you cannot defend is a survey you will do twice.
Without RoadSense
With RoadSense
One drive, every view
The survey vehicle records front, side and rear cameras together with the profiler and the GNSS track. The front and rear cameras feed the pavement views and the bird's-eye scan. The side camera looks across the verge, where signs, chevrons and guardrails stand.
Side camera
Reads the roadside: sign faces, chevron boards and guardrail runs in full view beside the vehicle.
Front camera
The view down the road for context, review and the drive record.
Bird's-eye scan
The same drive stitched into a top-down map of the surface for patches, potholes and cracking.
One position
All views share one GPS track and chainage, so a sign, a crack and a profile reading can be found at the same place.
From video to a reviewed, rated register
1. Detect
Sign faces are found and read against the SARTSM catalogue. Guardrails are segmented and checked by a verifier. Only detections at or above 0.8 detector confidence go forward, and that confidence is shown on every box.
2. Track and place
Each sign is followed back to its first far sighting so it becomes one record, not dozens of frames. Its position is estimated from the views, and the camera point is kept beside it. Guardrails are tracked from first to last view.
3. Review
RoadSense Sign Review puts each candidate in front of a person with the full frame, a crop and the SARTSM reference face. Accept, reclassify or remove. Nothing is published on a model's word alone.
4. Rate
For each confirmed sign the assessor records degree, extent and relevancy per defect, following TMH 19. Make Safe items rank first. Defects TMH 19 does not cover are marked as RoadSense extensions.
5. Register
Confirmed signs and guardrail runs go into an asset register with code, name, side and chainage. Export the register as CSV and the assets as GeoJSON.
6. Plan, then survey again
The register sets the next inspection and the next survey drive. Each new drive updates the same records.
What each record carries
| Field | Signs | Guardrails |
|---|---|---|
| Identity | One record per physical sign, with all its views | One record per guardrail run |
| Code and name | SARTSM code and name | Guardrail |
| Location | Side, chainage, estimated position and camera position | Side, start and end chainage as observed |
| Evidence | Best frame, crop and every supporting view | First, continuing and last observed frames |
| Review | Accepted, reclassified or removed, with who and when | Published or held for review |
| Condition | TMH 19 degree, extent, relevancy; urgency; Make Safe | Not rated yet: a guardrail condition scale is still to come |
| Export | signs.csv with defects.csv | assets.geojson |
