Ontario construction assistant
Book 7 traffic control plans, built on the map
Tap Ontario road segments on a map, describe your work zone, and generate a Book 7–compliant traffic control layout with sign placement, buffers, and exportable PDF — powered by province-wide ORN road data and an on-device compliance engine.
- No cloud AI required for TCP generation
- ~583k ORN road segments province-wide
- Binary compliance — blocked if non-compliant
- PDF export with map snapshot

What's live today
On-device Book 7 traffic control
The compliance engine runs entirely on your device. Layout types, sign placement, buffer distances, and taper geometry are computed against OTM Book 7 tables — not approximated by a generic AI.
ORN road lock
Jobsites snap to the Ontario Road Network — real posted speeds, lane counts, and centerline geometry for sign placement.
Regulatory sign placement
TC-001, TC-002, TC-021, TC-022, taper signs, and more — placed at Book 7 table distances from the work face on both approach legs.
PDF export
Export your compliant layout as a PDF with an embedded map snapshot — ready for supervisor review and field use.
How it works
From map tap to compliant layout
Five steps. No uploaded site plans required — your jobsite is defined directly on Ontario road geometry.
Project setup
Create or select a project for your jobsite.
Chain capture
Tap ORN road segments on the map to define your work zone along the centerline.
Work description
Complete the Book 7 form — speed, closure type, traffic control method, and work details.
Generate
The on-device engine computes layout, signs, and buffers. Non-compliant plans are blocked.
Result + export
Interactive map with supervisor overlay. Export to PDF.
More capabilities on the horizon
These features are planned for future releases. They are not part of the current download and require cloud AI infrastructure that is not enabled in today's engine-only builds.
