Built for Ontario crews who need compliant TCPs — fast
Project Helix is an Ontario construction assistant focused on one hard problem: generating traffic control plans that meet OTM Book 7 requirements, using real provincial road data and a deterministic compliance engine.
Why OTM Book 7 matters
The Ontario Traffic Manual Book 7 defines how traffic control must be set up at construction and maintenance sites — advance warning signs, tapers, buffer zones, flagger stations, and termination distances all depend on posted speed, road class, and closure type.
Getting it wrong creates safety risk, inspection failures, and costly rework. Manual drafting from tables is slow and error-prone. Project Helix automates the layout and sign placement while enforcing the standard — not approximating it.
Binary compliance — not suggestions
The engine treats Book 7 compliance as pass/fail. If a plan cannot meet the required upstream distance, sign sequence, or layout constraints for your jobsite geometry, generation is blocked — the app will not render a non-compliant layout and hope nobody notices.
When constraints can be relaxed within Book 7 rules (for example, a compliant fallback layout at reduced speed), the engine may propose alternatives — but never silently ship an out-of-spec plan.
Map-first, Ontario-specific
Jobsites are defined by tapping Ontario Road Network (ORN) segments on a map — chain capture — not by uploading PDF site plans. The app locks sign placement to authoritative road centerlines and posted speeds drawn from province-wide geodata (~583k segments).
Coverage is Ontario only. OTM Book 7 is an Ontario standard; Project Helix does not claim support for other provinces' traffic control manuals.
On-device engine, Canadian-hosted data
Traffic control plan generation runs on your device — no cloud AI required for the core Book 7 workflow. Jobsite geometry is sent to a Canadian-hosted data service for ORN lookups, placement lock, elevation, and sight-line context; see Canadian First for details.
