What is OTM Book 7? The Ontario Traffic Manual, Book 7 (Temporary Conditions) is the provincial standard for setting up safe work zones on Ontario roads. It defines the layouts, signs, taper lengths, and spacing required whenever a lane is closed or work happens near traffic. Every plan TCTWZ builds follows it.
The old way is slow
Building a basic plan by hand takes a trained person 20 to 30 minutes. Flip, match, look up, redraw, double-check. Every single time. Here is the same job, two ways.
How it works
Road type, posted speed, work duration, and closure type. Plain questions, no manual lookups.
The right Book 7 layout with taper length, buffer area, sign spacing, and sight distance, all calculated for your site.
Print it for records, email it to the crew, or open it on your phone or tablet right at the work zone.
What you get
Every layout and dimension follows the Ontario Traffic Manual, Book 7, April 2022. No guesswork.
Runs in any browser and installs to your phone or tablet. No printer needed out on the highway.
See the actual Book 7 layout for your scenario, not just a code. Save it, email it, or print it with the plan.
When the standard layout does not fit, mark it modified and adjust. A grid sketch sheet is included for on-site changes.
Built by a team of safety professionals with more than 20 years in Ontario construction.
We built TCTWZ because we were tired of building these plans by hand too. It does the lookups and the math, so you can get back to the work.
