Traffic impact assessments in British Columbia

A traffic impact assessment shows a municipality how a development will affect the surrounding road network and what, if anything, is needed to accommodate it. We prepare TIAs to each municipality's terms of reference and, where a provincial highway is involved, BC Ministry of Transportation and Transit requirements.

Our TIA stages

Pre-Application Traffic Note

A concise pre-application traffic analysis that gives you and your planning consultant a clear picture of site access, trip generation and likely municipal requirements before full design.

The full fee of this Traffic Note credits toward your Traffic Impact Assessment if you proceed.

TIA Scoping Memo

A structured scoping memo covering intersection counts, study area, analysis horizons and deliverables, so you can issue an RFP or brief a consultant knowing what the municipality will ask for.

Traffic Impact Assessment

A complete Traffic Impact Assessment prepared to the municipality's terms of reference and, where a provincial highway is involved, BC Ministry of Transportation and Transit requirements. Prepared and sealed by a Professional Engineer registered with Engineers and Geoscientists BC.

Frequently asked questions

What is a Traffic Impact Assessment (TIA)?
A Traffic Impact Assessment (TIA) is an engineering study that evaluates how a proposed development will affect the surrounding road network. A TIA documents existing traffic conditions, forecasts future traffic, identifies impacts and recommends mitigation measures. It is prepared and sealed by a Professional Engineer registered with Engineers and Geoscientists BC.
When do I need a TIA for my development?
A TIA may be requested for rezoning, development permit and subdivision applications, particularly where a project generates significant vehicle trips, changes access, or may affect nearby intersections or a provincial highway. Requirements vary by municipality; use our Traffic Study Checker or contact us with your site details.
What is the Pre-Application Traffic Note credit?
When you commission a JADE Pre-Application Traffic Note, the full fee you paid credits toward your Traffic Impact Assessment if you proceed. Site data, trip generation calculations and intersection assessments from your Traffic Note can be used in the full assessment, so you do not pay twice for the same groundwork.
Do you handle municipal coordination and resubmissions?
Yes. We can coordinate technical questions with the reviewing authority and support responses and resubmissions within the agreed scope.
