What We Do

Our work covers capital infrastructure and development projects, including roads, highways, intersections, traffic signals, pavement markings, traffic signs, street lighting, parking lots and active transportation infrastructure.

We Work With:

Federal, provincial and municipal road authorities.

Engineering, planning and architectural consulting firms.

Land developers and property owners.

Law enforcement agencies and Legal firms requiring expert input for motor vehicle collisions / accidents.

Private citizens, resident associations and neighbourhood communities seeking safer streets and traffic calming solutions.

Institutions, schools, campuses and retail / commercial businesses.

Our Approach

1. Define the problem and objectives (safety, capacity, access, compliance).

2. Collect and analyze data (traffic counts, speed studies, travel time, delays, collisions).

3. Model and evaluate alternatives through planning, simulation and technical analysis.

4. Develop practical, staged recommendations suitable for implementation and budgeting.

5. Support implementation and monitoring, including signal timing, signage, pavement markings and before‑and‑after studies.
