Ensure your development gains approval with a comprehensive, data-driven Traffic Impact Assessment.
At Arterials, we provide professional Traffic Impact Studies (TIA/TIS) that meet municipal requirements and help developers, municipalities, and consultants make informed decisions about transportation impacts. Whether you are developing a residential community, commercial plaza, mixed-use project, or industrial facility, our team delivers reports and recommendations that satisfy regulators and protect your investment.
What is a Traffic Impact Assessment?
A Traffic Impact Assessment evaluates how a proposed development will affect the surrounding road network. Most planning authorities require a TIA to ensure that new trips generated by a project can be safely and efficiently accommodated without causing unacceptable congestion or safety issues.
Our studies are built to international standards (ITE, TRICS, Austroads, regional municipal guidelines) and tailored to local approval processes.
What Our TIA Service Includes
When you commission a TIA from Arterials, you receive a full-service analysis that goes beyond traffic counts. Our scope typically includes:
1. Trip Generation & Distribution
- Estimation of site-generated trips using ITE Trip Generation or locally calibrated data.
- Adjustments for mode split, internal capture, and pass-by trips where applicable.
- Peak hour trip forecasts tailored to your development type.
2. Traffic Assignment & Network Integration
- Trip distribution models applied to the local network.
- Assignment of trips in Synchro / VISUM / VISSIM for accurate simulation.
- Integration with existing traffic volumes and future background growth.
3. Capacity & LOS Analysis
- Intersection analysis using Synchro/Highway Capacity Manual (HCM) methodology.
- Level of Service (LOS), delays, and queue length calculations for AM/PM peaks.
- Corridor or roundabout analysis where required.
4. Site Access & Design Review
- Driveway location and spacing checks.
- Sight distance evaluation for safe access.
- Parking and loading supply assessment against municipal codes.
- Swept Path Analysis (AutoTURN) to confirm access for service vehicles, delivery trucks, and emergency vehicles.
5. Traffic Management & Safety
- Identification of potential safety issues (conflicts, pedestrian exposure, vulnerable road users).
- Recommendations for traffic signals, turning lanes, pedestrian crossings, and signage.
- Temporary construction traffic management plans where required.
6. Recommendations & Mitigation
- Clear, practical mitigation measures to address impacts, such as:
- Signal timing adjustments
- Road widening or turn lanes
- Traffic calming measures
- Parking management strategies
- Always cost-conscious and proportional to the development.
Deliverables You Receive
By the end of the study, you receive a comprehensive report and supporting files that can be submitted directly to planning authorities:
- PDF Traffic Impact Study Report (ready for submission)
- Technical Appendices including data tables, trip gen worksheets, and Synchro outputs
- Figures and Drawings:
- Existing and future traffic volumes
- Site access plans
- AutoTURN swept path diagrams
- Recommendations Summary tailored for approval conditions
- Editable files (if required): Synchro models, CAD drawings, spreadsheets
Our deliverables are designed to stand up to municipal scrutiny and facilitate smooth project approval.
Our Process
We follow a structured, transparent approach so you always know what to expect:
- Scoping & Proposal – We review your project plans and municipal requirements, then confirm study scope and timelines.
- Data Collection – Assist in gathering required traffic counts, site plans, and any background data.
- Analysis & Modelling – Conduct trip generation, assignment, and LOS calculations in Synchro/other tools.
- Site Review – Evaluate access, parking, and swept paths.
- Draft Report – Share preliminary findings with client for feedback.
- Final Submission – Deliver a polished, submission-ready report package.
- Municipal Support – We provide responses to authority comments and revisions if required.
Why Choose Arterials?
