Traffic Impact Studies in Brampton

Understanding the Transportation Requirements for Your Development

A Traffic Impact Study (TIS) assesses how a proposed development will affect the surrounding road network, intersections, site access and transportation operations. In Brampton, the study helps determine whether existing and planned infrastructure can accommodate anticipated traffic demand and identifies improvements that may be necessary to support a development.

The City’s Traffic Impact and Parking Study Terms of Reference outline the technical requirements for new and infill developments, including dedicated assessments for school sites and places of worship. The scope of work is determined by the City of Brampton’s Traffic Planning staff, with coordination from the Region of Peel where required.

What Does the Study Process Involve?

1. Defining the Scope and Reviewing Existing Conditions

The process begins by confirming the required study type, analysis area and technical scope with City staff. The consultant documents the proposed development, including land uses, floor area, residential units, operating hours, anticipated occupancy and project phasing. Existing roads, intersections, traffic controls, transit stops, cycling facilities and nearby developments are also reviewed.

2. Collecting Traffic Data and Forecasting Demand

Traffic counts and turning movements are collected or obtained from the City to establish existing conditions. Brampton’s guidelines identify morning, afternoon and off-peak periods as minimum analysis periods, with Saturday assessments potentially required for commercial developments. Future traffic forecasts consider background growth, surrounding developments and trips generated by the proposed site.

Forecasts must assess appropriate future horizons, typically five, ten and twenty years depending on the development’s build-out and the City’s direction. Trip generation assumptions may be supported by comparable Brampton developments or industry-standard trip-generation rates.

3. Evaluating Traffic Operations and Site Access

The consultant assesses intersection capacity, volume-to-capacity ratios, levels of service, vehicle queues and the performance of proposed site accesses. The analysis considers existing conditions and future scenarios, both with and without recommended mitigation measures.

Particular attention is given to access spacing, turning movements, queue storage, sightlines and potential conflicts involving pedestrians, cyclists, heavy vehicles and other road users.

4. Identifying Mitigation and Infrastructure Improvements

Where operational or safety issues are identified, the study recommends appropriate solutions. These may include turning lanes, additional road capacity, signalization, access modifications, intersection improvements or revised site circulation. A functional design illustrating proposed access configurations or intersection geometry may also be required.

5. Preparing the Technical Report

The final report documents the study methodology, traffic forecasts, analysis results, improvement alternatives and recommendations. Supporting material may include traffic counts, signal timing information, modelling outputs, technical appendices and access or intersection drawings. Reports must be prepared by a qualified transportation consultant and signed, dated and stamped by a qualified transportation professional.

What Makes Brampton’s Requirements Distinctive?

Detailed traffic simulation: The linked guidelines require queueing assessments supported by microsimulation, rather than relying solely on conventional intersection-capacity modelling. They specify a minimum of five simulation runs, with defined run and seeding periods, to help identify issues such as queue spillback, forced lane changes and uneven lane utilization.

Long-term traffic forecasting: Assessments consider multiple future horizons, including five-, ten- and twenty-year scenarios where appropriate. This helps identify infrastructure constraints that may emerge as surrounding areas develop.

Field-verified access safety: Proposed accesses must be evaluated for stopping and turning sight distance using field measurements and applicable design standards. The safety review also considers pedestrian and cyclist conflicts, merging and weaving, heavy-vehicle movements, corner clearances and relevant collision history.

Specialized school traffic assessments: Proposed school sites require a dedicated assessment addressing opening dates, enrollment, school hours, catchment areas, busing, bus routes, pedestrian routes and potential crosswalk locations. The objective is to identify necessary infrastructure and operational improvements before the school opens.

Event-based parking and traffic studies for places of worship: Brampton requires a parking and traffic impact study for new or redeveloped places of worship. The assessment considers normal operations as well as major events, evaluates surrounding road-network performance and determines appropriate on-site parking demand using surveys of comparable, City-approved sites.

Plan Ahead for Development Approval

Early consultation with Brampton Traffic Planning staff helps establish the appropriate study scope, identify potential access and capacity constraints, and determine whether additional reviews or coordination with the Region of Peel are necessary. Integrating these requirements into the initial site design can help reduce redesign, improve transportation safety and support a more efficient development application review.
