How do you assess traffic and parking impacts for a major community sports facility?
Large community sporting facilities can generate significant traffic and parking demands during short peak periods. A detailed Traffic Impact Assessment helps determine whether the surrounding road network and parking supply can safely and efficiently accommodate those demands while balancing the expectations of local residents, councils and facility users.
Overview

Quantum Traffic was engaged by Bayside City Council to undertake a detailed Traffic Impact Assessment associated with the proposed Bayside Netball Centre development in Sandringham, Victoria.
The proposed facility represented a significant investment in local sporting infrastructure, with Stage 1 and Stage 2 works supported by more than $28 million in combined Council and Federal Government funding. The proposal sought to transform the existing golf driving range site on Wangarra Road into a major regional netball facility comprising:
- up to 15 outdoor netball courts
- 3 indoor courts
- approximately 280 on-site car parking spaces
Given the scale of the proposed development and the change in land use intensity compared to the existing golf driving range, there was considerable community interest regarding the potential impacts on local traffic conditions, parking demand and neighbourhood amenity.
Quantum Traffic’s Role
Quantum Traffic was engaged to provide specialist traffic engineering advice to support the planning approval process and assess the operational impacts associated with the proposed development.
Our scope included:
- Traffic Impact Assessment preparation
- Existing traffic surveys and data collection
- Car parking demand assessment
- SIDRA intersection modelling
- Traffic generation forecasting
- Peak event operation analysis
- Parking supply review
- Access and circulation assessment
- Community consultation support
- Strategic mitigation advice
The assessment considered both average daily conditions and peak competition/event periods to ensure the facility could operate safely and efficiently during its highest demand scenarios.
Understanding the Traffic and Parking Challenge
A key challenge associated with the project was the significant increase in visitation expected compared to the existing golf driving range use.
Unlike traditional commercial developments that often generate more evenly distributed traffic throughout the day, sporting facilities such as netball centres typically experience concentrated traffic peaks associated with:
- weekend competitions
- simultaneous match scheduling
- school and junior sport periods
- evening training sessions
- spectator activity
This creates unique traffic engineering considerations relating to:
- concentrated arrival and departure patterns
- short-duration parking demand peaks
- intersection queueing assessments/management
- pedestrian safety
- parent drop-off/pick-up activity
- interaction with surrounding residential streets
Quantum Traffic undertook detailed assessments to determine the likely peak parking accumulation and traffic generation associated with the ultimate facility yield.
SIDRA Intersection Modelling
As part of the assessment, SIDRA intersection modelling was undertaken to assess the operational performance of surrounding intersections under future traffic conditions.
The modelling assessed:
- existing traffic conditions
- future background traffic growth
- additional netball centre traffic demands
- intersection capacity
- delays and queue lengths
- vehicle circulation patterns during peak periods
This analysis helped identify whether the surrounding road network could accommodate the additional traffic generated by the facility and whether any mitigation measures or upgrades were required.
The assessment considered not only the volume of traffic generated, but also how the arrival and departure characteristics of organised sporting events influence traffic flow and parking behaviour.
Balancing Community Concerns

Projects of this nature often attract strong community interest, particularly where existing neighbourhoods are undergoing change.
Local residents understandably raised concerns regarding:
- increased traffic volumes
- parking overflow into surrounding streets
- congestion during peak competition periods
- impacts on neighbourhood character and amenity
- pedestrian safety
Quantum Traffic’s role extended beyond technical modelling and engineering analysis. We also participated in community consultation sessions conducted by Bayside City Council to help explain the findings of the assessment and respond directly to resident concerns.
This process allowed the project team to:
- communicate technical findings transparently
- explain how traffic impacts were assessed
- identify additional areas requiring investigation
- better understand local behavioural patterns and concerns
- refine aspects of the proposed operation and mitigation strategy
Importantly, the consultation process reinforced that traffic engineering is not simply about accommodating vehicles. It is about helping deliver balanced outcomes that support both community infrastructure and neighbourhood liveability.
Outcomes and Benefits
The assessment demonstrated that the proposed netball centre could be supported from a traffic engineering and parking perspective, subject to appropriate planning and operational considerations.
Key outcomes included:
- establishing an appropriate on-site parking provision
- understanding likely peak traffic conditions
- assessing surrounding intersection operation
- identifying traffic management considerations
- supporting the broader planning approval process
- assisting Council in responding to community concerns with evidence-based analysis
The work formed an important component of the planning and consultation process associated with delivering a major new community sporting facility for the Bayside area.
Why This Project Matters
The Bayside Netball Centre project demonstrates the importance of detailed traffic engineering input for large-scale community infrastructure projects.
Sporting facilities present unique operational challenges due to highly concentrated peak demands and strong community interest regarding parking and traffic impacts.
This project also highlights the value of combining:
- robust technical analysis
- practical traffic engineering solutions
- transparent stakeholder engagement
- evidence-based communication
At Quantum Traffic, we understand that successful outcomes require more than modelling software and technical reports. They require practical solutions that balance infrastructure delivery, operational efficiency and community expectations.
Frequently Asked Questions (FAQ)
Why are traffic assessments important for sporting facilities?
Sporting facilities can generate intense short-duration traffic peaks associated with matches, training sessions and events. Traffic assessments help ensure the surrounding road network and parking supply can safely accommodate those demands.
What is SIDRA modelling?
SIDRA is a traffic modelling software package used to assess intersection operation, queue lengths, delays and network performance under existing and future traffic conditions.
Why was parking a key issue for this project?
The proposed netball centre represented a substantial increase in activity compared to the existing golf driving range, creating significantly higher parking demand during peak sporting periods.
How are community concerns addressed during these projects?
Traffic engineers often work alongside councils and project teams during consultation processes to explain technical findings, respond to concerns and identify practical mitigation measures.
Can Quantum Traffic assist with community and recreation projects?
Yes. Quantum Traffic regularly undertakes Traffic Impact Assessments and parking assessments for sporting facilities, schools, community infrastructure and major recreational developments across Australia.
