Traffic Analysis and Concept Design for Warooka Drive T-Intersection, Smithfield

Client

City of Playford

Location

Warooka Drive and George McCullum Road Intersection, Smithfield, South Australia

Sector

Traffic Modelling and Concept Design

Warooka Drive serves as a critical north-south local collector road in Smithfield, connecting Morialta Drive to the north and Konanda Road to the south. This local road provides a vital link between Munno Para Shopping City and the Smithfield Interchange, facilitating significant vehicle and pedestrian traffic. To ensure the intersection of Warooka Drive and George McCullum Road operates safely and efficiently, the City of Playford engaged BE Engineering Solutions (BEES) to conduct an operational assessment of existing conditions and propose alternative design solutions.

The Challenge

The Warooka Drive T-intersection faced several challenges requiring expert evaluation and design:

  • Identifying operational risks under current traffic conditions and assessing their impact on road safety and efficiency.
  • Evaluating the intersection’s performance as a key connector between high-traffic zones, including a major shopping precinct and a transport interchange.
  • Proposing and analysing alternate design options to optimise traffic flow, minimise delays, and enhance safety.
  • Ensuring proposed solutions align with local development plans and anticipated growth in traffic volumes.

Our Approach

BE Engineering Solutions adopted a systematic and data-driven approach to address the project’s objectives:

  • Conducted a thorough review of the intersection’s current conditions, analysing traffic volumes, turning movements, and pedestrian activity.
  • Identified key operational risks, including potential bottlenecks, safety concerns, and inefficiencies in traffic flow.
  • Developed a detailed SIDRA model of the intersection to simulate current performance and identify areas for improvement.
  • Proposed two alternative design options, each tailored to address specific operational risks while enhancing safety and efficiency.
  • Prepared concept sketches for the alternate designs, highlighting key features such as lane geometry, turning radii, and signage placement.
  • Assessed the performance of each design option under varying traffic conditions, including peak periods and future growth scenarios.
  • Compared key metrics, such as Level of Service (LOS), average delay, and capacity utilization, to determine the optimal solution.
  • Delivered a comprehensive report to the City of Playford, detailing the findings from the existing conditions analysis, SIDRA modelling, and proposed design options.
  • Provided recommendations to guide the next stages of design and implementation.

Outcome

The work completed by BE Engineering Solutions provided the City of Playford with actionable insights and practical design solutions for the Warooka Drive T-intersection.

Key outcomes included:

  • Clear identification of operational risks under existing conditions, enabling informed decision-making for immediate and long-term improvements.
  • Two alternative design options that balance safety, efficiency, and community needs, ensuring the intersection meets current and future traffic demands.
  • Enhanced understanding of traffic dynamics at a critical local collector road, supporting the City’s broader transport and development goals.
  • A framework for implementing cost-effective and sustainable infrastructure upgrades.
