Overview

The East Gungahlin High School, which commenced operations in 2024, is a key addition to the rapidly growing Gungahlin region, requiring a comprehensive traffic and transport assessment to support its successful integration into the surrounding network. Quantum Traffic was engaged to develop a large-scale Aimsun traffic model, assessing the impacts of school-generated traffic and ensuring that the surrounding road network could efficiently accommodate anticipated volumes.

In addition to road network and intersection planning, Quantum Traffic undertook a detailed pedestrian movement analysis, resulting in the provision of a high-standard shared path connecting the school to the existing light rail services along Flemington Road, promoting active and sustainable transport options for students and staff.

Services

To support the successful planning and operation of the school, Quantum Traffic delivered:

Aimsun Traffic Modelling – Developing a detailed network simulation to assess school-related traffic impacts and guide road network planning.
Road Network & Intersection Development – Developing and refining key access roads, intersections, and traffic controls to efficiently handle anticipated traffic volumes.
Pedestrian Movement & Safety Analysis – Evaluating student travel patterns and recommending safe, high-quality pedestrian connections to key transport links.
Public & Active Transport Integration – Ensuring seamless connectivity to the light rail network on Flemington Road through enhanced pedestrian and cycling infrastructure.

Outcomes/Benefits

Optimised road network design, ensuring efficient vehicle flow and school access.
Improved pedestrian connectivity, with a high-standard shared path linking to light rail services.
Future-proofed transport planning, accommodating long-term growth in the Gungahlin region.
Enhanced traffic safety, ensuring safe and efficient school drop-off and pick-up operations.

Challenges/Solutions

The key challenge in this project was ensuring that the surrounding road network and intersections could effectively handle peak school traffic, while also prioritising safe and efficient pedestrian movements.

Large-Scale Aimsun Modelling – Developed a detailed microsimulation model to accurately forecast traffic conditions, congestion points, and network performance, ensuring effective transport planning.
Strategic Intersection & Access Planning – Developed road and intersection improvements, optimising entry/exit points, traffic signals, and parking layouts for smooth operations.
Enhanced Pedestrian & Active Transport Infrastructure – Identified the need for a dedicated shared path to improve student safety and encourage sustainable transport options, facilitating a strong connection to Flemington Road’s light rail services.
