Overview

The Dairy Road Precinct in Fyshwick, ACT is a visionary mixed-use development set to transform the area into a dynamic hub of residential, commercial, and recreational activity. To support the planning and approval process, Quantum Traffic was engaged to assess the future development scheme, focusing on the traffic impacts to the surrounding road network.

Using detailed Aimsun traffic modelling, Quantum Traffic provided critical insights into future traffic conditions, network performance, and infrastructure requirements, ensuring the development integrates seamlessly with the broader transport system.

Services

To assess and mitigate the potential impacts of the Dairy Road development, Quantum Traffic delivered:

Traffic Impact Assessment (TIA) – Evaluating development-generated traffic volumes, access arrangements, and road network performance.
Aimsun Traffic Modelling – Conducting detailed microsimulation modelling to analyse traffic flow, congestion points, and future operational performance under various development scenarios.
Intersection Performance Analysis – Assessing the capacity and efficiency of key intersections, identifying potential upgrades to accommodate increased demand.
Infrastructure & Mitigation Recommendations – Proposing road network improvements, intersection upgrades, and traffic management strategies to support the precinct’s growth.

Outcomes/Benefits

One of the primary challenges of the Dairy Road Precinct assessment was forecasting future traffic conditions in an evolving urban environment. Additionally, the interaction between the development and key arterial roads required careful analysis to manage congestion issues.

Advanced Aimsun Traffic Modelling – Quantum Traffic used high-resolution simulations to predict traffic flow under various future growth scenarios, ensuring robust planning outcomes.
Strategic Intersection Analysis & Planning – Identified potential bottlenecks and capacity constraints, recommending upgrades and signal timing adjustments to maintain efficient operations.
Balanced Growth & Network Efficiency – Proposed staged infrastructure improvements to align with development milestones, ensuring road network performance is maintained over time.

Challenges/Solutions

A key challenge was ensuring the efficiency of the entry and exit phases of the event, where large volumes of vehicles and pedestrians arrived and departed within short timeframes. Poorly managed access could lead to excessive queuing, congestion, and delays, impacting local road networks and festival operations.

Entry Phase Analysis – Quantum Traffic reviewed arrival patterns, access points, and capacity constraints to ensure smooth vehicle entry. Recommendations included staggered arrival times, additional entry lanes, and improved wayfinding signage to reduce queuing and bottlenecks.
Exit Phase Planning – The mass departure of festivalgoers required effective dispersal strategies to prevent congestion. Quantum Traffic assessed capacity at the site egress point and suggested active management of exit movement to reduce queueing.
Queue Management & Contingency Planning – Identified potential overflow areas, temporary traffic controls, and real-time management strategies to prevent excessive queuing and ensure emergency access remained clear.
