Traffic Modelling Consultant in Melbourne, Canberra and Sydney

Quantum Traffic offers specialist microsimulation modelling, for projects where detailed traffic analysis is required. We complete these traffic studies in Melbourne, Canberra and Sydney.

Microsimulation modelling undertakes analysis on a vehicle-by-vehicle basis, modelling the interaction between individual vehicles on the road network. This allows for a comprehensive analysis of road operation and traffic impacts.

THE SERVICES

Quantum Traffic utilises the Aimsun microsimulation software package that is recommended by many road authorities around Australia.


Given the detailed nature of the analysis, Microsimulation modelling generally incorporates
the following stages: 

  • Existing Conditions Data – A high level of existing conditions traffic data must support these detailed models.  Typically, this includes turning movement counts, origin-destination surveys, queue length surveys and travel time surveys.

  • Calibration & Validation of Existing Conditions Model – A critical stage of the modelling process, where the model outputs (travel time, queue lengths, etc.) are assessed against the existing conditions data to confirm the model appropriately reflects the existing road network.  This process is documented in a high-quality report, which is submitted to the road authority for approval.

  • Development / Test Scenario Modelling – The final stage of the microsimulation modelling process is to run the test/development scenario.  These typically include the traffic volumes associated with the proposed development, background growth on the road network and any anticipated road network upgrades.  These scenarios allow for the impacts of the proposed development to be quantified and assess any road network upgrades required.  The results of this process are incorporated into a report to document the modelling process.

The key benefits of the microsimulation modelling include

  • Able to model large areas including multiple roads / intersections.

  • Better analysis of the interaction between multiple intersections.

  • Allows for detailed traffic signal modelling, including demand based signal phasing / timing.

  • Incorporates public transport services including buses and tram / light rail.

  • Accurate results due to the rigorous Calibration & Validation process.

  • Visual simulation outputs allow for better articulation of issues / solutions to stakeholders.

 

Case Study:

Quantum Traffic has recently completed a microsimulation project as a traffic modelling consultant in Canberra for a new suburban school. The model covered a large area including three vital arterial roads and 18 intersections.  Critically, a section of the arterial road network included the recently completed Canberra light rail.

 

A key element of the Calibration & Validation stage was the assessment of the model against traffic data collected during the COVID-19 pandemic.  We utilised a range of data sources to ensure that the model was not impacted by lower traffic volumes associated with various government implemented lockdowns.

The development modelling included an allowance for surrounding development, including a large residential subdivision with 1,500 dwellings.  Growth on the broader road network was established from the Canberra Strategic Transport Model (CSTM).

Models scenarios were developed for 2023 and 2031 to assess the impacts into the future and recommend road upgrades to support the school's development.
