Main Roads Western Australia (Main Roads) needed to upgrade and refine its existing production Proof of Concept (PoC) Network Performance Reporting System (NetPRes) in order to improve its services to road users. In conjunction with ASG, Main Roads determined the need for a modern cloud data platform that would provide a faster, more accessible, and scalable system that would give its Network Operations team a better view of the performance of major roads using Advanced Analytics and Machine Learning.



    Main Roads Western Australia (Main Roads) is an agency of the Government of Western Australia. Its role is to plan, build, maintain and operate Western Australia’s State Road Network valued at more than $47 billion.


    The main responsibility and key objective within the four strategic areas of focus from ‘Keeping WA Moving‘, is to reduce traffic congestion by ensuring efficient operation of road networks.

    One of the ways it achieves this is by collecting road sensor data from a range of sources including traffic light systems and third-party data vendors.

    The Main Roads Network Operations team process this data utilising NetPReS in order to get a view of the performance of major roads for every 15-minute period. Whilst the existing NetPReS system that ingested and processed road network data worked reasonably well, it was not effectively maintainable by Main Roads Analysts and was therefore becoming slowly less accurate. The system was also slow to query, with some reports taking over an hour to run. On top of this, the Network Operations team wanted to significantly expand the range and reach of NetPReS; for instance, adding coverage of local roads and including additional data sources.

    The existing platform was also not capable of performing advanced analytics and machine learning on the data. This was an integral part of the Main Roads strategy to improve its services to road users.


    ASG were engaged by Main Roads Network Operations group to perform an architectural analysis of the existing system and then to identify bottlenecks and opportunities for improvement and upgrades. ASG then developed a roadmap for the upgrade and improvement of NetPReS, developing a logical architecture for the upgraded system and performing a market scan to identify the most appropriate components and platforms.

    ASG then built a proof of concept to ensure the architecture and components were fit for purpose. After obtaining IT approval for the technology, including arranging for new cloud environments and standards, ASG delivered a modernised data platform. The end solution was a world class cloud data platform built on Microsoft Azure that would allow Main Roads to ingest data from multiple and expandable data sources, process it, and store it for use in ongoing reporting and analysis.

    Graham Jacoby, Network Operations Analysis Manager at Main Roads said,

    “The system has enabled us to increase our number of data sources, with the data being more accurate and detailed.

    For example, the system now enables us to track to a high level of detail the congestion costs experienced by road users and has given us greater visibility across road networks which assists us with post project evaluations.”

    Jacoby explained that these improvements help the organisation more accurately validate the impact of actions taken to improve the road user experience, to ultimately help them deliver on their business objectives.

    “Our goal at Main Roads WA is ensure road users are safe, that they are kept informed of incidents or congestion, and that we continue to improve the performance of our road networks,” said Jacoby.
