About

I am a motivated, solution driven, systems engineer specialising in the field of Intelligent Transport Systems and in particular, in the areas of advanced public transport and traffic management systems. Many years back, while contracting for the Roads and Traffic Authority of NSW (now part of TfNSW), I developed a prototype of the Public Transport Information and Priority System (PTIPS). With the support of the organisation and the contribution of a number of capable and dedicated colleagues, we grew PTIPS into a comprehensive system that tracking over 5000 buses in NSW providing real time arrival information to passengers and performance reports to both operators and authorities. The system also issues priority requests at signalised intersections on behalf of late vehicles to improve their adherence to their schedules. Working alongside the pioneers who developed the Sydney Coordinated Adaptive Traffic System (SCATS) offered exposure to the field of traffic engineering and led to a balanced approach to traffic signal priority that was put on display through the SCATS Priority Engine (SPE) that I played a major role in its development. My engineering background, my analytical abilities, my software development skills, and my degree in economics allowed me to contribute to the design, development, testing, evaluation and valuation of PTIPS and the SPE. Outside work, I share with my wife, two lovely boys who brighten my life. I like socialising, soccer, squash and other sports. I also like to enjoy good food and wine.

Experience

  • Technical Support Business Analyst at CONSAT TELEMATICS AB
    Mar 2024 - Present · 2 yrs 5 mos

  • Senior Intelligent Transport Systems Specialist at JYW Consulting
    Sep 2023 - Mar 2024 · 7 mos

    Carried out Cost Benefit Analysis of the Domain Tunnel False Ceiling Removal project including the utilisaiton of a traffic flow model to assess the costs of a potentially full or partial closure of the tunnel due to an incident. Developed a Python based tool to assess the efficacy of priority requests issued to the SCATS Priority Engine (SPE) for public transport vehicles based on SPE and public transport operational data. The tool is currently being utilised for evaluation of SPE based trials in Auckland/NZ.

  • Senior Developer at Prioritize Pty Ltd
    Mar 2015 - Sep 2023 · 8 yrs 7 mos

    Main contributor to the analysis/design/development/testing/evaluation of the SCATS Priority Engine (SPE). The SPE allows clients to request SCATS signal priority on behalf of certain types of vehicles such public transport buses and light rail, freight vehicles, and emergency vehicles. The SPE is operational in the state of NSW comprehensively in the city of Wollongong and some parts of Sydney. I rollout to additional SCATS sites is underway. The SPE was also trialled in the city of Adelaide, SA, and in Auckland, NZ and earlier this year, it was attempted as alternative mode of priority for the new City-South East Rail Line (CSERL) with promising results. Developed the SCATS Test Harness, a Python based tool, offering simulation testing of SCATS algorithms. The tool utilises the SCATSim model allowing for faster than real time execution of fully repeatable tests and allows a tester to fully configure the scenarios including specifying verification outcomes and reporting on the success, or otherwise, of the test runs.

  • Senior Development Engineer at ConTrace Proximity Tracker
    Jan 2020 - Aug 2020 · 8 mos

    ConTrace Proximity Tracker is pursuing a solution to automate the process of tracing the contacts of people who are infected with COVID 19 (and similar widely spread diseases) through the use of BLE technology on smart phones. The aim is to notify these contacts for testing and isolation purposes as well accessing the contacts of these contacts for further notifications. I am a main contributor to the analysis and design of the system including the data model. I am also contributing to the development of the web based backend of ConTrace on AWS. The aim is to deliver a beta version within few weeks.
