Dr Gary Au is an Adjunct Senior Research Fellow in Civil Engineering at Monash University applying artificial intelligence to enhance the performance of transport systems.

Traffic congestion

One research projects uses both real and synthetic data for training supervised deep learning object detection algorithms such as YOLOv9 (https://github.com/WongKinYiu/yolov9) and Facebook AI Research’s Detectron2  (https://github.com/facebookresearch/detectron2) to detect, classify, track and reidentify vehicles on road networks in real-world video imagery across multiple cameras. In this research the characteristics of synthetic data are identified to enhance correct detections and classifications and minimise false positives across real-world congestion, weather and lighting conditions. The overall aim of this work is to understand how traffic congestion emerges and evolves over time, so that congestion mitigation strategies can be developed.

Route optimisation, road pricing and parking simulation

Another research project involves route optimisation. This work explores parking behavior using SUMO, the Simulation of Urban Mobility (https://github.com/eclipse-sumo/sumo) and the minimisation of cruising in parking using different search strategies.

In addition to developing agent-based simulations to explore travel and parking behavior, he also conducts long-term empirical studies on the economic impacts of parking pricing; and studies dynamic parking pricing.

Of related interest is using AI to develop road pricing protocols for optimising traffic flow.

Transport Psychology

In transport psychology, he has studied prospect theory and decision making under risk and uncertainty.

Organisational Psychology

Other broader interests include researching the impact of AI on work design and organisation including job displacement and the creation of new job roles. For the transport industry, this includes the introduction of autonomous vehicles including driverless trucks and robotaxis, the education and skills required to safely manage AI-based transport systems in transport agencies, and more broadly the strategic workforce planning required to support a transition to an AI-based working world.

 

He received his BSc (with Honours) degree (1994) and his two PhDs (Physics (1996) and Psychology (2013)) from The University of Melbourne.
