Dr. Sajjad Shafiei received his Ph.D. in Transport Engineering from Monash University. He joined Data61 as a postdoctoral research fellow in 2018. His research focused on estimating travellers’ movement patterns in urban networks. He has been involved in different engineering projects, such as the development of advanced dynamic traffic models, behavioural modelling and strategic four-step transport modelling. He is currently employing various machine learning techniques to support traffic simulations for short-term traffic prediction under non-recurrent incidents.
