Visiting Guest Speaker

Dr Mohsen Ramezani  

Senior Lecturer with Transport Lab, 
School of Civil Engineering, University of Sydney

Date: Mon 28 August 2023


Dr. Mohsen Ramezani received the B.Sc. and M.Sc. degrees in electrical engineering (control systems) from the University of Tehran, Iran, in 2008 and 2010, respectively, and the Ph.D. degree in Transportation from École Polytechnique Fédérale de Lausanne (EPFL), Switzerland in 2014.

Prior to joining the University of Sydney as a Lecturer in Transport Engineering in 2016, he was a Lecturer at the Institute of Transport Studies at Monash University, Melbourne, Australia (2015-2016).

He is currently an ARC DECRA Fellow and Senior Lecturer with TransportLab at the School of Civil Engineering, with research interests in traffic modelling and control, traffic flow theory, ride-sourcing and ride-sharing systems, and automated vehicles.


The ubiquity of smart devices builds the foundation for emerging, fast-growing ride-sourcing companies (e.g. Uber, Lyft, DiDi) that disrupts how people and goods travel in cities. Ride-sourcing provides an on-demand mobility platform that acts as a two-sided market by matching riders (and goods) with drivers. The conventional models of ride-sourcing systems are based on equilibrium assumptions suitable for strategic decisions. This steady-state approach is not fit for operational decision-making where there is noticeable variation in the state of the system, denying the market enough time to balance back into equilibrium. This talk introduces dynamic non-equilibrium models and algorithms for on-demand mobility systems. The models and algorithms challenge the common shortcomings by addressing the market supply as earning-sensitive, independent contractors, and self-scheduling. The models enable to investigate how dynamic wages and fares set by the ride-sourcing service providers affect supply, demand, and states of the market, such as average waiting and search time, especially when drivers can freely choose when to start and finish working.
