SPEAKER:

Professor Chao-Yang WANG Electrochemical Engine Center (ECEC)

The Pennsylvania State University


DATE & TIME: 9-December-2022 10:30 am (HKT)/ 8-December-2022 09:30 pm (EST)


ORGANISED BY:

Institute of Transport Studies, The University of Hong Kong


ABSTRACT:

Mass adoption of electric vehicles (EVs) for decarbonization is presently hindered by battery safety, high cost, and low utilization of critical raw materials. Today’s lithium ion batteries (LiBs), originated from application to man-portable electronics, are not designed to exhibit safety, lifetime and operational robustness required of machine-like applications like EVs. For example, thermal runaway in LiBs with highly volatile and flammable electrolytes caused General Motors’ vehicle recall of $1.8B loss in 2021. Same batteries also experience severe degradation in surging air temperatures and will not survive hot summers. In this talk, I will present the development of heat-tolerant batteries for stable operation at elevated temperatures, much enhanced safety, and greatly simplified thermal management, paving the way to transport decarbonization. Profoundly, this development unveils a new design paradigm for EV batteries without having to trade-off among energy, power, safety, lifetime, and cost.

SPEAKER:

Prof. Daniel Sperling NAE, University of California, Davis


DATE & TIME: 27 September 2022 (Tuesday), 10:00 – 11:00 (Hong Kong Time)


ORGANISED BY:

Institute of Transport Studies, The University of Hong Kong


ABSTRACT:

Passenger transportation has seen little systems innovation for half a century. That is now changing. The ubiquity of smart phones is enabling the commercialization of a range of new mobility services, rapid advances in battery technology are enabling electrification of vehicles; and rapid advances in digital technologies is enabling automation of vehicles. The challenge is to integrate these innovations and direct them toward the public interest in a timely manner. Professor Sperling will investigate pathways of change for transportation, building on his research and policy experiences.


ABOUT THE SPEAKER:

Professor Daniel Sperling is Distinguished Blue Planet Prize Professor of Civil Engineering and Environmental Science and Policy, and founding Director of the Institute of Transportation Studies at the University of California, Davis (ITS-Davis). He has held the transportation seat on the California Air Resources Board since 2007 and served as Chair of the Transportation Research Board (TRB) of the National Academies in 2015-16. Among his many prizes are the 2018 Roy W. Crum award from TRB, its highest research award; and the 2013 Blue planet Prize from the Asahi Glass Foundation Prize for being “a pioneer in opening up new fields of study to create more efficient, low-carbon, and environmentally beneficial transportation systems.” He served twice as lead author for the IPCC (sharing the 2007 Nobel Peace Prize), testified 8 times to the US Congress, and has authored or co-authored over 250 technical papers and 13 books, including Three Revolutions: Steering Automated, Shared, and Electric Vehicles to a Better Future (Island Press, 2018). In 2022 he was inducted into the National Academy of Engineering.

Ride-Sourcing Systems & Multiple-Objective Online Ride Matching


DOWNLOAD LECTURE POSTER

SPEAKER:

Dr Hai WANG Singapore Management University, Singapore


DATE & TIME:

June 28 (Tuesday) 11:30-12:30 HKT


VENUE:

Room 632, 6/F, Haking Wong Building, The University of Hong Kong


ZOOM:

https://hku.zoom.us/j/97369816828 (Meeting ID: 973 6981 6828)


ABSTRACT:

We propose a general framework to study the on-demand shared ride-sourcing transportation systems and summarize the relevant research problems in four areas, namely, demand, supply, platform operation, and system problems. We then focus on the online matching problem, in which the platforms match passengers and drivers in real-time without observing future information, considering multiple objectives such as pick-up time, platform revenue, and service quality. Given stationary and non-stationary decision scenarios, we develop efficient online matching policies that adaptively balances the trade-offs between multiple objectives in a dynamic setting and provide theoretical performance guarantees for the policy. Through numerical experiments and industrial testing using real data from a ride-sourcing platform, we demonstrate that our approach can arrive at a delicate balance among multiple objectives and bring value to all the stakeholders in the ride-sourcing ecosystem.
