Linxuan presented his research work, titled “An Integer L-shaped Method for Dynamic Order Dispatching in Autonomous Last-Mile Delivery with Demand Uncertainty” [URL], at the TRB Annual Meeting. Great job, Linxuan!

The SUM Lab received a seed grant from the School of Engineering and Applied Science. The grant will support the initialization of early research investigations into the path of infrastructural transition as the transportation system electrifies. Ultimately, we aim to draw for the societal implications for different evolving trajectories of how charging stations expand and gas stations phase out.

The SUM Lab member Ms. Bhagyashree Panda has been selected as a recipient of a 2022 Women’s Transportation Seminar DC Chapter (WTS-DC) ­­­­­­­­­­­­­­­Graduate Scholarship. Congratulations, Bhagyashree!

Linxuan presented his independent research work “An Integer L-shaped Method for Dynamic Order Dispatching in Autonomous Last-Mile Delivery with Demand Uncertainty” [URL] at an invited session on the Challenges and Innovations in Urban Logistics organized by Dr. Xu. Well done, Linxuan!

In addition, Dr. Xu made a flash talk titled “Empirical analysis of electric vehicles’ charging patterns: Case study from Shanghai” [URL] at Smart Cities Cluster Session. This work is in collaboration with colleagues at NYU Shanghai and Tongji University.

Linxuan’s paper, titled “An Integer L-shaped Method for Dynamic Order Dispatching in Autonomous Last-Mile Delivery with Demand Uncertainty” [URL], is peer-reviewed by the TRB Standing Committee on Freight Transportation Planning and Logistics and recommended for presentation at the TRB Annual Meeting in January 2023. Congrats, Linxuan!

Dr. Xu is selected by the Transportation Science editorial board to receive a Meritorious Service Award in appreciation of his efforts as a reviewer for the journal. The award is conferred by Transportation Science to recognize Associate Editors and reviewers who have offered exceptional service to the journal in the review process.

Transportation Science is the flagship journal of the Transportation Science and Logistics Society of INFORMS and is the foremost journal in the field of transportation analysis.

 

Quinn Mores, a senior high-school student at the School Without Walls (SWW), joins the SUM Lab as an intern for the upcoming Fall semester. He will work with Bhagyashree to establish a systematic framework for considering the equity issues around EVs.

The SWW is a small public magnet high school located on the George Washington University campus in Washington, D.C.

Dr. Xu gave a talk at the 2022 INFORMS Conference on Security on the trends of restaurant service demand amid the COVID-19 pandemic. This is collaborative work with his Ph.D. student Linxuan. The associated paper is currently under review.

Dr. Xu made a podium presentation at the 24th International Symposium on Transportation and Traffic Theory (ISTTT24) on his work A Generalized Fluid Model of Ride-Hailing Systems. This is a collaborative work with Dr. Xu’s co-authors from the University of Michigan and Didi Chuxing. The paper is published in Transportation Research Part B: Methodological [URL].

Since its launch in 1959 by the late Robert Herman, the International Symposium on Transportation & Traffic Theory series has remained the primary venue for discussing advances in the theoretical and methodological aspects of the interdisciplinary field of transportation and traffic systems science. It has been the premier gathering for the world’s transportation and traffic theorists.

COTA CICTP 2022 (originally planned to be held in Changsha, China) was held in virtual due to the pandemic. Dr. Xu chaired the session titled “Green Transportation Energy and Eco-driving Management”.
