C2SMART research to be presented at INFORMS TSL Workshop in Vienna

Research from the BUILT lab on “Doubly-constrained rebalancing for one-way electric carsharing systems with capacitated charging stations”, from Ted Pantelidis, Li Li (NYUAD), Tai-Yu Ma (LISER), Joseph Chow, and Saif Jabari (NYUAD) has been accepted for presentation at the INFORMS TSL Workshop in Vienna. The workshop’s theme is ““Transportation in the sharing economy”. The project is funded by C2SMART with data shared by BMW ReachNow.

Preliminary work for this project was previously presented at the 98th Annual Meeting of the TRB in Washington DC.

BUILT Lab to present NSF research at TRISTAN X at Hamilton Island

The work from student researchers Saeid Rasulkhani and Ted Pantelidis will be presented at the Tenth Triennial Symposium on Transportation Analysis (TRISTAN X) on June 17-21 at Hamilton Island near the Great Barrier Reef in Australia. The NSF-funded (CMMI-1634973) research is entitled “A many-to-many stable matching cost allocation model for multimodal Mobility-as-a-Service”, where we develop a novel methodology to extend earlier work to handle cost allocation analysis for multiple operators splitting a traveler’s trip. This ongoing work has resulted in major breakthroughs in facilitating design of integrated services between different operators and transport agencies within a true “Mobility-as-a-Service” setting, providing to them a tool like how the classic “traffic assignment problem” helped roadway planning in the last few decades. We are finalizing our computational experiments and will be submitting this to a journal for publication.

Nick Caros’ work featured in a TEDx talk by NEXT co-founder Tommaso Gecchelin

Nick’s thesis work, which involves simulation of en-route transfers to better understand their impacts under different transit operating strategies, was recently featured in a TEDx TUM talk by Tommaso Gecchelin, a co-founder of NEXT Future Transportation.

Nick Caros was a MS student in the Transportation Planning & Engineering program in the Department of Civil & Urban Engineering. He worked as a research assistant in the BUILT lab through funding from C2SMART and completed his MS degree with a thesis in January 2019. He has one conference proceeding and 2 manuscripts under peer review in international journals from his time here.

BUILT lab to present at ISTTT 23 in Lausanne, Switzerland

Brian Yueshuai He and Prof. Chow’s work on “Optimal privacy control for transport network data sharing” has been accepted for a poster at ISTTT 23, the bi-annual international symposium on transportation and traffic theory. 

The International Symposium on Transportation & Traffic Theory series is since its first issue in 1959 the main gathering for the world’s transportation and traffic theorists, and for those who are interested in gaining (or contributing to) a deeper understanding of the field. The Symposium deals with both scientific and operational aspects of transportation and traffic, spanning all modes of transport, and covering freight as well as private and public transport.
In more 30 podium presentations the attendants will be informed about the latest scientific insights on transportation and traffic theory. For more information about the symposium, see here


New publication on designing autonomous vehicle car clubs

In this joint work with Prof. Allahviranloo from CCNY, we studied the design of autonomous vehicle fleets for households purchased shared ownership, like stocks, of each vehicle. Under such a system, owners can therefore trade stocks of these time slots, and the impact of a time slot on a user’s activity schedule needs to be accounted for. This work should be of interest to car manufacturers like Ford and GM as they move into these types of AV business models in the future.

Tai-yu Ma (presenter), Saeid Rasulkhani, Joseph Chow, and Sylvain Klein. An integrated dynamic ridesharing dispatch and idle vehicle repositioning strategy on a bimodal transport network.

Assel Dmitriyeva (presenter), Daniel Fay, Xuebo Lai, and Joseph Chow. Effect of routing constraints on learning in contextual bandit mobility-on-demand destination recommendation systems.

2018 Summer Research Presentations

Congratulations to our student researchers in summer 2018. This year we had two high school students and three undergraduates from ARISE and Undergraduate Summer Research, respectively.

The NYU Tandon School of Engineering conducts the Applied Research Innovations in Science and Engineering (ARISE) program since summer 2013. We had two ARISE participants this summer,  Chengyuan Wang and Annie Eng, who have spent the past five weeks to make practical contributions to our lab’s research objectives. They both gave brilliant presentations at the program’s concluding colloquium.

The UG Summer Research Program was initiated in 2007. This year, three students (Eric Gan, Carol Shlyakhova, and Ziyi Ma) work full time in our lab with their faculty mentors (Joseph Chow)  and other mentors (Brian He, Jinkai Zhou, and Saeid Rasulkhani) on various research topics while also participating in seminars presented by distinguished administrative and academic personnel.
