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.

Prof. Chow involved in NYCx Climate Action Challenge

NYCx, the Mayor’s Office of the Chief Technology Officer, announced the winner of the Climate Action Challenge in 2017-2018, where Prof. Chow was involved as a judge for evaluating the finalists:

New book by Prof Chow to be published by Elsevier

Elsevier is publishing “Informed Urban Transport Systems: Classic and Emerging Mobility Methods toward Smart Cities” by Prof. Joseph Chow in August. Pre-orders are now available:

https://www.elsevier.com/books/informed-urban-transport-systems/chow/978-0-12-813613-3

The objective of the book is to serve as an indispensable guide of classic theories in urban transportation systems science while tackling emerging issues like shared mobility services, data privacy, city monitoring, and dynamic decision processes. Chow was supported by the NSF CAREER award. 

 

New research published at Journal of Geographical Systems

For city agencies interested in operating online dashboards to monitor mobility through vehicular GPS data, one obstacle is having computationally efficient GIS tools that relate changes in travel patterns to specific points of interest (e.g. querying adverse weather impact on traffic at the airport, or at a downtown area) in real time. We demonstrate a new technological solution using taxi GPS data from Beijing. The tool is available on Xintao Liu‘s GitHub account (https://lnkd.in/dkHpeKa).

The paper is available here.  DATATANG provided the real-time GPS data used in this study. Prof. Chow was partially supported by the C2SMART University Transportation Center. 

Visiting Scholars and Summer Researchers

(comic courtesy of friends on social media)

Summer is upon us once again. As with previous years, we will have several researchers joining us for the summer as visiting scholars or graduate researcher assistants (on top of the PhD student researchers, the summer undergraduate researchers, and ARISE students that we employ). 

Dr. Tai-Yu Ma will be visiting us from LISER for the second of his three year visiting scholar program. Last year we collaborated on dispatch/positioning algorithms for bimodal shared taxi and public transit service. 

Prof. Daniel Rodriguez-Roman from UPRM is making a shorter summer stay at NYU through the Faculty Resource Network. We will be collaborating on public transit network design problems (sorely needed as the MTA plans to redesign the bus network!). 

In addition, Assel will continue to work in our lab this summer, while one of our incoming Fall 2018 PhD students, Anthony Haoran Su, will be joining us from Berkeley to start earlier in the summer. Milos Balac, a PhD student of Prof. Kay Axhausen at ETH Zurich, will also be visiting for the summer to help us with our MATSim model development. Welcome, Anthony and Milos!

Looking forward to a productive and fun summer!
