Mobility-as-a-Service will only work if cities can evaluate markets of multiple operators, and consider not just ridership but also the incentives for transferring costs (fares, access/egress, wait time, in-vehicle time) between operators and travelers. Saeid Rasulkhani and Dr. Chow just published a new modeling framework that explicitly considers these trade-offs, developed with funding from NSF (CMMI-1634973).
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’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.
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.
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.
In addition to Anthony Haoran Su who joined as a new PhD student coming from Berkeley, we would like to extend a warm welcome to two new additions for the fall: new PhD student Reuben Juster who is joining us from Amazon and new MS student Patrick Scalise joining us from Harvey Mudd. Welcome to the BUILT lab!
