DESCRIPTION:Prof. Hong K. LO\, GREAT Smart Cities Institute of the Hong K
 ong University of Science and Technology\nAbstract\nZonal-based flexible b
 us service (ZBFBS) is a class of demand responsive door-to-door transit se
 rvice\, wherein the service area is divided into zones and services are ar
 ranged via zonal routes with detours within each zone to pick up and drop 
 off passengers. Service requests are aggregated by zonal OD pairs\, time w
 indows\, and the number of passengers per request. This presentation will 
 address the design of ZBFBS with the stochastic programming approach to ac
 count for passenger demands’ spatial (origin-destination or OD) and volu
 me stochastic variations over time. Two types of two-stage stochastic prob
 lems with recourse are formulated\, one for the frequency-based approach t
 o maximize the expected profit minus detour cost\, and one for the schedul
 e-based approach to include the time dimension. Finally\, a bi-level frame
 work is proposed to jointly optimize the zonal design and flexible bus ser
 vice strategy. The zonal design and ZBFBS strategy are validated in instan
 ces constructed based on real data in Chengdu\, China.\n\nShort bio\nProfe
 ssor Hong K. LO is Dean of Engineering\, Chair Professor of Civil and Envi
 ronmental Engineering\, and Director of GREAT Smart Cities Institute of th
 e Hong Kong University of Science and Technology. His expertise includes d
 ynamic transportation system modeling\, traffic control\, network reliabil
 ity\, and public transportation analysis. He has published extensively in 
 the transportation literature and was selected as one of the Most Cited Re
 searchers in Civil Engineering in the Academic Ranking of World Universiti
 es (ARWU). Professor Lo is very active in the transportation community\, f
 or instance\, elected as Convener of the International Scientific Committe
 e of the conference series Advanced Systems for Public Transportation (CAS
 PT)\, serves as Founding Editor-in-Chief of Transportmetrica B: Transport 
 Dynamics\, Managing Editor of Journal of Intelligent Transportation System
 s\, and on the editorial boards of many international journals. Professor 
 Lo was awarded the prestigious triennial World Conference on Transportatio
 n Research (WCTR) Prize and Eastern Asia Society for Transportation Studie
 s (EASTS) Outstanding Paper Award\, and HKUST School of Engineering Resear
 ch Excellence Award.\n\nSandwiches are offered at the end of the seminar.\
