Busy bus stops are often the main bottlenecks of the bus systems, where buses often form long queues when waiting to enter the stop. These bus queues significantly degrade the overall quality of the bus service. Moreover, buses often dwell in a travel lane at a stop, and these dwelling buses will create temporary bottlenecks for the adjacent car traffic. The resulting car queues and delays can be large especially when the stop is located a short distance from a neighboring signalized intersection.
To solve these queueing problems, we formulated analytical models using distinct
Dr. Gu is now an assistant professor at the Department of Electrical Engineering, the Hong Kong Polytechnic University. He received his Ph.D. in Civil & Environmental Engineering from University of California, Berkeley in 2012. He also received his B.S. and M.Eng. degrees in Civil Engineering from Tsinghua University (Beijing, China) in 2002 and 2005; and his M.Sc. (in Industrial Engineering & Operations Research) and M.A. (in Economics) degrees from UC Berkeley in 2010 and 2011.
Dr. Gu’s research interests span over public transit systems, multimodal urban transportation systems, freeway traffic operations, queueing systems, and infrastructure systems management. He is especially interested in how various transportation modes including cars, buses, rail, and bicycles interact in urban networks, and how to optimally design and manage such a multimodal urban transportation system for the benefit of all.
His awards include a Gordon F. Newell Award for Excellence in Transportation Science (granted by the Faculty of Transportation Engineering at UC Berkeley) and a Chinese Government Award for Outstanding Self-Financing Students Abroad.
