On December 17, 2019, in the roomA716 of the New Main Building, Assitant Prof. Zhibin Chen, at New YorkUniversity Shanghai, was invited to make an academic lecture on “PathControlling of Automated Vehicles for System Optimum on Transportation Networkswith Heterogeneous Traffic Stream”. More than 30 professors and students fromthe SEM attended this lecture.
In the future, when trafficstreams comprise a mix of conventional and automated vehicles (AVs), AVs may beemployed as mobile actuators to regulate or manage traffic flow across an urbanroad network to enhance its performance. Prof. Chen reports a path-controlscheme to achieve the system optimum (SO) of the network by controlling aportion of cooperative AVs (CAVs) as per the SO routing principle. A linearprogram is formulated to delineate the scheme and determine the minimum controlratio (MCR) of CAVs to achieve SO. The properties of the MCR are mathematicallyand numerically investigated. Numerical examples based on real-world networksreveal that the SO of most of the tested networks can be achieved with an MCRbelow 23%. Considering the low market penetration of AVs at early stages oftheir deployment, we further investigate a joint path-based control and pricingscheme to replicate SO. Numerical examples demonstrate the remarkable synergyof these combined instruments on reducing the MCR with little collected tollingrevenue. His clear and in-depth lecture has benefited everyone, and wassuccessfully concluded in a warm atmosphere.
Zhibin Chen, an AssistantProfessor Faculty Fellow of Engineering at NYU Shanghai. Prior to thisappointment, he was a research fellow in the Department of Civil andEnvironmental Engineering at the University of Michigan,Ann Arbor. Dr. Chen’s research goal is to identify, develop, and implementemerging technologies to achieve a safer, more efficient, and environment-friendlytransportation system. He was the recipient of the Stella Dafermos Best PaperAward and the Ryuichi Kitamura Paper Award at the 95th TRB Annual Meeting.
