On March 4th, Associate Professor Soyoung Ahn of the University of Wisconsin, Dr. Zhou Yang, and his party were invited to visit our base for exchanges.
On the morning of the 4th, Associate Professor Soyoung Ahn and his team visited the base station and smart car test site of our base, Weishui Campus, on the “Intelligent Network Link Queue Coupling Technology”, “Cooperative Lane Change Technology under the Internet of Vehicles”, “Dynamic Speed Limitation and The active management technology of traffic flow, etc., has conducted in-depth exchanges and discussions with young backbone teachers, doctoral students and master students.
In the afternoon, Associate Professor Soyoung Ahn gave a special report entitled "A stochastic modeling of traffic breakdown for freeway merge bottlenecks" to the participants in the base conference room. This report presents Professor Ahn's latest research findings, a probabilistic model of a new type of traffic flow collapse based on micro-driving behavior in a highway confluence bottleneck scenario. The study describes the gradual process from free-flow state to congested state by improving Newell's car-following model. At the same time, based on the characteristics of the model, a low-permeability intelligent network-connected vehicle active response traffic control method is proposed. After the special report, Prof. Ahn and the participating teachers and students had a discussion on topics such as “active flow control mechanism” and “the actual use of the mechanism in the traffic incident environment”. The content of the report was well received by the teachers and students and won warm applause. More than 30 young teachers and graduate students from the base participated in the seminar.
At 7 pm, Dr. Zhou Yang gave a special report entitled "Robust Local and String Stability for a Decentralized Car Following Control Strategy for Connected Automated Vehicles" to the base young teachers, doctoral students and master students in the conference room on the fourth floor of the School of Information. The report shows Dr. Zhou Yang's latest "Discrete Intelligent Network Connection Control Method Based on Dynamic Time-Varying Mechanical Control Delay and Communication Delay", and studies how to establish intelligent network in the environment of uncertain mechanical delay and communication delay. Vehicle control model, reasonable estimation of feasible parameters of control parameters. Dr. Zhou Yang conducted in-depth discussions with the teachers and students on the actual control of the test field intelligent network car. The atmosphere was lively, and the academic atmosphere was strong, and the discussion was warm.
