On May 10, 2019, The 3rd Southwest Jiaotong University Transportation Management Science Symposium was held by School of Transportation and Logistics at Southwest Jiaotong University, the National Engineering Laboratory of Integrated Transportation Big Data Application Technology, and National United Engineering Laboratory of Integrated and Intelligent Transportation. The invited guests included Yang Hai, Chair Professor of Hong Kong University of Science and Technology, former Editor-in-Chief of Transportation Research Part B, Yin Yafeng, Professor of University of Michigan, Editor-in-Chief of Transportation Research Part C, Meng Qiang, Professor of National University of Singapore, Editor-in-Chief of Transportation Research Part E, Yu Yugang, Dean of School of Management, University of Science and Technology of China, Zhang Hongjun (Michael Zhang), Professor at the University of California, Davis, Anthony Chen, Chair Professor at the Hong Kong Polytechnic University, Nie Yu, Professor at Northwestern University, Deputy Editor-in-Chief of Transportation Science, and Han Ke, Associate Professor at Imperial College London, and Wang Hai, Associate Professor at Singapore Management University. This academic seminar was presided over by Liu Xiaobo, Dean of School of Transportation and Logistics at Southwest Jiaotong University.
At the beginning of the meeting, Professor Sun Zhanbo of Jiaotong College took the stage to give a speech. The title of his report was "Cooperative decision-making for mixed traffic and microscopic right-of-way trading mechanism". Dr. Sun proposed the theoretical framework, model and solution of hybrid traffic flow collaborative decision-making control, and gave examples of simulation experiment, explained the micro right-of-way trading mechanism, and indicated the ultimate goal of the research.
Subsequently, Han Ke, an associate professor in the Department of Civil and Environmental Engineering at Imperial College London, gave an academic report entitled "Exploring urban air quality with MAPS-Mobile Air Pollution Sensing". Based on urban air quality monitoring and current related research, Dr. Han proposed a high-density and high-precision urban air micro-environment perception system based on fixed and mobile terminals. This is the first proposal to use generalized features to capture air pollutant inter-city regional transmission, increase accuracy while reducing the risk of overfitting, and at the same time provide a scientific basis for traceability of pollution outside the city.
Subsequently, Associate Professor Xie Jun of Southwest Jiaotong University reported on "Algorithms for frequency-based transit assignment problems" and shared research and analysis on traffic travel models. The comments of the guests provided new directions for Dr. Xie's research in this field. Dr. Cao Peng paid attention to the problem of traffic state estimation and traffic flow optimization, and reported on "Enhanced traffic data collection and analysis of instrumented vehicles: collection, efficiency and lane-based traffic estimation". Fu Heng, a doctoral student at the School of Transportation and Logistics, focused on the free-riding phenomenon in supply chain management. The guests at the meeting expressed that the issues raised in the report can be further explored and deepened.
In the afternoon, Nie Yu, professor at Northwestern University and associate editor of Transportation Science, gave a report entitled "Auction-based permit allocation and sharing system (A-PASS) for travel demand management." Dr. Nie and the guests at the meeting discussed enthusiastically, and the experts put forward relevant feasible suggestions for follow-up research directions.
Next, Dr. Li Ruijie analyzed how to match carpool drivers and drivers in a fair and effective way to promote carpool participation. In this meeting, he made a report entitled "Pricing carpool rides based on schedule displacement". Dr. Lu Gongyuan made a report entitled "Optimizing autonomous vehicle trajectory in signal-free intersection: a MILP approach". Finally, Dr. Hu Lu cut into the three concepts of phase distribution, randomness of peak and peak duration, and traffic circulation system, and reported on the content of "Phase-type queueing network model in a randomly changing environment for traffic circulation systems". After each speaker shared his academic report, the guests at the meeting commented on these reports.
The discussion of this academic symposium was successfully concluded. During the meeting, new ideas burst out and new topics were discussed. With this platform, experts and scholars shared and exchanged research results in their respective research fields, and learned from each other. This academic seminar played an important role in promoting the academic and professional development of our school.
