Professor Wang Dianhai presented a keynote speech entitled "The Future of Traffic Signal Control from the Perspective of Data". Professor Wang Dianhai first sorted out the six stages of the development of traffic signal control system from the traffic data, and analyzed the characteristics of traffic data and control system in different stages. Facing the future traffic control, Professor Wang proposed that the future traffic data will realize the full identification of moving targets and the full network tracking, so as to support the real-time coordination and adaptive hybrid traffic control system of the network. Professor Wang also pointed out that the essence of traffic control is to control people, not to control the car, so people-oriented active control is the key research direction in the future.
Professor Guan Jizhen will present a keynote report entitled "Intelligent Transportation System Technology Evolution and Future Trends". Professor Guan first systematically explained the evolution characteristics and future development trend of China's intelligent transportation system technology, pointed out the important changes in the development connotation and concept of intelligent transportation system in the development process, and finally concluded that the three characteristics of future traffic control system are generalized control, collaborative control and multi-objective control.
Associate Researcher Hua Jingyi presented a keynote report entitled "Research on Dynamic Response Control of Intersection Signal with sense-controlled Interaction". Dr. Jingyi Hua first introduced the optimization calibration method of phase level signal control characteristic parameters in detail, explained the dynamic response control strategy of cycle level iterative feedback signal, and introduced the construction of test environment and model verification effect. Finally, she put forward the thinking of hybrid traffic flow control for future different levels of automatic driving.
In the roundtable discussion, the participants had a broad and heated discussion on the current situation of the traffic control industry, the needs of enterprises and new opportunities for industry-university-research cooperation. According to the status quo of the industry, Dr. Song Zheng from Tencent and Dr. Nie Xiaojian from Baidu pointed out that the current development of the transportation industry is extremely dependent on the support of big data of geographic information and traffic operation, but the data quality varies greatly among cities; Dr. Zhou Xiaopeng and Dr. Zheng Jianfeng believe that the current traffic signal control system needs a perfect operation and maintenance mechanism, and the high accuracy rate and high return rate of traffic data are the key to further improve the quality of traffic control.
Facing the needs of enterprises, Vice President Ma Xiaolong from Hisense hopes that the transportation industry can establish a comprehensive and systematic industry standard, and strengthen the cooperation between enterprises through data open source; Dr. Chen Ningning from Zhenye Superior Control believes that the industry urgently needs a unified traffic control evaluation system, which is the basis for optimizing traffic control. And the participants agreed that the technical personnel of traffic control is still very scarce, and it is hoped that the talent training of colleges and universities can be more close to the actual scene.
In view of the new opportunities for industry-university-research cooperation, Dr. Xiang Junping from Jereh introduced the relevant progress of JerEH Electronics' application of traffic collaborative perception and control in a networked environment; Professor Guan Jizheng and Professor Wang Dianhai pointed out that industry-university-research cooperation should be demand-oriented, future-oriented and application-oriented, and through the deep integration of the three, traffic signal control can stimulate new vitality.
After the roundtable discussion, the participants moved to the Shanghai International Automobile City Building and visited the construction of Shanghai Shuangzhi City on site. The staff of the new energy data center first introduced the construction and opening of the data platform, and showed the four main functions on site. The participants had in-depth exchanges with Motor City in terms of data protocols, data quality and application effects.
This seminar brought together a number of senior experts from academia and industry, from the dual perspective of traffic control theory and practical application, through special reports and roundtable discussions, brought a rich knowledge and forward-looking information, and promoted the theoretical research of traffic control system and industry-university-research cooperation.
On August 8, 2023, Professor Lo Kangjin, Dean of the School of Engineering, Hong Kong University of Science and Technology, and his team visited the Magic Subject Group of Tongji University for academic exchange. The participants of this academic exchange meeting include Professor Luo Kangjin and his team members, Magic research group Professor Ma Wanjing, Professor An Kun, Associate Professor Wang Ling, Associate Professor Yu Chunhui, Su Zicheng Distinguished researcher and research group students.
