The morning of July 15, traffic research institute professor at Leeds university , traffic simulation field internationally renowned scholar, Dr Ronghui Liu with the invitation of School of Civil Engineering and Transportation in South China University of Technology presented an academic report that themed the path selection and the dynamic model of signal control to teachers and students. The teachers and students of traffic engineering and department of transportation attended this report.
Reporting Spot
Professor Liu taught the problems of travelers route choice in transportation planning, and traffic signal control and dynamic interaction and its analytical model of route choice, and focuses on the different signal control strategy on the path selection and the response mechanism of driving behavior, as well as the critical conditions for steady state transition of the system under stable demand.
She pointed out that the research results show that the adaptive control can significantly reduce the vehicle delay and queuing length of single intersection. However, from the angle of the traffic network, adaptive control will increase the travel distance of the whole network traveler, so using regional signal control should consider people's dynamic route choice behavior to weigh the system travel costs.

Professor Liu Ronghui personal profile：
Liu Ronghui, Ph.D, Professor of Research Institute of transportation at University of Leeds
Social part-time: IEEE transaction on Intelligent Transportation Systems Associate Editor, IET Journal of Intelligent Transport Systems journal Editorial Committee member, International Symposium on Transport Simulation conference series founding member, Beijing JiaoTong University professor emeritus.
Her main research direction is to develop computer microscopic traffic simulation model, the analysis of the dynamic and complex travel behavior of traffic network and traffic disruption. She developed a microscopic simulation model of DRACULA and these model has become the only tool for research about the development of the blue sky and testing new ideas. Her research field in the study of traffic developed a lot of topics, such as traffic flow analysis and travel behavior modeling, ICT and intelligent transportation, as well as the public transport operation and reliability analysis. She is particularly interested in the relationship to these topics, as well as the estimate, design and evaluation of their methods of network effects. Her paper has been widely published in the international peer review magazine, and by the European Commission, Volvo Research Fund, UK Research Council, the Ministry of Communications Highway Agency, London, Department of the Ministry of Communications and Transportation Consulting and has been supported by local institutions.
