Abstract:Faced with the situation that the theory and technology of urban road traffic control need to be broken through urgently and the advantages of multidisciplinary cross-research are highlighted, the development history and research status of urban traffic control are summarized, and the existing problems and future development are summarized and discussed. Firstly, the development stage of urban road traffic control in China is reviewed. Secondly, the domestic and foreign research situation of traffic signal control, traffic demand identification and traffic control simulation is summarized around road traffic control. Finally, the existing problems of traditional traffic control are discussed, and the evolution of new theories and technologies such as vehicle-road coordination, automatic driving and artificial intelligence in the future is summarized. The research emphasis and key problems in the field of traffic control are concluded.
