The 22nd COTA International Conference of Transportation Professionals (CICTP 2022)

As the core force of a new round of scientific and technological revolution and industrial transformation, artificial intelligence is promoting the upgrading of traditional industries, driving the rapid development of "unmanned economy", and has a positive impact on people's livelihood in intelligent transportation, intelligent home, intelligent medical care and other fields. This article focuses on the artificial intelligence development status and application prospect in the field of traffic control. By tracing the history of traffic signal control and artificial intelligence, analyzing the limitations of existing hardware and software architecture and the lag of the algorithm in the field of traffic control , to discuss how to apply artificial intelligence technology to traffic signal control system better, including front roadside unit, the middle signal control machine and the back end signal control server, so that traffic facilities can see, listen, say, calculate, think, make decisions and dispatch, to establish an all-round, multi-level traffic control "brain", make the road traffic control more accurate, more real-time and more convenient. At the same time, the application of artificial intelligence in the field of transportation such as driverless driving, intelligent dispatching, route planning and other applications is expanded, and the issues related to privacy protection, traffic laws, ethics and other that may be brought by artificial intelligence are considered, and the evasive measures and future development direction are discussed.
