In order to solve the problems of management lag and unreasonable resource allocation caused by the lack of extensive interconnection in traditional tourism traffic management, the system architecture of intelligent tourism highway platform is established. The new generation of information technology concepts such as geographic information systems (GIS), big data and artificial intelligence are introduced into the management of tourism highway, aiming at building an intelligent tourism highway platform integrating perception equipment, data communication, decision making center and visual interface. It realizes real-time perception of traffic conditions, efficient data communication, intelligent decision support and intuitive visual display, so as to improve the management efficiency, traffic safety and tourist experience of tourist highways. The results show that the study is of great significance for promoting the innovative development and sustainable development of tourism.
