Model study of urban tourism itinerary chain based on the background of big data

As China's economy continues to develop and people's living standards continue to improve, travel and tourism has become an important way for the public to relax and relieve the stress of life, and along with the introduction of smart tourism and the rapid development of information technology, new forms of tourism, mainly self-guided tours, have begun to emerge and flourish. This paper examines the optimisation of tourism routes to maximise the needs of contemporary people, taking into account the new contemporary fashions of routes and travel styles throughout history. In addition to planning viable and quality routes, people are provided with the best possible service and experience. This paper is guided by a new combination of research based on the context of big data, combining an in-depth study of computer modelling algorithms based on the creation of urban tourism itinerary chains.
