The subway itself has the advantages of high speed, large traffic volume, little interference from other traffic modes, and not easy to be affected by the weather. It has become the choice of travel mode for more and more residents. The subway line construction based on hot travel can better meet the requirements of fast, comfortable, less transfer and no congestion for tourists. At the same time, it can greatly reduce the traffic pressure such as traffic and parking in scenic spots, which is conducive to energy conservation and emission reduction. Therefore, good hot metro line planning has practical significance for urban development. The introduction of large and small routing schemes in this paper can, on the one hand, alleviate the problem of high train load rate and poor passenger comfort in crowded sections, on the other hand, reduce the waste of transport capacity in small sections of passenger flow, and save resources and enterprise transport costs. This paper first introduces the research background and significance of large and small routes, as well as the research status at home and abroad, then analyzes the factors that affect the setting of large and small routes, establishes the constraints of the model, and finally takes the train full load rate, departure frequency, minimum departure frequency, the number of short route stations as the constraints, and takes the train running distance and the total waiting time of passengers as the objective function. The linear weighting method, genetic algorithm and MATLAB software are used to solve two objective equations, the operating range of small routes and the departure frequency of trains with large and small routes. Finally, the feasibility of the model in real life is verified by taking the hot travel line of Chengdu Metro Line 1 as an example.
