In order to improve the integrated communication control and transmission capacity of rail transit, a rail transit integrated communication network planning model is constructed based on reliability index. The transmission model of rail transit integrated communication network is constructed. On this basis, channel equalization control method is used to obtain the channel output of rail transit integrated communication network. The Small World model is used to construct the network model of rail transit integrated communication network. Combined with emergency scheduling and balanced control method, the balanced control of communication network is carried out. By the method of balanced game of reliability index and the partition of regional grid and intelligent adjustment of output, the planning model of integrated communication network of rail transit is optimized, and the planning of integrated communication network of rail transit is realized. The simulation results show that the proposed method has high adaptability and strong balanced control ability, and improves the output connectivity and reliability of rail transit integrated communication network.
