铁路客运中转径路是铁路客运通票的重要组成部分，标识了通票的途经径路。计算机发售通票业务过程中需要一些中转径路备选使用，这些备选中转径路是在一定合理性上计算出来的。本文结合中转旅客的必要需求，在“路网模型”和“变线模型”的基础上，综合考虑了中转里程短和换乘次数少这两方面因素，建立了优化计算中转径路更为完善的“换乘模型”，并提出了有效的求解算法，从根本上解决了中转径路的优化计算问题 Passenger transit route is an important part of the Passenger Railway Passenger Pass, marking the pass through the path. Some transit routes are required to be used in the process of computer offering pass business, and these alternative routes are calculated with certain rationality. In this paper, based on the necessary requirements of transit passengers, on the basis of “road network model” and “change line model”, considering the factors of short transit mileage and fewer transfer times, the paper established a more perfect route “Transfer model”, and put forward an effective solution algorithm, the fundamental solution to the problem of the transit path optimization calculation
