ABSTRACT
Passenger's optimal path choice is one of the prominent research topics in the field of railway passenger transport organization. More and more different train types are available, increasing path choices from departure to destination for travelers are unstoppable. However, travelers cannot avoid being confused when they hope to choose a perfect travel plan based on various travel time and cost constraints before departure. In this study, railway passenger travel network is constructed based on train timetable. Both the generalized cost function we developed and the residual train capacity are considered to be the foundation of path searching procedure. The railway passenger travel network topology is analyzed based on residual train capacity. Considering the total travel time, the total travel cost, and the total number of passengers, we propose an optimal path searching algorithm based on residual train capacity in railway passenger travel network. Finally, the rationale of the railway passenger travel network and the optimal path generation algorithm are verified positively by case study.

Mentions: The proposed approach is illustrated with a railway timetable as shown in Table 2. Four trains run among cities a, b, c, d, and e. Residual capacities of all trains are shown in Table 3. The minimal train transfer times of the same station and different station in a city are 15 min and 30 min, respectively. Use the proposed approach to construct railway passenger travel network based on the railway timetable (Table 2), as shown in Figure 5. Suppose all the fare of transferring arcs among different stations ftarc = 30 CNY, the value of time tf = 12 CNY/h, and the parameters α = 0.8 and β = 0.2.
