Nowadays, to meet passengers' nighttime travel needs and stimulate urban nighttime economic development, subways in some megacities extend their operation hours. In the extended operation period, some routes connecting a given origin and destination (O-D) pair become unreachable which made the transit service providers can’t use the conventional method to analysis the passenger flow of plus-train in the extended operation period. This paper proposed a methodology for calculating the passenger flow of the plus-trains based on automatic fare collection (AFC) data and realized train timetable. Considering real-time reachability of the routes which connected an O-D pair, a weighted assignment function among the remaining reachable routes is provided. Then we calculate the passenger flow of each plus-train by estimating which trains were chosen. Initial case study on Shanghai metro shows that the proposed method works well, the calculated plus-train flow and actual survey results match more than 90% which could provide reliable passenger flow data for the optimization of the network plus-train schedule.
