Abstract:

The content of timetable synchronization in the last period includes not only a guarantee on network accessibility, but also a reduction on transfer waiting time. Given that the connection relationships among trains are unfixed, binary variables are introduced along with penalty coefficients to provide an accurate representation of the transfer relationship of passengers in network. By adjusting trains running times, station dwell times and headways among trains, a model can construct high-quality timetables of the last trains’hour that minimize transfer waiting times with the distribution characteristics of transfer passengers. Then the CPLEX is used to solve the model. Finally, an empirical analysis of Beijing rail transit network is made to invalidate the validity and accuracy. Results show that: the model can improve the synchronization significantly compared with the current timetable; and it can provide a decision support to network operation in urban rail transit network.
