Timetable Synchronization for Rail Mass Transit

Abstract:

In public transit systems, passengers would like to interchange between

different lines with minimal delay. We propose a mixed-integer-

programming optimisation model for this schedule-synchronisation

problem for non-periodic timetables. The model minimises the interchange

waiting-times for all passengers by adjusting the trains’ run-times, dwell-

times, dispatch times and headways. A novelty in our formulation is the use

of binary variables which enable the correct representation of the waiting-

times to the “next available” train at the interchange stations. We also

discuss an optimisation-based heuristic for the model. We have tested our

algorithm for the Mass Transit Railway (MTR) system in Hong Kong, which

runs six railway lines with many cross-platform interchange stations.

Preliminary numerical results indicate that our approach improves the

synchronization significantly compared to the current practice of using

fixed headways and trip times. We explore the trade-offs among different

operational parameters and flexibility and their impact on overall passenger

waiting-times.
