The objective of this study is to evaluate the ticket service efficiency of Mass Rapid Transit
stations. The ticketing point within the MRT station is a junction or bottleneck point of travel within the
stations. The services include the automatic ticketing and ticketing by employees. The study evaluates
the ticket service system at Sukhumvit station, which is the busiest MRT station especially during rush
hours. Since last year, the ticket service queuing systems have been modified from the multi-channel
service with multiple queues to multi-channel service with single queue. This study develops a
microscopic traffic simulation to model two scenarios (before-and-after) of ticket service systems and
to compare the service efficiency between two models. The results show that changing the ticket service
queuing system from multiple queues to single queue can increase the space utilization of the waiting area by 28 percent, and reduce the passenger waiting time if the passenger demand is high (about 2,000
passengers per hour). However, if the passenger demand is low, then the waiting time of two scenarios
is about the same.
