The Influence of Passenger Queuing Disorder on Bus Stop Dwell Time

In China, the bus system is frequently-serviced, and vehicles often queue at stops due to the limited capacity of a berth. Passengers will show out a disorder when boarding on buses, which may affect the service time at stops. In this paper, the effect of disorder, in the form the number of queues, on bus dwell time is quantified, and our research results show that when boarding passengers are organized by a single queue, the service time per passenger is 1.724 s/pax; while when passengers are organized by two queues, the service time per passenger is about 1.433 s/pax, decreased by about 16.88%. However, when passengers are organized by more than two queues, the service time per passenger increases sharply to 1.903 s/pax. It suggests that the service efficiency can be improved when boarding passengers are organized by two queues but will worsen with the aggravation of disorder.
