Assigning Passenger Flows on a Metro Network Based on Automatic Fare Collection Data and Timetable

Table 2

Illustration of our approach’s accuracies for different categories of O-D pairs.

O-D pair category	O-D pairs		Trips
	120409	100.00%	3937275	100.00%
() With single route	43326	35.98%	2368217	60.15%
() With multiple routes
(2.1) With determinate PTTs	42611	35.39%	874857	22.22%
(2.2) With indeterminate PTTs
(2.2.1) With obviously different route expected travel times	6088	5.06%	281124	7.14%
(2.2.2) Some special O-D pairs (similar expected travel times)	10978	9.12%	128241	3.26%
(2.2.3) Some special O-D pairs (small flows)	12460	10.34%	24194	0.61%
(2.2.4) Others	4946	4.11%	260642	6.62%
Accuracy range	75.43%~79.54% in terms of O-D pairs
	89.51%~96.13% in terms of trips
