Measuring Service Reliability Using Automatic Vehicle Location Data

Table 5

Assessment of service performance changes using different reliability measures.

𝜎2	PTI (PT*)	BTI (BT*)	RTI (RT*)	ERBTI (ERBT)
4	1.520 (45.0)	0.452 (14.0)	0.520 (15.4)	0.304 (9.0)
5	1.520 (45.0)	0.452 (14.0)	0.520 (15.4)	0.351 (10.4)
6	1.520 (45.0)	0.452 (14.0)	0.520 (15.4)	0.399 (11.8)

 *PT: planning time; BT: buffer time; RT: reliability time.
