Table 2.

Modeled estimates for initial time investment, rate of increase in commute time per mile traveled, and differences in overall commute time (for key distances) by mode of transportation taken to attend HIV care visits among a convenience sample of HIV-positive MSM linked to care in Atlanta, Georgia, 2012-2013.

Mode of transportation	Initial investment (minutes)	∆ Commute time per mile traveled (minutes)	Modeled commute time (minutes) for miles traveled
Mode of transportation	Initial investment (minutes)	∆ Commute time per mile traveled (minutes)	1 mile	5 miles	10 miles	15 miles
Public^a	26.5 (23.6, 29.5)	3.0 (2.8, 3.3)	29.5	41.7	56.9	72.0
Private^a	6.2 (4.5, 7.9)	1.0 (0.9, 1.1)	7.2	11.4	16.5	21.7

^a Change in modeled commute times by mode of transportation for key travel distances, miles, listed in table: 22.3 minutes, 30.3 minutes, 40.3 minutes, 50.4 minutes.
