More people are riding Arlington’s ART buses more often, County Board Chair Mary Hynes said earlier this week.

According to statistics quoted by Hynes, ART is on track to serve 2.5 million riders for the 12 month period ending this June. That’s a marked increase from just seven years ago, when ART bus ridership was just under 800,000 during financial year 2005.

Hynes said 1.2 million passengers rode ART from July to the end of December 2011 — a 14.5 percent increase over the same time period in 2010. ART now serves more than 9,000 passengers every weekday, versus 8,000 a year ago.

The transit service is planning to add additional service to the ART 42, 75 and 77 routes, according to Hynes.
