Route and coverage changes went in effect Monday for several routes.
In addition, two new park-and-ride lots on Jones Ferry Road and Friday Center Drive off N.C. 54 will soon open.
Debby Freed, UNC transportation demand management coordinator, said the Jones Ferry lot is scheduled to open in late September or early October, while the Friday Center lot is scheduled to open in October.
Chapel Hill Transit Director Mary Lou Kuschatka said the JFX and FCX routes will serve the two new lots, which will be free to park in during the day.
Kuschatka said that since the transit system became fare-free in January, officials have been forced to modify schedules to accommodate the spike in ridership.
"We made a lot of timetable adjustments," she said. "We are a victim of our own success."
She said ridership was 56 percent higher in May 2002 than May 2001 and was 73 percent higher in July 2002 than July 2001.
She said the July spike in bus ridership shows the service is not ignored when students leave town for the summer.
"It is not only students taking advantage of the fare-free ridership, but it's the whole community," she said.
