Harvard's Shuttle Service redesigned its schedules this year to accommodate students' needs. But after a month's experience with the new timetables, not all undergraduates appreciate the changes.

During the summer, Shuttle Services made significant schedule changes on its Currier and Mather House routes, adding new times and shifting others so that buses arrive at more regular times.

Some upperclass students say the new system fixes gaps in the service.

"Last year you could not get back to the Quad between 3:50 p.m. and 4:30 p.m. whereas this year you can," said Hamilton H. Hicks '01 of Currier House.

But others have voiced complaints about the new system, saying they fear that shuttles near the top of the hour will be quickly filled, forcing students to walk.

"They are simply not enough shuttles when the demand is high," said Cabot resident Wesley T. W. Shih '01.

"I just hope that less people end up walking as a result of the revamping," wrote Pforzheimer House resident Fabianna S. Del Canto '02 in an e-mail message to Pfoho-open, a House-wide mailing list. "The volume of students taking the shuttles is not regularly spread out. Shuttle service should reflect this."

Last year, Quad residents could count on five shuttles around 10 a.m. This year there is one at 9:50 a.m. and only two at 10 a.m.
