i dont know how viable it is to have shuttles on west/main/east mall. these streets are already very pedestrain-friendly. at the hour, it's a hassle driving along west and east mall as students walk from class to class, constantly crossing streets. and don't even think about main mall, it's bevy of students on the sidewalks, on the roads, the boulevard... and at the north end u have the nice courtyard in front of the koerner library, i would hate to see any sort of automotives there.
basically, it's not needed. classes of a certain faculty are clustered around a certain area. arts in the north, science in the center, engineering in the south, forestry in the deep south, and the rest are to insignificant for me to care about ;P. but yes, there's the occasional next class which is all at the other end of campus, but that shouldn't take more than 10mins, hence one hour class end ten minutes short of an hour. unless you're an unfortunate engineer-to-be who has an engineering class near the engineering crain after his english class in buchanan, u'd just have to suck it up
but the bottom line is that it would be quite difficult(to go through the masses of students) and impractical(as shuttles would have to be very frequent around the hour and infrequent between the hour. so what are the drivers gonna do then?) to impliment shuttle services on these routes.
but it's a good idea nevertheless. i always thought that a leveled escalator(the ones u find in airports on long stretches of walk) would be cool thing to impliment onto main mall. but the weathering of it and other whatnots of it would probably make that a bad idea...
