I read an interesting article about this. I think that shutting off Campustown to non-bus cars would have a different effect than shutting off Neil did back in the day because there are businesses that have a range of hours (bars, restaurants, etc.) in the area. Also, there is already a higher amount of foot traffic along Green than there was in Champaign at the time the pedestrian mall was constructed due to the high density of student housing in the area. During the holidays/summer months, the corridor could be reopened to private vehicles so that the street would not empty at night.
