text: You have some good points, however, I must add that decades ago(as far back as Mayor Fasi) there was effort and allot of money put toward the 
  "Second City". To this day it has/was never developed like a true design(Think DisneyWorld) where people lived worked,shopped etc. in the same place.If you moved UH etc. now, you'd still have massive traffic because the majority of students, Faculty live "in town" and would then commute west! PS.also, unlike High schools etc. students in CCs are not bound to their district school. Everyone loves KCC and commute, even from Waianae, EWA, Kaneohe etc to go there. Hence a max6K campus often has 10K+ students while district CCs have only 2K.
