The main reason for heavy H-1 traffic is UH.  When UH is not in session, like now, traffic is good.  Well, OK anyway.  If we were building rail to alleviate traffic, it should go to UH, and construction should have started there and Pearl City simultaneously (to have the maintenance yard ready) so we could use it as it moves along.  I think most people will drive their cars hoping that the OTHER people will ride the rail, mainly because families have other tasks such as grocery shopping and children's sports.  It is difficult to use a Point A-B system, then have to get off and catch feeder buses.  If "OTHER" people are mainly UH students who will likely have fewer obligations and thus, use the rail, then it would work.  Getting west students out of their cars and on the rail would really help.  Of course, my solution would have been to make UH-West Oahu comparable to UH-Manoa to keep west students out west and off the freeway.  But that's another story.
