all great ideas. singapore also has bus routes that do not overlap. each station has its own busses that only serve that station. apartments have businesses on the first and second floors where they employ many of the older residents getting subsidized rent. it works very well but the key is rent is 25% of take home pay. in hawaii it should b e 20%. this part is way too important to give to private developers. this has to be owned by us, the people, the government.
