Anthony Aalto says, "[Rail] will provide the spine for a development corridor that will allow us to finally halt the relentless suburban sprawl that is eating up our countryside at an alarming rate."  Unfortunately, rail won't do that.  It takes political will to do that, and it is in short supply.  As evidence, Koa Ridge in central Oahu was recently approved, extending suburban sprawl in the countryside.  Transit-oriented development along the rail line will make rush hour traffic along the H-1 corridor even worse because it will increase the population along the Ewa end of the rail line.  Most of those new residents who commute to town will take their cars, not the rail.  Instead of directing the increased population there, density should be increased in the Primary Urban Center.  The market would increase the supply of housing, resulting in reduced housing prices and the creation of affordable housing.
