This is a job for a skilled administrator who works with lots of circles within circles and some tangential agencies.  The Commission on Transportation (COT) advises the DOT Director on matters within the jurisdiction of the DOT. The Oahu Metropolitan Planning Organization, commonly called OahuMPO is an important participating agency. These guys collectively could make a real difference.  The traditional problem with the DOT  is that they control so much money that they do what they want with very little little concern for public opinion or even political pressure.  I hope that the new guy has better hearing than the previous directors.
