2017 Honolulu Rail: Advice to the Legislature

As the Hawaii Legislature is debating yet another round of requests by the "on time and on budget but no accountability in sight" mayor of Honolulu to extend the General Excise Tax Surcharge for rail, I offer these comments:

• The best option since the expected costs for rail's construction surpassed $7 billion was to stop and demolish it. But that's a political non starter for the current regime.

• The second best option to avoid a $10+ billion dollar hole is to stop the rail at Middle Street. This should be doable at a cost of about $8 billion. The Middle St. station is at the intermodal center of Honolulu, thus rail can seamlessly connect to a BRT circulator (Kalihi, Chinatown, downtown), and express buses to UH and Waikiki.

• The recently floated Middle Street to UH on-street light rail option will get us past a $15 billion cost and will result in heavy in-town congestion and many accidents. In some places, the lane loss will be severe because of the need for space for stations. Honolulu is the most lane deficient city over one million population in the U.S. (e.g., lane miles per capita).

• A rail system cannot operate without a rail yard. Mayor Mufi Hannemann started the rail out west because he could not find space for an in-town rail yard. Where's the space for a light rail yard anywhere between Middle St. and UH? We can't put it at Middle Street because the revised sea level rise and tsunami exposure maps have placed it inside an inundation zone.

• Very few commuters will choose the proposed on-street light rail in town because car, taxi and Uber is door to door service and over twice as fast. Note that the rail EIS clearly states that in year 2030 with rail, all trips between Aiea and Ala Moana  will be faster by car than by rail. I should add that there is nothing that light rail will do in town that BRT would not do better with more flexibility, and cheaper.

The Legislature should not approve any extensions of the GET and it should pass a bill directing the city to handle current and future deficits with its own resources. This offers hope for some accountability and cost containment. The Legislature should also reduce the state share of the GET from 10% to 2%. These are the only reasonable actions by politicians who claim that care for the people.

2015 Traffic Accident Map of Honolulu

This is an interesting and useful result of an unofficial public-private partnership where the City and County of Honolulu provided a database of redacted accident records with geographic identification data and a private firm used geographic information system (GIS) expertise to provide a depiction and summary of these data by location. The 2015 Traffic Accident Map of Honolulu by the Law firm of Davis Levin Livingston lets one quickly identify traffic black spots.

For example, the portion of their map I captured above shows that the University of Hawaii area is generally light in crashes. Punahou Street near the freeway has a moderate amount of crashes. The set of blocks surrounding and including Ala Moana Cednter, one of the nation's largest shopping centers, is by far Hawaii's largest black spot, although, I guestimate that most of the reported crashes there are of low severity and the area depicted is of relatively low risk.

One must keep in mind , that high accident spots are not necessarily high risk or high danger spots. As you'd expect, locations with high traffic are also high crash and accident spots. Only if we divide the number of crashes by the amount of traffic occurring in a typical day we can get a better representation of risk.

For example, Location A has recorded 1 crash and gets an average daily traffic (ADT) of 10,000 whereas location B has recorded 8 crashes and gets an average daily traffic (ADT) of 100,000. In this case, B has a higher number of crashes but A has a relatively higher risk for crashes.

Center for Transportation Safety Equity for Rural, Isolated, Tribal and Indigenous Communities

UH-Manoa in collaboration with the universities of Alaska, Idaho and Washington was successful in receiving a 5-year Tier-1 University Transportation Center (UTC) from the U.S. Department of Transportation. Only 36 out of more than 400 proposals were successful.

UH's research budget share is $1.6 million over five years. The focus of the research is on Transportation Safety Equity for Rural, Isolated, Tribal and Indigenous Communities. The principal research investigators are Dr. Guohui Zhang and Dr. Panos Prevedouros.


The purpose of the UTCs is to conduct research that directly supports the priorities of the U.S. DOT to promote the safe, efficient and environmentally sound movement of good and people.  UTCs work with regional, state, local and tribal transportation agencies to help find solutions to challenges that directly impact their communities and affect the efficiency of the nation’s transportation system.
