Factors that Explain Honolulu's High Pedestrian Accident Rate

Honolulu has a high number of pedestrian accidents. There are several factors at play. If properly adjusted, Hawaii's pedestrian accident rate is moderate.

1. Weather. Hawaii provides comfortable walking conditions year round.  That's not true for many other US urban areas. Many are too cold, e.g., Chicago and New York City, or too hot, e.g, Phoenix, and Houston.  Because of these conditions Honolulu pedestrians have many more opportunities, maybe more than twice the opportunities of Phoenix or Minneapolis pedestrians to get into accidents. However, national accident rates are not adjusted for this, nor for walkability.

2. Walkability. Honolulu historically has been a walkable community as it draws from Asian culture. Most other US cities developed more around the horse-and-buggy and later the car. Many US cities have skyways and underground pedestrian ways that eliminate traffic/pedestrian interactions. Honolulu's higher walkability comes with a higher risk for pedestrian accidents, particularly nowadays when many people connect to the digital world and partly depart from the real one.

3. Aging.  Compared to many other US cities of about one million people, Honolulu has a higher percentage of old people.  Unfortunately I have witnessed several of them making risky crossings. The city has removed several pedestrian crossings and has added crossing signals at high pedestrian volume locations.

4. DUI.  This is one area where Hawaii takes the lead in the nation (see Figure below).  Drug or alcohol impairment affects both drivers and pedestrians.  Poor judgement under the influence of substances greatly increases risk for all types of accidents, including pedestrian accidents.

5. Busy highways next to popular beach and surf spots.  Hawaii clearly needs some bypass roads in such areas because of the unsafe mix of heavy through traffic, multiple parking maneuvers and disorganized pedestrian crossings, e.g, Turtle Beach and several other spots statewide.

While Hawaii is shown to have the 4th worst pedestrian accident rate in the nation, if the data are properly adjusted, Hawaii's pedestrian accident record will be average.  Some of the reasons above also apply to bicycle and motorcycle accidents.  However, there are no reasons to adjust and excuse Hawaii's worst in the nation for DUI.

2014 American Community Survey: Honolulu Mode Shares

Transportation modes are the means by which people move around in a city, particularly for their commute to work. The mode shares for "Urban Honolulu, HI Urbanized Area (2010)" are listed in Table B08301 of the 2014 American Community Survey. They are as follows:

The same data in pie chart form:

There are several important observations:
  • Personal transportation (cars, bikes and motorcycles) is used for 80% of the trips.
  • Bicycling in Honolulu is only 1.1% of the trips.
  • Work at home is a welcome 3% of the trips, similar to the US average.
  • Walk is over 5%, which is better than the US average.
  • Public transit (bus and taxi) is almost 10%, which is much better than the US average.
Almost 90% of the trips shown require roads and another 8.4% of the trips shown do not require substantial infrastructure (just sidewalks and the Internet.)

So how does the state, city and OMPO address the people's preferred use of transportation?  They provide an obscenely expensive elevated rail alternative that saps transportation funds for much needed road and sidewalk repair and expansion.


Rail Projects: Excerpts from a National Discussion

Last week one of my students asked why rail projects don't get stopped. The following quotes are from recent discussions with national leaders in transportation, regarding the  proposed $2 billion Purple Line for the Washington Metro.  Notice that their quotes are as if they are talking about Honolulu rail... [My comments]

1   One thing that always has to be remembered is that no FTA staffer, or FTA as an institution, is EVER going to take credit for killing a project – and, when it comes down to a GS-12 vs. a Congressperson on a project going forward, who do you think is going to win in the end?" [In Honolulu' s case, Senator Inouye had 40 years of congressional seniority,  i.e., he was unstoppable.]

2  This is what has become of urban transit planning: US Senators playing the role of God in disbursing --or threatening the loss of-- oodles of tax money.  Every FFGA now must come with the Good Housekeeping seal of approval of the state's senior Senator. Alternatives analysis, schmalternatives analysis.*  Its just good old-fashioned pork.  The Senate doesn't work. (* the AA in Seattle for light rail was a sham.) [So was Honolulu's AA that eliminated the PH tunnel with a couple lines of discussion.]

3  It's all about getting elected and staying elected until they die. When they get money for a local goodie, they tell their constituents that its free money just for them.  The other thing they say to the folks back home is that they create jobs but those jobs are mostly for workers from somewhere else. [No comment is necessary.]

4  One thing that you have to understand about building rail lines, most particularly those in urban areas, is that speed is not really a high criterion, particularly compared to the need to keep costs down.  Now, when I say, “keep costs down” in a discussion of urban rail lines, the first reaction of many people is to say, you have got to be kidding, this is not a priority at all – and you cite the $200 million/mile for the Portland Orange MAX line. Urban rail costs have become unbelievably high. When I was working on the Long Beach-Los Angeles light rail Blue Line in the 1980’s, it was coming in at about $877 million (actual cost was over $1 billion, but this wasn’t really known at the time, and it certainly wasn’t publicized) [This is why Honolulu will be "lucky" if the cost per mile stops at $500M, that is, the $4.6 billion Honolulu rail will have an actual cost of $10 billion.]

Honolulu's Recycling Plan Needs Important Revisions

Throughout my campaigns for mayor of Honolulu I focused on the flawed recycling efforts of Honolulu. Huge amounts of effort and fuel are wasted to recycle things instead of safely burning them and making free electricity for Honolulu.

Back in 2013 I developed a pictorial guide for Honolulu.

Later in 2013, a graduate student of mine and I published an article in the Pacific Business News which revealed that "Waste to energy is superior to any other technology in the long term."

Then in July 2015 HONOLULU magazine quotes me about a dozen times in their detailed article Should Honolulu’s Recycling Program Go Up in Flames?


“Trash is treasure,” says Panos Prevedouros, chair of the Department of Civil and Environmental Engineering at UH Mānoa and a former mayoral candidate. “Not only do you make energy, you remove something that is bad.” Prevedouros adds that a waste-to-energy plant can make “serious money” charging tipping fees, selling its electricity to the utility and harvesting the valuable metals for what he calls “a win-win-win” situation: The plant helps the state meet its renewable energy goals...

Paper and cardboard are heavy and hard to compact further for efficient shipping to recycling plants; they burn beautifully, and are depressed in price. “Paper, oh, my God, it’s really perverse to recycle. We’re losing the opportunity to make energy, and we’re wasting more fossil fuel to ship it somewhere else. If you have paper, put it in the gray bin,” says Prevedouros.

Driving Automation ... Sooner?

Automatic Cars Or Distracted Drivers: We Need Automation Sooner, Not Later argues professor Don Norman.  Technology is moving that way. It's not a matter of if, it's a matter of when.

In 2005 Stanford's "Stanley" a driverless VW SUV won the DARPA award for negotiating a grueling 132 mile off-road race in the California/Devada desert.

By 2010 Google had several driverless Prius cars plowing streets in California practically accident free.

In 2015 the Google car is unveiled with no steering wheel and a top speed of 25 mph.

When will the ability of driverless vehicles meet and exceed the ability of drivers? Driver distraction and age effects are helping technology by raising risk which is better controlled in driverless cars.

Driverless Cars: Does Google Have Answers?

Lou Frenzel who writes and teaches about electronics and communications recently opined Just Say No to the Driverless Car. His article includes 15 questions and the 16th one is Does Google Have Answers?

I have an answer for Google, but first, Frenzel's 15 questions for driverless cars:

  • Can driverless cars operate as safely at night as they do during the day?
  • Can driverless cars handle rain, fog, and snow?
  • Once a driverless car gets you to your destination, can it find a parking place in a parking garage or on the street? Can it navigate your garage?
  • What if you want to go for a casual Sunday drive with no particular destination? Does the car have a “browser” that lets it just wander in a highlighted area, or what? Or will that even be allowed?
  • Will drivers get frustrated in navigating around slower, more-cautious driverless cars?
  • Can a driverless car ever make a left-hand turn across traffic, make a right turn on red, or merge into heavy traffic? In many cases, some risk is necessary to make any progress.
  • Can a driverless car find a toll lane, navigate road construction, or find a detour?
  • Can a driverless car operate in New York City traffic?
  • Will the driverless car really improve a person’s productivity if relieved of driving duties, as proponents claim?
  • Will there be an increase in the incidence of motion sickness in non-drivers, as some expect?
  • Whose insurance company pays in case of an accident?
  • Will driverless cars really reduce deaths and injuries? Supporters say yes, but this has not been proven.
  • Will driverless technology come to 18-wheelers? Scary thought.
  • Will driverless cars really be affordable, or just too expensive like electrics?
  • Why not just apply all the good technology to regular cars or make a driverless mode an option?

  • The last three questions are easy to answer.
    18-wheelers? Yes, for testing purposes: Daimler’s Driverless 18-Wheelers Approved to Cruise Nevada’s Highways
    Affordable? No. Driverless cars: 15 things you need to know. System costs start at $70,000 (plus the car.)
    Optional driverless function? Yes. It has started with intelligent cruise control, lane keeping, and other piece-meal components available now in mid-range priced vehicles and above.

    So, does Google have answers to all these questions? Google rarely published or debates the merits and demerits of their current state of the art.  My guestimate is Yes, a Google Car can do all of the above with over 99% reliability if, and it's a big if, all traffic is limited to 30 mph or less.
