Honolulu Traffic Lights: 12 Minutes for One Half Mile in Waikiki!


On Good Friday I had the opportunity to observe the typical gridlock traffic conditions of a busy Friday in Waikiki.  Then I found a perfect object to monitor.  An articulated (bendy) city bus with the number 154 stencilled on its roof. I tracked it as it motored along on Kalia Street, made a left turn onto Saratoga Street and eventually crossed Kalakaua Avenue and disappeared from my view.




The total distance from the Hale Koa hotel to Kalakaua Avenue is 0.55 miles.  An acceptable speed for buses is 7 miles per hour including stops so this distance would have taken 4.7 minutes.

Bus 154 took 6 minutes to reach Saratoga at an average speed of 3 mph, and took another 6.5 minutes to cross Kalakaua Avenue at an average speed of 2.3 mph which is much slower than walking speed for most people (3.1 mph according to Google.)

Fantastically, a day earlier I get a call from KHON2 News. They wanted my opinion on the city's
new multimillion dollar proposal to synchronize its traffic lights.  So I marvel at the fact that instantly upon getting elected to City Council, Stanley Chang knew that rail will be Oahu's savior for traffic congestion.  (I met him and he told me that.) Yet it took Stanley three years and a candidacy for U.S. Congress to figure out that Honolulu's traffic signals work poorly and now he wants to fix all of them at once with a five million dollar study!

Ineffective hyperbola rules the day in Honolulu. A day before the traffic project announcement, the president of HART promised to deliver 10 miles of elevated rail with ten stations and operating trains 36 months from April 2014.  I'll bet him $36,000 that this is NOT possible!

What can I say?  We certainly need more lawyers like Kirk Caldwell (Mayor), Stanley Chang (City Council), Ivan Lui-Kwan (HART president) and Mike Formby (City Transportation Director) in charge of Oahu traffic and mobility. All blah-blah and promises while traffic and buses crawl at 3 miles per hour.

"Modern" Light Rail: Worth the Investment?

The answer comes quickly in the introduction of this well-researched article in The Atlantic Cities: No!


  • Five U.S. metros (Buffalo, Portland, Sacramento, San Diego, and San Jose) opened light rail systems in the 1980s to great fanfare. 
  • Portland became transportation models for the country, pointing toward a transit-friendly urban future.
  • Based on the decisions to build these projects, which were made by hundreds of local officials and often endorsed by residents through referenda, you might think that the experience building light rail in the 1980s had been unambiguously successful. 
  • Yet it doesn't take much digging to find that over the past thirty years, these initial five systems in themselves neither rescued the center cities of their respective regions nor resulted in higher transit use — the dual goals of those first-generation lines.
  • According to an analysis of Census data, in four of the five cities with new light rail lines, the share of regional workers choosing to ride transit to work declined.

U.S. Infrastructure Projects Cost Way More Than They Should, Explained

The Atlantic Cities magazine published a condensed analysis of seven main reasons that explain why U.S infrastructure project cost more than elsewhere. They are:

 1. Davis-Bacon Laws: Passed in 1931, the Davis-Bacon Act mandates that laborers for federal public works projects receive local prevailing wages. (+22%)

2. Project Labor Agreements: In 2009, President Obama signed an executive order mandating that contractors for federal projects exceeding $25 million sign Project Labor Agreements, which guarantee the hiring of union workers. (+13~15%)

3. 'Buy America' Provision: For decades, this provision has discouraged projects from being built with manufactured goods made outside the U.S. Obama strengthened it in the 2009 stimulus package to include projects besides just highways. (+10~500%)*

4. Lengthy Environmental Reviews. (+10~25%)*

5. Transportation Alternatives Program: Everyone can agree that walking trails, complete streets, historic renovations, landscaping, and bike lanes are public goods, but should they be paid for with highway fund money? This is the current policy of the FHWA. (+5~20%)*

6. Administrative Costs: Currently, U.S. transportation revenue is like a boomerang, going from the states to Washington and back. Naturally, this process adds bureaucratic costs. (+10%)*

7. Toll Bans: Although tolls exist along some stretches of interstate, they are generally not permitted by the federal government. This has stripped the government of a key revenue source that could be used for repairs, and for cheaper borrowing. (+10~50%)*

2010-2013 U.S. Metropolitan Area Changes

This domestic migration three year snapshot indicates that Americans are moving out of Democrat, cold and mismanaged cities with expensive transit systems to Republican, warm and business-friendly cities with small or medium transit systems.  Smart!

Hawaii's Electric Company Suffers National Humiliation (Forbes)

On September 6, 2013 Hawaiian Electric Company or HECO changed the rules for connecting solar systems. Based on DBEDT data, the number of residential permits in December 2012 were 2,452.  With the new rules in effect, the number of residential permits in December 2013 were 1,218, a 50.3% reduction.

FORBES:  A Hawaiian utility has tried to slow the growth of solar. In December, Hawaiian Electric Company shut down rooftop solar installations, citing “grid stability.”

“That’s another bullshit argument,” said Chu, a Nobel Prize winning physicist who served as energy secretary from 2009 to April, 2013. Solar installations don’t threaten grid stability until they approach 20% of the customer base, Chu said. In Hawaii solar is at 2%.

(Hawaiian Electric disputes Chu’s 2% figure, and spokeswoman Lynn Unemori says the company has not halted solar installations, but has adopted “a more cautious approach to applications for new PV systems on circuits with a large amount of PV already installed, solely for reasons of safety and reliability.” ) END QUOTE


But Roy Skaggs of Alternate Energy, Inc. won't let Lynn's "word-smithed" response stand:

Lynne,

To quote Mr. Chu above, that’s a bullshit response. The only thing I agree with you on, is that rooftop solar has exceeded 2%. The rest of your canned response is the same vomit regurgitated by Scott Seu and sadly what we have been sometimes even seeing from the PUC. HECO has blocked many people, including ones who you were supposed to grandfather. This “approving new installations daily” statement is so exaggerated that you would have to work for HECO to believe it. But hey, I guess if you approve 1 installation a day and block 20, then you can get away with that line!

How can you say HECO “strongly supports” PV? Since September, the entire industry has been cast away by HECO. How many hundreds of lost jobs and millions of dollars does it take before HECO admits they do not support anything but their own profit margins? You have hundreds of customers stuck in limbo for months who signed contracts and committed to PV before Sept 6th, and HECO has still not resolved those poor families troubles. Many are paying bank loans AND HECO!

And let’s talk for a second about this “grid saturation” that HECO holds onto and tries to pass off as truth. Scott Seu admitted in front of Senators and Representatives in October that there are grids over 200% DML. Where are the voltage spikes of record? Surely, with such “unsafe” levels, HECO would have examples to provide, right? The newest delay HECO is pushing is something already in place. The inverters being used by most, if not every single company, have protection in place from the bogus claims of “voltage spikes” that HECO has been spewing. These fast trip invereters are there and have been there. So why are solar companies just now getting word to provide proof that the inverters do indeed have this in place? We have been telling you they do for months.

What is HECO’s next delay tactic? The jig is up. More and more news outlets and industry professionals, like Mr. Chu, are calling you on your bullshit. If HECO doesn’t work with solar and the customers who want it, you will soon go the way of the land line.

How can a monopoly tell hard working Americans that they cannot capture the free sun on their own rooftops? You can’t. This is a losing battle for HECO. Innovate or go extinct.

HECO's Renewable Watch

Hawaiian Electric Company (HECO) has launched a website which displays in near real time the generation of electric power on each Hawaiian island by solar (photovoltaic or PV) and wind renewable energy: Renewable Watch.

Shown below is the image for the Island of Oahu caught at the time of this post...


At this instance at 11:54 AM, solar PV is making 142 MW whereas wind is making 58 MW.

Bicycling Safety Through the Eyes of TOP GEAR

TOP GEAR is an internationally syndicated car show of the BBC.  They specialize in both admiring and mocking all forms of transportation, with an emphasis on (super)cars.


In March 2014 they aired their "serious" TV adverts, as they call them, in response to calls by the City of London to improve bicycle safety.

You can search the web for the "outrage" the TOP GEAR TV ads caused.  Here is a sample from The Oregonian.

They are funny and they do have a bit of a point as well.  Enjoy the TOP GEAR YouTube threesome:

Driverless Cars? Yes, GoogleCar, iCar, etc. are Closer than they Appear


No need for a driver's license?

Will the blind drive? 

Is this the end of accidents and insurance payments?

Will a multilingual automated car replace the taxi and handi-van?

Well, not so fast. Driverless cars are a Pandora's box of opportunities and challenges. One thing is for certain: They are coming.  First in simple versions; later on, in completely automated versions.

For example, Audi, BMW, Cadillac, Nissan and VW plan to offer 2016 model year cars that do at least half of these: braking and  throttle control (e.g., Delphi adaptive cruise control), self driving in stop-and-go traffic (e.g., BMW's traffic jam assistant), lane keeping (e.g., Toyota's lane keeping assist), gear shifting, and, if legal, unoccupied self-parking after all occupants and the driver exit the car (e.g., Audi's parking demonstration.)

Goggle has developed ten Google Driverless Cars (see sample photo) that have clocked well over 300,000 miles on California roads with only two reported accidents: One when the car was read-ended at a stop light and another near Google headquarters while driven by a person.  Google has produced a short video that shows a man driving around, picking up some food at a drive through store and arriving at home, opening his door and then extending his blind person cane to find his way to his house! Google expects sales of regular cars modified by Goggle to be drivereless in 2018. (Take a look at this CNN infographic.)


These developments cannot come soon enough because US, European, Chinese and other developing world cities are chocking in traffic.  Driverless cars will be a large part of the solution. They can follow each other at a distance of 0.5 seconds (engineers call this “headway”) instead of the average human headway of 1.5 seconds. This difference from 1.5 to 0.5 seconds of headway triples the capacity of a freeway lane from 2,200 vehicles per hour to over 6,000 vehicles per hour.

Sometime between 2030 and 2040, drivereless cars will become prevalent with more than one third of them in traffic. Then selected highways and arterial streets can be converted to driverless car highways with 8 ft. wide instead of 12 ft. wide lanes because driverless cars can adhere to a tight lane discipline.

The combination of tight lanes and close headways will have huge impacts to roadway capacity. Today two lanes on the Pali Highway have a capacity of roughly 4,500 cars per hour.  With only driverless cars on them the capacity of the same exact roadbed would be about 20,000 cars per hour. More than four times improvement; this will result in continuous 50 mph traffic flow. No congestion.

The driverless car technological innovation cannot come soon enough. For all but four U.S. cities (Chicago, New York, San Francisco and Washington, D.C.) city transportation is done in private cars, vans and trucks 85% of the time or more. Telecommuting has already surpassed the share of trips by transit. Car-sharing, and intelligent, drivereless zero emission vehicles will maintain the car’s dominance here and abroad.

But before completely driverless car become ubiquitous, self parking cars will arrive.This will have a huge impact for complete parking lots because now a couple feet of clearance is required between cars for driver access.  The self-park cars will only need a couple of inches of clearance between their folded exterior mirrors. So the large parking structure at the University of Hawaii holding about 5,000 can easily store 6,000 much to the improved convenience of students and a few hundred thousand more dollars of revenue for the UH.

Recently there were rumors that a Tesla Cars-Apple Computer "affair" may be about a future (autonomous) iCar.

I have little doubt that thirty years from now my kindergartener son and his friends will be commuting in driverless electric sports cars that can reach 0-60 mph in 5 seconds, follow at a headway of under 0.5 seconds on narrow high capacity lanes, be a full office away from home or work, and still deliver an exciting drive in off-drivereless mode outside the city.  The future of transportation in the U.S. will be great as long as it does not invest on modes of the past millennium such bicycles and ordinary trains, except for limited applications where they may be both practical and cost-effective.

A shorter version of this article was originally published on February 15, 2014 in Hawaii's Filipino Chronicle.

"Get People Out of Cars" vs. Drivereless Cars

My opinion printed on pages 10 of the March 2014 issue of the ITE Journal.

Mr. Schwartz’s call for making the transportation engineer relevant is important. Sharing this realization, I ran twice for Mayor of Honolulu on an infrastructure preservation and traffic congestion relief platform and I garnered almost 20% in both 2008 and 2010.  Mr. Schwartz' advise to transportation engineers is good except for his instruction to “get people out of cars.” New York City may boast that 70% of commutes occur on non-auto modes, but it’s an exception. The next U.S. city with a low auto-mode share barely has 30% of commutes occurring on non-auto modes. Telecommuting is surpassing transit. Car-sharing, and intelligent and autonomous zero emission vehicles will maintain the auto mode’s dominance.

In 30 years or so, my kindergartener son and his cohorts will be commuting in driverless electric cars that can reach 0-60 mph in 5 seconds, follow at a headway of under 0.5 seconds on narrow high capacity lanes (some four lane urban highways will convert to automated guideways with six 8 ft. lanes), be a full office away from home or work, and still be exciting to drive in off-drivereless mode outside the city.  The future of transportation engineering in the U.S. will be great as long as we do not expend substantial resources on modes of the past millennium such bicycles and ordinary trains, except for limited applications where they may be both practical and cost-effective.
