A Public Intellectual of Hawaii: Panos Prevedouros

A conversation with Dr. Keli'i Akina, president of the Grassroot Institute, about traffic congestion, Honolulu rail and Hawaii's renewable energy plans.

Taped for an hourly show for Think Tech on channel OC16.

Kapolei should have never happened

In her article titled Kapolei Hale turns 15 and the accompanying video Kapolei: Oahu's Second City?, reporter Jayna Omaye and videographer Kimberly Yuen present the story of Kapolei which, starting in 1990, took pure agricultural or unimproved land and began changing it into a "second city."

“Kapolei is a planning disaster,” said Panos Prevedouros, a civil engineer who has taught at UH for 25 years and specializes in transportation engineering and infrastructure sustainability. “It’s a bedroom community. It didn’t develop into a Second City. It developed as pure mainland-style suburbia.”

Prevedouros said traffic congestion and the lack of infrastructure and jobs point to Kapolei continuing on the path to become “Anywhere, USA.”

George Atta, DPP director, said Kapolei should have been developed with higher densities and in clusters, adding that building heights are 150 feet. Kapolei should grow in nodes, with each having its own characteristics and that should eventually connect — similar to downtown Honolulu and its Ala Moana, Kakaako and Waikiki neighborhoods, he said.

Kapolei should have never happened.  Honolulu should have developed into a dense urban strip from Salt Lake to Waikiki, a 10 mile corridor. In it mass transit would have succeeded with a compact high capacity, partially underground rail line.  But the powers that be and the planners who serve them opted for a double disaster. Kapolei's suburban sprawl 20 miles away from the city and an expensive, elevated rail system to permanently tether the second city to the first.  Bad plans lead to bad solutions and high costs.  And that's all we are reaping.

Why Could Driverless Cars Fizzle Out?

I have been collecting materials to compose a "contrarian article" to the hype about driverless vehicles.  I should be clear that I support driverless technologies but I am skeptical of fully autonomous, driverless vehicles.

I believe that many more components to automate driving will be added to the existing adaptive cruise control available to several mid-range and most luxury vehicles. These technologies improve both comfort and safety and they are quite readily accepted by the vehicle owners and users. For example the loaded version of the new Toyota Prius will have automated lane keeping and car following. (See Toyota's extensive list of automated driver support systems.)

Fully automated pods, cars, trucks and buses is another story, as explained in Why Driverless Cars Will Screech to a Halt.

The article may be off putting with remarks like .... "It’s clear that Uber and some of the other companies are professional carnival barkers engaged in an amazingly brash self-driving con."

However, it is spot on for huge issues like this... "But here is where we have to stop for a moment and think a bit more deeply about the unfolding plot of this science-fiction movie. Approximately 1.6 million Americans are truck drivers, and their jobs are on the hockey-mask-wearing villain’s chopping block. Is it really all that “efficient” to unleash a technology that will wipe out all these jobs? Isn’t it also efficient for people to have gainful employment?"

Remember, when it comes to politics... "it's the economy, stupid"... is the bottom line.  Killing off millions of bus, truck and taxi driver jobs is a vastly unattractive proposition.
