Scarcity of Engineers in Hawaii

Interviewed by Sara Mattison for the KHON2 story on Pearl Harbor Shipyard competing for qualified candidates.

..."Retirements have disrupted the workforce, but UH Department of Civil Engineering Chair Panos Prevedouros tells us there's a shortage of engineers because of an increase in construction projects. Plus, recruitments from the mainland are not staying.

"Engineers hired from the mainland, they are sort of a revolving door type of problem. They come, they work, but within two three years they feel like mainland is where they belong and that's not very good for local agencies and companies," said Prevedouros.

"We need to compete with cities, counties, and transportation departments on the mainland, and there the pay is much higher in some respects," said Prevedouros."

2016: Caldwell and Hanabusa Agree to Stop Rail at Middle Street.

Back in 2016, Caldwell and Hanabusa were sensible, as quoted in Star Advertiser's Mayor recommends halting the rail route at Middle Street by Marcel Honore.

“I wish we could go all the way to Ala Moana now. That’s for another day,” Mayor Kirk Caldwell told [HART Board].


“It’s not a perfect-world situation,” HART board Chairwoman Colleen Hana­busa said at the Thursday meeting. “But … we don’t have the money.”


Fast forward two years ... Rail is nowhere near Middle Street, yet utility work past Middle Street has been authorized: HART awards $400 million contract to relocate utilities to make way for Honolulu rail

So the fleecing of the taxpayer continues:

"In 2012 HART estimated it would cost about $528 million to build rail’s final four miles. In March it estimated it would cost $866 million. Now [June 2016] it estimates it could cost as much as $1.5 billion to complete that same stretch."

But in May 2018 the utility relocation contract alone is $400M. Can they build a 4 mile bridge with 8 stations, etc. for $1.1B?  I say $3B at least!

‘Complete Streets’ Is Just an Excuse for Government to Spend

My invited commentary in Honolulu Star Advertiser


For decades, traffic engineering meant moving cars. Planners decided that this is wrong and moved the discussion from moving cars to moving people; they said streets are not just for cars, trucks and buses, but also for pedestrians, bicycles, street cars, etc.

However, in the typical medium-to-large American city (i.e., with a metro area population of 1 million to 5 million people,) over 90 percent of the people move in cars and buses, and nearly 100 percent of the goods, move in trucks and cars. Also, in traditional and current traffic engineering practice, the service and safety of pedestrians is top priority.

So what are “Complete Streets” about? They are an excuse for government spending with undesirable economic, environmental and safety consequences, typically presented in the form of neighborhood beautification plans adorned with pleasant descriptions.

Major Driverless Vehicle Faux Pas


In this video the April 2018 Uber/Volvo driverless vehicle accident is analyzed on Israeli TV. The Israel/US (Mobileye/Intel) technology is extolled as superior. Then the superior technology with journalists aboard goes through a red light with schoolgirls about to cross! 

Go to minute 4 and watch the last minute or so of the story. This is a stunning faux pas!

Critical Challenges in Transportation

I received a survey distributed to transportation committees of the National Academy of Engineering on future challenges that will affect transportation. My main responses are as follows.
====================

Please indicate to what extent you are interested in being engaged in activities related to the following critical challenges (not at all interested, not so interested, somewhat interested, very interested and extremely interested).

I was very interested or extremely interested in five out of the 14 critical challenges presented, as shown below along with my rationale.

Changing Characteristics of New Technologies & Innovation Environment (autonomous, shared, data-intensive): Potentially disruptive to traffic and freeway operations because we could get rid of most of roadside/ government data collection and tolling equipment, and rely on the big data generated by Connected Autonomous Vehicles (CAV).

Rapid Entry of Silicon Valley Entrepreneurs in Transportation Technology and Services: We’ve got to watch this one. If the "ITs" succeed in taking over a big chunk of transportation, their next goal will be controlling a big chunk of the government.

Changing Demographics, Values, Preferences, & Behaviors (age distribution disparities, evolving service expectations): Demographics are the most predictable among the future unknowns. But "safety behavior" will become a major challenge as driving progressively becomes a secondary task.

Climate Change (increased disruptive events, concern for sustainability): Major concern for sustainability but due to consumption and resource depletion, less due to climate effects… at least till 2050.

Challenges to Planning and Forecasting (forecasting under rapid change, addressing uncertainties, implementing new methods): 20+ year forecasts are exercises in political appropriation of funds and social engineering. Long term forecasts for facilities and services subject to a lot of possible automation aren't useful.

Uncertainty surrounds $8B Honolulu rail project

National professional news outlet Construction Dive looked into HART in the article Uncertainty surrounds $8B Honolulu rail project after reviewing the Honolulu Civil Beat article What Honolulu Rail Officials Know They Don’t Know.


  • The total cost of the project is in question. Panos Prevedouros, chair of the civil and environmental engineering department at the University of Hawaii at Manoa, estimates that it will cost at least $13* billion. The price tag for the mostly elevated rail line could rise as crews move into the city and navigate unmapped utilities, encounter various types of subsoil, come across potential native burial sites, and possibly damage existing structures as they excavate nearby. In order to provide the public with a rapid rail option and stay within the budget, officials could opt to shorten the system
  • Polls suggest a majority of the public wants to finish rail and stay within the existing budget. Both can be achieved only by finishing rail at the Middle Street Transit Center, where riders can transfer to coordinated options such as pooled ride-hailing and high-tech versions of Honolulu’s award-winning bus service.
  • Prevedouros believes such a plan would give taxpayers substantial value for their money already spent on rail, by getting people beyond both the H-1 and H-2 and the Middle Street merges while avoiding untold billions in construction costs and freeing up any saved construction financing to pay for operations and maintenance.
  • Most rail commuters will need to transfer at least once in any event. Consider this example: If rail were built to Ala Moana Center, it would take 12 minutes to get there from Middle Street by rail, and then another 16 minutes by bus to University of Hawaii Manoa — a total of 28 minutes. But if rail terminates at Middle Street, a UH student can get to Manoa by express bus in about 20 minutes.
-------------------------

(*) Back in 2009, FTA's consultant Jacobs of Dallas, TX conducted a risk analysis on HART's budget (actually Honolulu rail became the HART project after 2010) and showed a 10% chance of the project costing $10.5 billion. During the Legislative session of spring 2017, Mayor Caldwell mentioned that for all practical purposes the cost of the project is $10 billion. See "Mayor Kirk Caldwell and City Council Chairman Ron Menor think Oahu taxpayers are so rich we can pay not only for a $10 billion rail system that’s $5 billion over budget and climbing, but also for road projects on the neighbor islands."

As of 2018, the project is at least 6 years late (and likely to have further schedule slippages).
  • Taking the Jacobs $10.5 B projection and compounding it by 4% over 6 years gives a year of expenditure (YoE) cost of $13.29 Billion.
  • Taking the Mayor's $10.0 B projection and compounding it by 5% over 6 years gives a YoE cost of $13.40 Billion.
  • If you dislike compounding inflation and prefer the simple inflation of costs, then the corresponding numbers are $13.02 B and $13.00 B.

The Onion on Transportation

Satirical publication The Onion has at least three priceless articles on transportation, as follows:


  • November 29, 2000, Report: 98 Percent Of U.S. Commuters Favor Public Transportation For Others

WASHINGTON, DC–A study released Monday by the American Public Transportation Association reveals that 98 percent of Americans support the use of mass transit by others.
...
Anaheim, CA, resident Lance Holland, who drives 80 miles a day to his job in downtown Los Angeles, was among the proponents of public transit.

"Expanding mass transit isn't just a good idea, it's a necessity," Holland said. "My drive to work is unbelievable. I spend more than two hours stuck in 12 lanes of traffic. It's about time somebody did something to get some of these other cars off the road."

Public support for mass transit will naturally lead to its expansion and improvement, Los Angeles County Metropolitan Transportation Authority officials said.

"With everyone behind it, we'll be able to expand bus routes, create park-and-ride programs, and build entire new Metrolink commuter-rail lines," LACMTA president Howard Sager said. "It's almost a shame I don't know anyone who will be using these new services." READ MORE


  • March 10, 2004, Urban Planner Stuck In Traffic Of Own Design

PITTSBURGH, PA—Bernard Rothstein, an urban planner and traffic-flow modulation specialist with the Urban Redevelopment Authority, found himself stuck in rush-hour traffic of his own design for more than an hour Monday.
...
As Pittsburgh, America's steel capital, made the transition to high-tech and service industries in the 1980s, many thought its rusting, blighted urban landscape was obsolete. According to Rothstein, it was then that the Urban Redevelopment Authority, along with several private urban-planning firms, began the slow process of rethinking the city's roads, parks, and commercial and residential districts. Today, the city's designers are regularly lauded for their elegant, modern buildings and stuck in traffic of their own making for hours at a time. READ MORE


  • February 5, 2018, MTA Reminds New Yorkers They Can Fucking Walk

NEW YORK—In response to numerous complaints regarding recent delays and route changes to the city’s public transportation system, Metropolitan Transportation Authority officials at a press conference Monday reminded residents that they can fucking walk. “While we always do our best to avoid inconveniencing our customers, city residents should be aware that at any time, they are more than welcome to get off their asses and use their two fucking feet to reach destinations,” said MTA spokesperson Reggie Dawes, adding that the city’s comprehensive street grid system is easily accessible on foot ...

Ban the Bike! How Cities Made a Huge Mistake in Promoting Cycling

Summary by Robert Poole of Lawrence Solomon's article. Solomon is an environmentalist whose career with Canada’s Energy Probe Research Foundation spans several decades.


"  Expanding the role of bicycle travel in urban areas has been government policy in developed nations for several decades. As Lawrence Solomon wrote in a recent piece in Canada’s Financial Post, “At no expense to taxpayers, the bicycle took cars off the road, easing traffic; it saved wear and tear on the roads, easing municipal budgets; it reduced auto emissions easing air pollution; it reduced the need for automobile parking, increasing the efficiency of land use; and it helped keep people fit, too.”

Yet despite these ostensible benefits, something of a “bikelash” is under way, in cities that include Amsterdam, several major cities in China, London, Singapore, and elsewhere. As The Economist reported in “The Bikes That Broke Free” (Dec. 23, 2017), one emerging problem is dockless bike-sharing systems that have plagued cities with bikes left all over the place. Amsterdam has banned such systems, and a growing number of Chinese cities have called a halt to any expansion of existing systems.

Solomon—once a strong advocate of urban bicycling—has concluded that bicycling today “is a mixed bag, usually with more negatives than positives. In many cities, bike lanes now consume more road space than they free up; they add to pollution as well as reducing it; they hurt neighborhoods and business districts alike; and they have become a drain on the public purse.”

Many of his examples come from Europe and Australia, where cities have been far more aggressive in promoting bicycle use than is typical in the United States. Transport for London has spent large sums to create a “cycle super highway” that has taken away traffic lanes and increased traffic congestion, sparking a significant backlash. Paris is spending €150 million on cycling infrastructure, Amsterdam €120 million just on bike parking spots, and Melbourne is under way on a $100 million cycling plan.

Negative health impacts are an unexpected consequence of aggressively expanded urban bicycling, Solomon notes. Congestion caused by taking away traffic lanes leads to idling traffic, which increases emissions. Cyclists are the most-exposed to PM2.5 soot from idling vehicles. A study by the London School of Medicine found that cyclists in London have 2.3 times more inhaled soot than walkers, because “cyclists breathe more deeply and at a quicker rate than pedestrians while in closer proximity to exhaust fumes.”

Although Solomon doesn’t mention cyclist deaths and injuries due to driving in close proximity to motor vehicles, my traffic engineer friends tell me (off the record) that they are appalled by the proliferation of bike lanes on major U.S. arterials that, because they are a vital supplement to the freeway system, increasingly have traffic signal timing aimed at providing rolling green lights and 40-45 mph speeds. They would much prefer that bicycles be kept away from such high-volume traffic arteries.

Solomon also points to concerns of local merchants who depend on metered street parking for their customers. In some cities, bike lanes have replaced street parking. The result is to replace a multi-function lane (traffic lane during AM and PM peaks, parking and truck delivery space at other hours) with “a single-function piece of under-used pavement.” Cities lose the former parking meter revenue, and in some cases have to build expensive parking structures nearby to replace the street parking.  "

Honolulu Rail Creates One Tenth of Jobs Promissed

Quoted in Marcel Honore's article in the Honolulu Civil Beat Rail Promised Lots Of Jobs But There’s No Sure Count Of What It’s Delivering.
  • “It’s not the kind of project that lends itself to a huge amount of workers working at the same time,” said Panos Prevedouros, a longtime rail critic and one-time mayoral candidate who chairs the University of Hawaii’s Civil Engineering Department. “The way they did it, it’s much simpler to manage. It takes a longer time, but it keeps the (job) count quite low.”
By "the way they did it," I explained to Marcel that HART rail is being built one segment at a time by a single builder, instead of having, say 4 builders building 5 miles each, simultaneously.

  • Prevedouros said the city should keep better track of the actual jobs that rail is generating since that was such a strong part of the pitch years earlier to build the project.  “What was presented and promised, it was all rhetoric around the Great Recession we had. So it was a big selling point,” he said.  “Really, 1,000 jobs doesn’t make or break anything.” [in Honolulu]
It wasn't difficult for me and unbiased economists to see the lies in the jobs numbers. Back on April 14, 2010, I exposed this in my article Proposed Rail Creates 1,000 Local Jobs and Destroys 4,000 Jobs.

See Scott Ishikawa serving city propaganda for the 10,000 jobs... and an interesting comment underneath.

On March 23, 2012 I simply wrote that HART's Job Estimates Are Wrong.

So, let's recap... So far I was right about the cost of rail will be much higher than advertised, the delivery of rail would be much longer than advertised, and that the advertised job numbers were fake.  There are two big ones left: Reliability and Ridership.

Reliability may be better that mediocre now that Hitachi has put its name on the Ansaldo trains. Ridership will be, at best, one half of what the city proclaimed in the EIS (see my estimate.)

Behaviour of Lithium-Ion Batteries in Electric Vehicles


Hot off the press and pleased to be coauthor of Chapter 5 of the newest book on lithium batteries for transportation. I co-authored this article with my 2011 PhD student Dr. Lambrosw Mitropoulos.

Our chapter is titled Conventional, Battery-Powered, and Other Alternative Fuel Vehicles: Sustainability Assessment.

ABSTRACT:   The substantial impacts of transportation on environment, society, and economy strongly urge the incorporation of sustainability into transportation planning. Major developments that enhance transportation sustainability include alternative fuels, electric drive and other novel technologies for vehicle propulsion. This chapter presents a sustainability framework that enables the assessment of transportation vehicle characteristics. Identified indicators are grouped into five sustainability dimensions (environment, technology, energy, economy, and users). The method joins life cycle impacts and a set of quantified indicators to assess the sustainability performance of seven popular light-duty vehicles and two types of transit buses. The hybrid diesel electric bus received the highest sustainability index and the internal combustion engine vehicle the lowest. Fuel cell and hybrid electric vehicles were found to have the highest sustainability index among all passenger vehicles. The sustainability performance of some new technologies currently suffers from limitations in engine and battery performance, comfort and convenience, and availability of charging stations.

26 UH Engineering Undergrads Achieve Professional Certification

More than two dozen students in the civil and environmental engineering program (CEE) at the University of Hawaiʻi at Mānoa became Envision Sustainability Professionals (ENV SPs) before the end of the fall 2017 semester.

All the students were enrolled in the College of Engineering‘s CEE 444 course on infrastructure sustainability.
To become ENV SPs, they passed a comprehensive assessment of sustainability credits that are applicable to any type of infrastructure project, including new projects and expansion or rehabilitation projects.
The exam was developed at Princeton University and is administered by the Institute for Sustainable Infrastructure.
Encouraged by discussions at the National Civil Engineering Department Heads Conference last summer, Civil Engineering Professor Panos Prevedouros contacted local ENV SP engineer Jon Young and Leadership in Energy and Environmental Design engineer Amber Takenouchi about presenting lectures to his CEE 444 students.
Both had facilitated an envision course in February and were willing to help. They created a 40-question homework assignment and, with Prevedouros, prepared and presented three lectures.
The students were given a choice. If they took the envision exam and passed it by December 12, it would stand in for their final exam. Prevedouros emphasized to the students that this would be a personal decision to build up their own records and not a course requirement (the final exam is 30 percent of the grade in CEE 444).
Nearly all of the students chose to take the exam. Prevedouros was ecstatic at the results.
“I thought that this addition to the course would have been a small success if about a dozen students tried the exam and maybe half of them passed it,” he said. “It would have been a clear success if just ten passed, but 26 of our undergraduates now have a professional certification before they actually have their degrees.”

[Originally posted by University of Hawaii: 26 UH engineering undergrads achieve professional certification, on December 27, 2017.]

Hawaii Wakes Up to Fake Missile Attack


Hawaii suffers from government unions which are the institutionalized protection (if not cultivation) of incompetence, laziness and un-accountability. These unions have become so big and powerful that most of the time succeed in electing politicians of their choosing, and control them to their liking. All this dysfunction lead to today's international embarrassment of the fake ballistic missile attack.

This must not be another day in paradise. Heads should roll. Preferably 38, one for each minute of absurdly incompetent failure to recall the alarm.

It’s Not Too Late to Build Rail Better

Quoted in Honolulu Civil Beat's editorial board opinion about HART.

Honolulu’s prophets of doom for the rail project — Randall Roth, Cliff Slater and Panos Prevedouros — believe they were right all along that the city’s ambitious mass-transit plan is a mess.
...

Roth, Slater and Prevedouros have imagined exactly that. And that is why they’ve accepted the reality that rail is “happening,” as Prevedouros put it in a recent editorial board meeting with Civil Beat. It comes in the wake of the Hawaii Legislature approving a $2.4 billion funding package to continue building the rail line, now pegged at $8.17 billion.

What Roth and Co. are are not accepting, however, is that the city and the Honolulu Authority for Rapid Transportation should go ahead and build all of the planned 20 miles and 21 stations. Instead, they want rail to stop at Middle Street.
...

But what Roth, Slater and Prevedouros argue now is that, because Middle Street is home to Oahu Transit Services — home of TheBus, The Handi-Van and the Kalihi-Palama Bus — it can be the future of what they envision as a multimodal hub.


What’s central to this thesis is that transportation technologies and business models are developing faster than once thought possible. Ride-hailing companies like Uber and Lyft have altered the way consumers view short trips, while automated buses and cars are already being tested and deployed.
...

Roth and Co. believe the FTA would be open to a new plan. The built guideway could eventually be modified to accommodate shared or automatic transportation systems.
