Interesting and Somewhat Contrarian Covid-19 Data

• The picture above circulates on Twitter but the URL for the CDC website does not match what is shown. If the data are correct, they suggest fewer deaths from pneumonia since November 2019 because more deaths were likely attributed to Covid-19.

• The Curve is Already Flat -- Evidence suggests that COVID-19 was here in November, A version by the same author appeared on Medium, but was taken off.

Coronavirus: Light at the End of the Tunnel

• On March 11, the World Health Organization declared a Covid-19 pandemic
• On March 12, Hawaii decided that all large events are canceled. Disneyland announced its closing.
• On March 13, Pres. Trump declared a 'state of emergency' in the U.S.

Right then I started collecting data for the World and for the US. All my data were taken around noon from ncov2019.live, and rounded up to nearest hundred cases.

Here is the summary of my data and projections which suggest that there is light at the end of the tunnel.

The first three graphs show the number of cases for three weeks starting in mid-March. The second graph suggests that a change has occurred and that the rate of daily growth has started declining. The third graph suggests that daily growth has become 'permanently' under 20% and declining. The fourth graph summarizes these three weeks of 21 daily data points and shows a clear downward trend.

In this writing, the last data point was collected at noon on April 4. Where do we go from here? 

If the rate of decline is slow, as the third graph suggests, then the shape of new cases will follow the red line on the bottom graph. New cases will peak at the very end of April. Around mid-May, the new cases in the US will be the same as now at about 300,000 per day. This is a likely scenario. The likely maximum of infections in the U.S will be about 35 million, and the maximum of new daily cases of will be about 1.2 million.

If the rate of decline is fast, as the fourth graph suggests, then the shape of new cases will follow the yellow line on the bottom graph. New cases will peak around April 15 and on May 15, the US will record only 100 new cases. This is a wonderful statistical outcome but not likely to occur unless the mitigations, warm weather and other factors serendipitously conspire to put a lid on this pandemic. Even under this optimistic scenario, the number of infections in the U.S will be about 12 million.

I'll keep following the numbers but indeed there are statistical indications that there is an end to the 'Covid-19 tunnel' in late spring.

There is great risk in making forecasts using only a few and fairly volatile data points. Every week adds precious new data that enable better future predictions. I will leave this post alone and will post updates separately. In this way, we can see how close we got in predicting 6 weeks into the future based on 3 weeks in the past.

How Much Do We Pay for Roads and Other Utilities?

Robert Poole of the Reason Foundation presented a comparison below in which I added my data from Honolulu, Hawaii. Thanks to the 12 solar panels on the roof of my house, and my moderate annual mileage (about 11,000 miles at 20 mpg), my costs are similar or better than average US costs.

However, the data below do not include vehicle registration fees which are part of the road charges we pay. My vehicle's registration is just under $30 per month but most light duty trucks pay about $500 for registration on Oahu, which is over $40 per month. Even with registration included, the conclusion is the same. Roads are a vital infrastructure utility and we pay less for them than we pay for other infrastructure utilities.

=========== Poole's article:What Americans Pay in Highway User Taxes  ===========

HNTB Corporation last month put out a useful analysis that compares what Americans pay for roads and highways (via gasoline taxes) with what they pay for other basic infrastructure, such as electricity, water, cell phones, broadband, etc. I was not surprised to see that their results showed a far lower annual cost to use roadways (excluding tolled facilities) than for other user-charge-funded infrastructure. But I was surprised by how low the reported gas tax charge was.

In my book, Rethinking America’s Highways (University of Chicago Press, 2018), I presented a similar comparison, using data mostly from 2012-2013. My results were very similar to HNTB’s, except for the highway number. The comparative monthly figures are shown above.

My numbers make the same basic point—that people don’t realize how little they pay for roads compared with other basic infrastructure. But my fuel tax figure is about double that of HNTB. The answer appears to be that all HNTB’s figures are per household, except for fuel tax, which is per driver. By contrast, all of mine, including fuel tax, are calculated on a per-household basis.

I’m grateful to HNTB for making this kind of comparison, but we should not be presenting an unfairly low figure for what households pay for roads. The main point is to get people to understand that even $46 per household per month is far below what they pay for other basic infrastructure and is not sufficient to cover the capital and operating costs of our extensive roadway network.

Uber's Days Are Numbered

I have been saying this privately and on my Facebook page for at least two years. Uber's days are numbered. We just don't know exactly when it'll collapse. It really depends on the amount of fools willing to help it burn capital. Now hear it from Princeton's Alain Kornhauser below. (The linked article dances around the truth and provides vague and false hope.)

"At the size that they are now, neither Lyft or Uber are close to break-even. If they grow, it gets worse (unit labor charges go up and average revenue goes down, fundamental supply - demand). Driverless in a sufficiently large Operational Design Domain to substantially increase their size in not going to happen soon enough to save them as they exist today. They were just too early.

Their only "survival" option is to downsize by a factor of at least 10, reduce their valuation/stock price by a factor of at least 10. Become a "nice business" for 5-10 years and wait for Driverless aTaxis to become a reality and start this all over again.

Driverless is a necessary condition to make this into a network non-labor intensive business. Alain"

More Reasons to End HART Rail at Middle Street

City Leaders: Plans For Rail Work Along Dillingham ‘Not Acceptable’

My take is as follows. There are three choices.

Plan A.  Proceed as planned with terrible inconvenience for Kalihi, much more congestion for daily commuters, and financial ruin of many Kalihi stores. Also going to Costco, Home Depot and Best Buy will be a challenge with huge congestion effects on Nimitz. Hwy.

Plan B.  Tiptoe around the neighborhood which will extend project delivery time and cost a lot more. This option is likely not feasible. Can't build a quarter billion of elevated infrastructure without closures and major disruptions. This will wind up being like choice A, but with a higher cost.

Plan C.  End rail at Middle Street. This is the only reasonable choice. The rail project is largely useless and it keeps generating pains and costs. Ending it at the city's Middle Street Inter-modal Center is workable.

Plan C is an imperative, in light of these two headlines.

1. Next mayor will have mountains of problems, but mere molehill of money to pay for them. Yet, somebody has to do it. Hopefully he or she will make the hole a little smaller. (Not likely, based on past history.) I'm not interested. I was in 2008 and 2010 when the rail and homelessness holes were treatable. Now they are ever expanding craters...
2. This article relates to the fleecing of the taxpayer for the Public Private Partnership to complete the 4 miles between Middle Street and Ala Moana Center: City leaders playing hide-the-pea in rail financing scheme. "Few believe the city will complete Oahu rail to Ala Moana Center for the $9.2 billion total it projects, and we hear much speculation about the real final construction tab. $10 billion? $12 billion? $15 billion?"

Hawaii Remains 47th Worst in Assessment of State Highways

Quoted in front page article of the Honolulu Star Advertiser.

Panos Prevedouros, professor of transportation engineering at the University of Hawaii at Manoa, said that in general our rankings make sense. “Given our short distances and relatively slow speeds on highways, our fatality rate rank of 21st is above average (good) but it would be better with fewer DUIs and a motorcycle helmet law,” he wrote in an email. “As we know, pedestrian fatalities fluctuate a lot, but there has been a general increase for various reasons such as increased population age, increased tourism and traffic projects that provide a false sense of safety to vulnerable road users.”

State to Look at Building Parking for Laniakea Beach Park

UH Civil Engineering Professor Panos Prevedouros said he and his student recently looked at the pedestrian and traffic patterns near Laniakea Beach. He said every hour, there’s an average of “1,000 vehicles, 300 pedestrians.” “No sidewalks, no signs, no nothing. That’s why this area has been a problem for safety and congestion for many, many years,” he said.“No sidewalks, no signs, no nothing. That’s why this area has been a problem for safety and congestion for many, many years.” Prevedouros said he supports any solutions — long-term or short. “I understand it takes a long time to install long time measures but it’s already been a long time and they’re mired in their paperwork," he said. We need to keep the heat on this subject!

Wallet Hub: Cheap Car Insurance in 2019

Quoted in WalletHub.com analysis of car insurance.

Why do car insurance rates (and even providers) vary so much from state to state?

Mostly due to legal definitions of tort and liability as well as minimum required coverage.

Is it riskier to drive in some cities and states than others? Are the drivers themselves riskier?

Specific age groups and race groups have shown increased rates for one or several types of crashes. Some of these groups are over-represented in some states. Also very busy intersections, substandard freeway merges and high volume rural and mountainous roads have a higher incidence of crashes. The number of these "black spots" also varies by city and state. Weather creates variability in crashes too, i.e., there are more crashes in foggy and icy conditions; there are many states that do not have these conditions.

Is there anything that state and local governments do to promote cheap car insurance rates for their constituents?

Enact properly designed and enforced laws on speed, red light running, helmet usage, intoxication, etc. These vary widely from state to state and sometimes within a state.

Some Ways To Stop The Exodus To The Mainland

Quoted in an article on an important subject covered by Dan De Gracia.

Panos Prevedouros, chairman of the UH Civil and Environmental Engineering Department, says four dimensions are vital to retaining young people in Hawaii: “satisfying, well paying jobs; quality of infrastructure and built environment; housing availability and price; and the cost of living.”

I do have a few specific suggestions for the four items I mentioned to Dan, as follows:

1. Satisfying, well paying jobs... There is plenty good news here. Not only we have the lowest unemployment in the nation, but by 2020 the baby boomer retirement will become stronger. Engineers, business majors and other professionals will fare very well in job selection and remuneration.
2. Quality of infrastructure and built environment... This will remain a weakness as the state and city grapple with human centered issues (homeless and elder care), bad choices (rail and misguided energy endeavors) and generous promises (civil service employee retirement and health care) which leave very little left over for infrastructure improvements. Parenthetically, this is why I am no longer interested in running for executive office in Hawaii. My ability to deliver on these fundamental quality of life assets of society will be useless.
3. Housing availability and price... Leadership is needed to develop the remainder a Kakaako not as real estate safety deposit boxes for foreigners but as vibrant community for young (under 35) and old (over 65) with a fifty year P3, public private partnership, to develop reasonably priced rentals for unmarried young adults and for seniors in apartments with 1 and 2 bedrooms priced at, say, $1,200 and $1,600, respectively, with only 0.5 parking stall per apartment rented at $100 per month, plus incentives for transit and bicycle use. Three-four phases of about 500 units each will make a huge impact, and the amount of subsidy will be modest. The P3 is necessary to ensure quick, high quality development of the units and continuous maintenance for the life of the 50 year agreement; we do not want this done as a public housing project but as a long term for profit development with some taxpayer subsidy.
4. Cost of living... The subsidized apartments described in (3) above, in combination with adoption of non motorized transportation for short trips and car-sharing for longer ones, will allow the young to partly defeat Hawaii's high cost of living for a decade or more. Combined with a good income from the start, the young will be able to save enough to afford a house or large unit for developing a family and making Hawaii their forever home.

However, our politicians pay no attention and clearly have no sympathy for young adults making, say, $50,000 a year or more, who are contemplating the choice to stay in Hawaii, and barely make it, or leave Hawaii for better opportunities. They are busy with their liberal kuleana: Taxation, land control, environmental control, more control and regulation, the homeless, the poor, the "living wage" and the like. This tells us a lot about priorities and the future of Hawaii... For decades now, the young ones have heard this message loud and clear.

Self-Driving Cars Another Nail In Rail’s Coffin

Quoted in the article "Self-Driving Cars Another Nail In Rail’s Coffin "by Josh Mason

Panos Prevedouros, chairman of the UH civil and environmental engineering department, said at a Grassroot Institute of Hawaii panel on May 3 that the rail system is already obsolete because the share of public transit nationwide has already halved over the past few years that Uber and Lyft have grown exponentially.

There’s Still No Word On How Much Honolulu Rail Will Cost —To Ride

Energy Revolution Won't Come from Renewables

Well stated reality check in Want an Energy Revolution?

"For a practical example of the physics-anchored gap between aspiration and reality, consider Florida Power & Light’s recently announced plan to replace an old gas-fired power station with the world’s biggest battery... this battery “farm” will be able to store just two minutes of Florida’s electricity needs. That’s not going to change the world, or even Florida."

Vinod Koshla (of Sun Microsystems fame) had a similar opinion in 2011: "Environmentalists are fiddling while Rome burns. Forget today’s green technologies like electric cars, wind turbines, solar cells and smart grids. None meets what Khosla calls the “Chindia price”—the price at which people in China and India will buy them without a subsidy. “Everything’s a toy until it reaches that point.” (The Economist, March 10, 2011)

How Clean Is Your Electric Vehicle?

The correct answer is... it depends on the way that power is produced. For example, EVs are not very clean in Honolulu (top graph); hybrids do better. But Reno (bottom graph) has natural gas, geothermal and solar power production, so EVs there run much cleaner. Find out about EV pollution for your area by entering your zip code at the website of the Union of Concerned Scientists.

Feels Good to Be Ahead of Fellow Researchers

This 2019 paper concluded as follows:

"HEVs are rapidly emerging as a potential alternative to the existing state of transportation due to their lower petroleum consumption and toxic emission. Strict CO2 emission laws and increased public awareness will propel HEVs to be the future of road transportation." (Singh, K.V., Bansal, H.O. & Singh, D. J. Mod. Transport, Springer (2019) 27: 77, doi.org/10.1007/s40534-019-0184-3)

We reached a similar conclusion and for the same reasons four years earlier!

The HEV has the second lowest societal and consumer LCC compared with all other six vehicle types. Its ranking makes it a strong candidate as a transitional technology. Its low LCC resulted from the low emission impact cost, the improved fuel efficiency and the low manufacturing cost. In the short term, there are no barriers that should be overcome to increase the penetration of HEV in the market.  (Mitropoulos, L. and P. D.
