Updated Reality for Autonomous Vehicles

 Quote

In March 2018, Waymo confidently forecast that “up to 20,000” electric Jaguars “will be built in the first two years of production and be available for riders of Waymo’s driverless service, serving a potential 1m trips per day”.

Two months later, it added that “up to 62,000” Chrysler minivans would join its driverless fleet, “starting in late 2018”.

Today, there is little sign that any of these vehicles have been ordered and Waymo’s official fleet size remains just 600.

Experts Weigh in on Current Job Market Trends

 Career advice, including mine, for graduating civil engineers.


In your opinion, what are the biggest trends we'll see in the job market given the pandemic?

Panos Prevedouros Ph.D.: Most jobs will be in Engineering disciplines needed for infrastructure maintenance, upgrade and replacement. Also a lot of new developments have been deferred by the pandemic, and if there is no surprise in the lending rates, development will grow and possibly skyrocket in 2022 and beyond.

Engineering disciplines related to transit will shrink. Transit has lost about 80% of its riders and is unlikely to regain many of them, for reasons such as depleted municipal budgets, desire of people to avoid dense crowds well after the pandemic ends, and robocars becoming established in 5 to 10 years.

Rail’s Completion Takes Construction to 2033!

Even the rail project’s harshest critics think the mayor’s 2033 completion date estimate is overly pessimistic.

“He pushed it all the way to 2033. That’s 13 years. It’s like we’re restarting the project from scratch,” said University of Hawaii Civil Engineering Professor Panos Prevedouros.

Under the city’s estimates, contractors would be building the remaining four miles of the guideway and the rail stations at a rate of about 1/3 a mile each year, which is very slow by most standards.

“Inch by inch, foot by foot ― yes,” Prevedouros joked.

But he also believes that both the city’s and HART’s cost estimates are overly optimistic.

“My anticipated total costs for this total project will be in the order of $13 billion,” he said.

Panos’ Estimates Rail Cost to Reach at Least $13 Billion

In fact $13 billion is a rock bottom estimate of total costs from project inception in 2006 to project completion and full commissioning into revenue service in 2026 (or later.)

If HART rail were to start operations today, it would get about 20% of the expected opening day forecast ridership.

Unlike a large metropolis with huge demand for commuting trips (where rail makes sense), HART rail will be a costly and environmental disaster for decades.

The only "solution" is to cut it short. Complete 16 miles to the Middle Street intermodal center and stop the bleeding there.

Belated Praise from Bob Jones!

Praise from Bob Jones? It's 2020 after all! Mahalo for the acknowledgement. When it's all said and done, I'll be 3x correct. Plus one. The first three were cost, complexity of delivery, and low ridership (~50% off TheBus.) The plus one is the new normal: Zoom and telecommuting, distancing requirements, shrinkage of services, and Uber and automated vehicles/robotaxis.

===============

Covid-19 is, understandably, #1 on the news cycle in Honolulu these days. But we have a Primary election coming Saturday and I wonder if everyone will forget and forgive about the train cost and delay.

The local gadfly Panos Prevadouros — who’s probably a much better civil engineer and professor than a would-be politician — got some of it strikingly right in his long fight against the elevated train project.

When the cost was just $5 billion, he showed that even if it served 7% of Oahu travelers (the City figure) it would be an irresponsible expenditure.

Little did we guess that the final cost might be $10 billion and the finish date so far in the future that we might all be traveling by air cars or rocket packs by then!

And to think that we embarked on this project with just 50.6% of those who voted saying yes to it. Not exactly a resounding huzzah.
