Flyover Traffic Rings

One in Athens, Greece connects two arteries to a freeway (Attica Tollway, top.)

The other in Shanghai, China removes pedestrians from a complex 5-approach roundabout (bottom.)



Circuit of the Americas: Racing to the Finish

"When in 2010 the city of Austin, Texas, was awarded the United States Grand Prix for 10 years, plans to construct the Formula 1 racetrack there, the Circuit of the Americas, quickly got under way, and an unlikely midsize civil engineering and surveying firm was awarded the civil engineering design contract."

This is a fascinating story of infrastructure development for a top flight world sporting event. Read this open article starting on page 64 of the Civil Engineering Magazine, May 2013 issue, of the American Society of Civil Engineers: Racing to the Finish.

Tesla Is Reinventing the Industrial and Infrastructure Process

Tesla is not only reinventing the car...  They are reinventing applied science, industrial product development and infrastructure planning.

At Toyota "we get a lot of standards and specifications, then we build a prototype and test it. At Tesla they get the standards and specifications set, and then change it on the fly. They spend more time in the validation phase. We spend more time in up-front planning.”

Typically we plan and design infrastructure (e.g., energy and transportation systems) too much. But rarely we go back and validate whether systems really worked as intended...

Unofficial assessments:
  • Did the H-3 Freeway meet its traffic target?  It exceeded it.
  • Did the Kal. Hwy widening relieve Hawaii Kai to Kahala trip times? Travel times were reduced by over ~25%.
Official assessments:
  • Do modern (built after 1995) light and heavy rail systems in any city in the US meet or exceed their planned ridership that justified their construction, after 5 or10 years in operation?
  • Nine out of 10 failed to do this. Several of them spectacularly. The largest US failure (after Tren Urbano in Puerto Rico) will be Honolulu.

City Transport 2020: The Future Can't Come Soon Enough

Here is a sample compilation of technological breakthroughs reported in the second half of May 2013:

CNN: The future of travel: How driverless cars could change everything

The Economist: The future of the car -- Clean, safe and it drives itself

The Economist: How does a self-driving car work?

The Economist: Tesla "General Electric Motors" has high hopes for its high-spec electric cars

Daily Caller: Tesla electrifies the auto market (This week American electric auto manufacturer Tesla Motors (TSLA) broke $100 per share.)

INRIX Expands Real-time Traffic Coverage: US, EU. Traffic conditions in Honolulu at noon on May 29, 2013 compiled as a digital layer that can be used by in-vehicle, broadcasting and other means are shown at the end of this article.

New Geography: Driving Trends in Context
Figure 4: Drive alone, carpool, motorcycle and telecommuting are over 90%.

I foresee an epic battle: Google and the Technologists vs. Sierra Club and the Greenies.

Where are the Planners and Transit in this bright future? They are largely Irrelevant!

Back to now: Sadly greenies, liberal politicians and urban (transit) planners continue to waste a huge portion of public and transportation funds on Smart Growth, Rail Starts and Complete Streets. Like the current Plan Bay Area 2040 plan that allocates 62% of the transportation funding to the 10% mode of transportation.(1)

The new wave of automated urban transportation cannot come soon enough!



---------------
Note (1) Plan Bay Area Report: “The analysis for the most recent regional transportation plan, Transportation 2035, suggested that the region’s transit system is not sustainable based on current projections of transit costs and reasonably anticipated revenues. Transportation 2035 identified a region-wide transit capital deficit of $17 billion and operating budget deficits of $8 billion over the next 25 years.” These are staggering deficits for a transportation mode used by 10% of commuters and less than that by non-commuters.  Planners acknowledge that these deficits are not sustainable for the community. Yet Plan Bay Area calls for more deficit-making transit.


Honolulu Recycling Guide

The proper way to recycle household solid wastes in Honolulu is explained in this installment of my O'lelo show PANOS 2050: Solutions for a Sustainable Hawaii.

This subject was also covered in a pictorial guide a few months ago in this blog.
