City draws the line to thwart speedsters along busy Aiea road

Quoted in a story by Alexander Zannes in the Channel 2 News (KHON2) on narrower lanes for neighborhood streets, as follows.

Panos Prevedouros, chair of the Dept. of Civil and Environmental Engineering at the University of Hawaii says is a proven method to reduce speed, “In general I will tell you that if it is a neighborhood street, narrow lanes to a point are actually good at controlling the speed, again you have to be careful of wiggle room and having sideswipes if they overdo it.”

State reviewing procedures after fiery Atlanta bridge collapse


Interviewed for Hawaii News Now story on State reviewing procedures after fiery Atlanta bridge collapse by Allison Blair.
  • "The hodgepodge of activity that we have under the freeway overpass, it's not appropriate," said Panos Prevedouros, Chairman of the U.H. Civil Engineering Department
  • Prevedouros says the combination of trash, vehicles, tires and tanks could be disastrous if fire broke out.
  • In 2016, firefighters responded to seven rubbish fires in the area. Fire department officials say all were small, with no damage or serious injuries reported. 
  • "It takes a really long time. A five minute fire cannot bring a bridge down," said Prevedouros.
  • But a fire burning at an extremely high temperature, for an extended period of time, can weaken the metal rebar that supports the concrete and cause a collapse. Prevedouros says its rare, but it's also why you shouldn't store a lot of combustible material underneath the viaduct.
  • Hawaii News Now asked Prevedouros if what happened in Atlanta could happen here, with the viaduct in its current state. Prevedouros said "potentially."
  • The fire department doesn't inspect state property, but said it would provide recommendations to the Department of Transportation if it was asked to.
  • Transportation department officials declined to be interviewed for this story but said bridge inspections happen every two years, and that inspectors will be reminded to check for combustible materials.

In this episode of Moving Hawaii Forward, Tim Apicella welcomes Dr. Panos Prevedouros, Professor of Transportation and Chairman of the Civil Engineering Department of the University of Hawaii (UH Manoa), to cover a variety of topics ranging from the Honolulu rail boondoggle, Hoopili traffic impacts, smart city street intersections and rapid transit.

HART on Fox News

I was included in the Fox News story featured today (March 17, 2017) about Honolulu's rail project.

"Honolulu's rail transit project is years behind schedule and billions over budget;" William La Jeunesse reports from Hawaii...

Troubled transit project a taxpayer boondoggle in paradise?

Vehicle Taxation by Mileage -- California Simulation

At a recent ASCE* web discussion board the subject was VMT taxation which is scheme where the usage of roads (mileage or Vehicle Miles of Travel or VMT) is used as a base to collect highway taxes in addition to or instead of the fuel taxes.

I'll discuss the pros and cons at another time. There are many and quite complicated pros and cons because of the means and technologies involved, the rates involved and of course the "big brother" syndrome, all which open a Pandora's box of social, political and taxation implications.

Meanwhile a user on the board posted a number of interesting pictures of his simulated VMT highway tax collection along with a sample bill, as shown below.






Clearly, the system knows the driver's exact route, his speed compliance and provides ratings for his braking and cornering performance. Too much info in the hands of the government, right?

In California they still exempt electric vehicles from taxes, but part of the the VMT tax justification is to address the disparity of EVs using highways but paying no fuel tax. This is another controversy.

An overarching question is this: Is a complex system for VMT tax collection and the necessary big government behind its oversight and administration worth it? How much of the extra taxes will actually wind up spent of highway maintenance and improvement?
