Rearview Mirror: 5 Vehicular Tunnels Were Built out of 14 Proposed

Quoted in Bob Sigall's article Rearview Mirror: 5 vehicular tunnels were built out of 14 proposed

Pali Highway to UH
Panos Prevedouros, professor of transportation engineering at the University of Hawaii, proposed this tunnel in 2012 to alleviate H-1 congestion. One tunnel could provide two lanes in each direction, he said.
===========
I was surprised that Bob Sigall discovered this tunnel proposal I studied with James Tokishi (a UHM CEE graduate) for HDOT. As far as I know, it has not been published anywhere. It was supposed to be a low clearance double-decker single bore tunnel (like A86 in Paris*), roughly from Pali Hwy. at Kuakini St. to Wilder Ave. at Dole St.

Honolulu to Ewa Beach

In the late 1960s a tunnel under the entrance to Pearl Harbor was proposed by the state House of Representatives to help leeward commuters get to town more quickly. It could shave 30- 40 minutes off their commute, some felt.

DOT Director Fujio “Fudge” Matsuda said the tunnel would be 7,000 feet long and cost over $750 million (in today’s dollars).

High maintenance costs, vulnerability to tidal wave inundation and Navy objections sank the idea then, but it gets resurrected every now and then. [That's right! See below]

Pearl Harbor Tunnel is a reversible 2-lane relatively short tunnel under the entrance of Pearl Harbor with cut-and-cover sections through the Honolulu International airport, priority lanes along Lagoon Drive and direct connection to the Nimitz Viaduct. Nimitz Viaduct is a 2-lane reversible “flyover” from the Keehi interchange to Iwilei.  Drive times from Ewa to downtown would be reduced from 65 to 11 minutes and the traffic reduction on Ft. Weaver Road and H-1 Fwy. would bring those commuter times down from 65 to 40 minutes.

Hawaii’s Infrastructure Gets D+ in 2019 ASCE Report

From a timely article in the Honolulu Star Advertiser: Panos Prevedouros, a transportation engineering professor at the University of Hawaii, said a new federal infrastructure plan “is very realistic,” but “I don’t know how much of this chunk will come down to us, because at 1.5 million (people), we’re really a very small state.”

He also takes issue with some of the grades given by the ASCE. “I believe some categories were doing even better than what is stated, and some others are probably worse,” he said.

Energy and solid-waste management are better than their C- and C grades, he said, “but then some areas such as roads and bridges — we would probably be below what is reported there.”

Long time ago I had time to keep track of my appearances on TV... 2003 to 2008.
Then in 2008 I run for mayor (try 1 of 2) and lost count... 

Randal O’Toole: Poor and Young People Are Fleeing Public Transit

Transit ridership has been declining now for four years, and the latest census data ... reveal that the biggest declines are among the groups that you might least expect: young people and low-income people. These results come from the American Community Survey, a survey of more than 3 million households a year conducted by the Census Bureau. Here are some of the key findings revealed by the data. …

The largest declines in transit commuting, both nationally and in the Washington DC urban area, are among younger people. Commuting forms only a part of transit ridership, but to the extent that declining ridership is due to ride-hailing services such as Uber and Lyft, those services are disproportionately used by people under the age of 35.

Although transit subsidies are often justified by the need to provide mobility to low-income people, the reality is that transit commuting by people in the lowest income classes is shrinking while transit commuting is growing fastest among people in the highest income classes.

Transit commuting is increasingly skewed to people who earn more than $75,000 a year. Even though only 19 percent of American workers were in this income class in 2017, they made up 26 percent of transit commuters, an increase from just 14 percent in 2005. Both the average and the median income of transit commuters are higher than those of all workers.

Honolulu Traffic Relief?

Quoted in three recent articles on traffic congestion relief authored by Marcel Honore in the Honolulu Civil Beat.

• Want Real Traffic Relief? Give Oahu’s Students And Workers Flexible Hours (Feb. 8, 2019)

"Occasionally, I’ve heard locals lay the blame on the University of Hawaii Manoa, with its approximately 24,000 students, faculty and staff.

Officials there point out that the campus already staggers its start times. On average, less than 20 percent of the student body starts classes at 8 a.m., according to Dan Meisenzahl, the university’s spokesman. It’s the “poster child” for staggered hours, added Panos Prevedoruros, who chairs the Department of Civil and Environmental Engineering there.

The problem, both Prevedouros and Meisenzahl said, is the parking."

• How Many More Cars Can We Cram On Oahu? (Feb. 1, 2019)

Panos Prevedouros, who chairs the University of Hawaii at Manoa’s Civil Engineering Department, further suggested tolls and pricing schemes to discourage drivers from using the roads when they don’t have to.

• What Would You Pay To Drive During Honolulu’s Rush Hour? (Jan. 9, 2019)

“Theoretically this can all be done, but the devil is in the details,” said Panos Prevedouros, who chairs the Department of Civil and Environmental Engineering at the University of Hawaii Manoa.

Prevedouros supports congestion pricing. It could take hold in Hawaii with the growing local concern over climate change and interest in ways to reduce its impacts, he said.

“It’s a win-win,” Prevedouros said. “Put some costs to the congestion.”

2018 Was a Disaster Year for Hawaii

... We survived all these:

• Ballistic missile threat
• Kauai floods and new US record for 24 hr rain
• Aina Haina floods 
• Big Island earthquakes 
• Kilauea eruption and Fissure 8 crater
• Six hurricanes; Lane, Olivia and Norman hit the state
• Same old, same old election results
• Record pedestrian deaths
• Rail continued to burn a couple million dollars per day
