Part 1
Hawaii: Big Changes and
Better Options
Hawaii 8-5
85% of the people drive alone
85% of the food is imported
85% of the electricity is not
renewable
85% of the people drive
• Yet the focus is on rail and bicycles… each one about 1%... So we pay billions for rail and lose lanes to bikeways to get from 85% to 83%!
• Result: Too much congestion by 2030 and we’ll have lost a few lanes and several billion $ that could have been used for congestion projects
• Action: End rail at Middle St. intermodal center, and refocus on traffic congestion
• Driverless technologies and “automated Uber” will make public transit obsolete before 2050
85% of the food is imported
• Worse yet, government approved the replacement of Aloun Farms with 12,000 cookie cutter, low density homes
• Result: Bad for agriculture, bad for rail, bad for traffic congestion
• Action: Rescind Ho’opili development. Re-zone Kalihi and require higher density in the remainder of Kapolei, Makakilo and Mililani
85% of the electricity is not renewable
• Solar and wind made inroads but dealing with their intermittency is very expensive (batteries)
• Expanded HPower is often underutilized bring some trash from Maui on empty barges
• Geothermal is Pele’s gift to her people but geothermal development has been vilified due to poor leadership
• Action: We need to follow Iceland’s lead on geothermal power exploration or we’ll suffer with costly and inferior power production alternatives

Sample Solutions …
(1) Middle St. Merge Fix
2001 computer simulation representation of
widened Middle Street merge and EB H-1
Freeway.
It was constructed and opened to traffic in
June 2014.
(2) Pearl Harbor Ferry
Waiting to get on the Pearl Harbor Ferry

2014 “PRICE POINT” PORT OF MIAMI TUNNEL
The Port of Miami Tunnel is a major construction project in Miami, FL with a final cost of under $1.1 billion. The project includes a 3/4 mile (1.1 km) long split portal automotive traffic tunnel. The project was temporarily cancelled in late 2008 due to the financial crisis but was resumed in 2009, with construction commencing in May, 2010, and the tunnel opened in May 2014. A private consortium called Miami Access Tunnel LLC, now MAT Concessionaire LLC, is in charge of designing, building, operating and financing the project.
• Length: 0.75 miles (1.21 km) • Number of lanes: 2 in each direction • Highest elevation: Sea level • Lowest elevation: −120 ft. • Width: 43 ft. per tunnel

(4) Underpasses
Pali and Vineyard now
Pali and Vineyard underpass
(5) Nimitz Viaduct: 3 lanes, 1 Lane off @ Waikamilo
(6) Traffic Signal Optimization
A 5 second reduction in
the average stopped
time results in:
• 7,000,000 gallons of
fuel reduction per year
• equal to removal of
14,000 cars from traffic
• Much quicker trips
(7) College Express
Minneapolis-Saint Paul, MN: BOSS Miles = ~290
(8) BOSS… Bus On Shoulder System (MN, NJ, NC, Canada)
Honolulu: Aloha Stadium Express BOSS Miles = ~10
Aloha Stadium Loop: 16 miles, 10 stops, 30-36 min.
Aloha Stadium Express From Aloha Stadium parking To Moanalua Fwy Exits at King St, onto a
dedicated lane on King St Turns on Maunakea St Turns on Hotel St Return via Alakea St and
Vineyard Blvd Onto H-1, Moanalua Fwy To Aloha Stadium
(9) Added and Contraflow Lanes
New Paris A86 tunnel under
Versailles (2 meter limit)
Also considered for Los Angeles
(10) Pali to UH Tunnels
Secret Scenario 2: Medium Express Tunnel
Two lanes per direction, ~2 miles
Access at Bingham St., Alexander St., Pali Hwy., Vineyard Blvd., University Ave.
Note: tunnel, transition and surface link
Part 3
What’s the Next Big Change
for Transportation?
Or maybe not…
What’s the business model?
• An early driverless feature will be auto-
parking
• Cars will park 2” apart instead of 2’ apart
• UH parking structure capacity can
increase from 5,000 to 6,000
• $5,000 more weekday revenue for UH!
Why own more than one car?
• Need a ride? Use an app and order a
driverless car or taxi pod
• Cost to user under 50¢ a mile
• Average cost to own a car is well over
70¢ per mile
• A car is large investment that for most
people sits parked 22+ hours a day
Much lower car ownership means…
• Much lower need for parking lots were
cars sit while the owner works, shops,
exercises…
• Frees up parking lanes
• Frees up large parcels for re-development
• More space for people in increasingly
crowded cities
What about traffic congestion?
• If we could have automated cars overnight,
congestion would disappear overnight
• They have no perception and reaction losses
• They drive at uniform speeds
• The drive close to each other
• All 2-lane roads can become 3-lane roads
• 2x Capacity per lane
• 3x Capacity at signalized intersections

?
Near term vehicle automations
• Ubiquitous autopilot for low-speed smooth
flow … enhanced adaptive cruise control
• Ubiquitous auto parking function
• Driverless long haul trucking, with drivers
for “first and last mile”
• Driverless BRT for trunk city routes
• Ubiquitous driverless pods on campuses,
airports, national parks, etc.
