Making the Most of the Rail Fiasco

This is a fuller version of the article I co-authored with Cliff Slater and professor Randy Roth that appeared on the Honolulu Star Advertiser on June 29, 2016.
----------------------------------
It’s now painfully clear, even to Mayor Caldwell, that the likely cost of taking rail all the way to Ala Moana Shopping Center would greatly exceed available funds.  That’s why the new plan is to stop at Middle Street, eight stops short of Ala Moana, at least until an additional $4 billion can be found.  Just weeks earlier, Caldwell and others were saying that it would make no sense to stop at Middle Street—rail needed to reach Ala Moana, at a minimum, or so they were saying before realizing that that money simply wasn’t there.

This financial nightmare only gets worse when one takes into account its impact on the Full Funding Grant Agreement.  This is a legal contract the City signed with the Federal Transit Administration as a condition of receiving a series of federal payments totaling $1.55 billion.  Because of the decision to stop at Middle Street the FTA, is now legally entitled not just to stop providing funds, but to demand the immediate return of nearly $0.5 billion already provided.

We believe that the FTA will be extraordinarily flexible in dealing with this financial train wreck, partly because the FTA’s own hands are dirty.  It knew very early on that City officials were neither competent nor honest. We base this on interagency email in which FTA officials commented on the City’s “lousy practices of public manipulation,” willingness to “deceive with no remorse,” use of “inaccurate statements,” and having a culture of “never enough time to do it right, but lots of time to do it over.”

FTA officials also noted that the City had botched three projects and were “well on their way to a fourth,” started construction this time “without authority despite warnings that it would create an ineligibility for the project,” and put itself in a “pickle” by setting unrealistic start dates for construction.

We also know that FTA officials had ready access to the report of independent experts hired by Gov. Lingle to provide a second opinion on the likely cost of the proposed rail system.  The group’s bottom-line assessment should have alarmed the FTA:  “A multi-billion dollar transportation improvement project, particularly one that is proposed to be operated in, and funded by, an urbanized area that is far smaller than the norm for such projects, should have its financial plan developed with methodologies that incorporate the highest professional and technical standards and techniques.  As we demonstrate [in this report], the financial planning and modeling process for [this] Project fails this ‘best practices’ test in many ways.”

The FTA also aided the City in its dishonest efforts to convince people that rail would reduce the current level of traffic congestion.  For example, the FTA publicly expressed belief that “this project will bring much needed relief from the suffocating congestion on the H-1 Freeway.”  This was contrary to the FTA-approved Final Environmental Impact Statement (EIS) in which the City had acknowledged that “traffic congestion will be worse in the future with rail than what it is today without rail.”  The FTA's statement also contradicted its own previous position in its January 2011 Record of Decision in which it stated:  "Many commenters [on the Draft EIS] reiterated their concern that the Project will not relieve highway congestion in Honolulu. FTA agrees..."

Despite these and many other indications that the City could never build rail “on time and on budget,” as Mayor Caldwell repeatedly promised, the FTA apparently buckled under political pressure when it entered into the FFGA.  Because of the FTA’s complicity in Honolulu’s rail fiasco, the FTA should now allow the city to use the $1.55 billion of federal money to make the best of a terrible situation that it could and should have prevented.

We believe the most attractive of the available options is to convert the existing rail guideway into dedicated lanes for a state-of-the-art Bus Rapid Transit system that extends not just to Middle Street but far beyond to Manoa, Waikiki and other parts of the island, including Waianae.  As the figure below shows, regular, articulated and double-decker buses will fit the existing rail guideway and will operate normally and safely with a guided-bus system similar to those running in Essen, Germany,  Adelaide, Australia and several other cities.

This could be done with the money that otherwise would be wasted on a rail system that was out-of-date before construction even began. A BRT conversion will use familiar technology, will have a higher ridership, will preserve bus routes, and will provide more traffic congestion relief than rail.

The Autobahn: Where "Speed Kills" Dies

The German autobahn is a traffic safety paradox. Countries like Australia, the US and the UK have made freeway speed control a major objective of their traffic safety code. Many high class roads in the US are limited to 55 mph and sometimes lower speeds. The top BBC television program Top Gear has scored big laughs with US speed limits.

Speed kills they say.  That can be true. In a case of loss of control or other accident conditions, a modest impact accident can become a severe or fatal accident if the speeds are high.  But speed itself does not kill. In a recent (June 2016) presentation at the German federal department of transportation that I witnessed in Berlin, the statistics clearly showed that the Autobahn is the safest German road.  Germany in general has better traffic safety that the US.  But the speeds on the Autobahn are insane.

Recently I drove about 1,000 km on several German autobahns connecting Berlin and Frankfurt.  When the road was not wet, I was typically using the middle lane and cruised at 150-160 km/hr for long stretches where no limits were in effect. That's 93-100 mph in a loaded car with a family of four!

But on occasion like the one below I'd move up to 176 km/hr or 109 mph and get passed quickly by a Hyundai SUV as in the instance below. The speeding of Hollywood car chases is common place with common cars on the German autobahn.

Note in the picture that the dashboard indicates to me the speed limit in the sign with the red circle and three dashes.  The dashes mean that no speed limit is in effect on that segment of the road. The dashes are replaced with applicable limits, most commonly 120 or 90 km/hr in sections with curves or other difficulties.  The Germans were very cognizant of these limits and adhered to them. On occasion I'd drive a little faster on those restricted stretches to pass the Porsches so I can enjoy the whoosh of being passed by them minutes later... Even when did 194 km/hr (120 mph) they zipped by me at , I'd guess, 155 mph which is a common governed speed limit (based on the tire type fitted).

And nobody died; not even close.  It was fun to see that the next city was 50 miles away and arrive there in about half an hour!

$10 Billion Is the Ultimate Price Tag for Honolulu's Rail Boondoggle

Back in January 2016 the Honolulu Civil Beat published my opinion with the title: $10 Billion: The Ultimate Price Tag for Honolulu Rail?

On Friday, May 13, 2016 the cost or rail was pegged by HART at $6.9 Billion.

On Sunday, May 15, 2016 the cost or rail was pegged by FTA at $8.1 Billion.

On March 20, 2016, the New York Times published an article that included my opinions with the title: Hawaii Struggles to Keep Rail Project from Becoming A Boondoggle.

Given these cost updates (while less that one third of the project has been built), clearly the question mark is no longer necessary, and the project is a verifiable boondoggle.  Thus:

$10 Billion Is the Ultimate Price Tag for Honolulu's Rail Boondoggle

I am sorry that Honolulu voters did not pick me in 2008 or 2010, or past Gov. Ben Cayetano in 2012 for mayor. Honolulu's punishment in now too severe, and we haven't seen the half of it yet. 

Engineering experts raise quality concerns over Honolulu’s rail construction

With Gina Mangieri of KHON Channel 2 News Always Investigating...

So we took a field trip with engineer, and prominent rail critic, Panos Prevedouros.

“One of the cracks in this area was pretty alarming and it was along the line of the segment,” he pointed out.

Other concerns have to do with the amount of rust, starting with tracks that the city bought early to hedge on steel price.

“Basic rust is not a problem. It’s actually a protective coating that, when the rail starts running, it will clear a lot of it,” Prevedouros explained.

But when it gets installed, more problems can arise. “One of the issues is that it creates problems with the labor that tries to install them. They may need extra protection because when you’re bolting them, there may be excessive dust of rust,” Prevedouros warns, which can be dangerous when inhaled.

Other rust hot-spots lie in the rebar forms that start each pillar.

“Here we see the rebar for the support columns,” Prevedouros pointed out, “and I am a little worried that it’s quite rusty, because when you pour the rebar around it, it creates problems with adhesion of the concrete to the rebar itself. In the long term, it may cause spalling problems, delamination problems.”

That’s not the only worry about the pillars, especially in certain parts of the route.

“The problem in general with Waipahu is it was famous for springs and underneath water caves,” Prevedouros said, “and this is a very heavy, very long bridge. Some of these pylons may have settlement issues. There have been reports that at least a couple of them have issues of settling. They’re going into the ground. Beyond a few inches, it becomes tremendously stressful for the structure and we probably need to add more to support the bridge.

“It could be sudden, but it could take several years,” Prevedouros added. “First, we’ll hopefully see cracks, but then we’ll have to react to it before we have a collapse.”

Quick reactions have to be at the ready on other key jobs along the building process, like when crews go to snug the segments together with cables in something called “post-tensioning” — something that brought a near disaster near the Banana Patch — which was memorialized in HART’s report as Span 258, NCR 509.

“They had a failure with a segment they were trying to post-tension it, which is the process this thing is getting built,” Prevedouros said, “but the tendons failed. There was essentially a minor collapse. Now they’re shoring it up to try to connect it with the two pieces to the left and the right. The whole segment seems to be supported from the bottom and they’re trying to fix the situation.”

“Does it run a future safety risk?” Always Investigating asked.

“The problem is now, by having this failure, it is costing a lot of time and resources to fix it,” Prevedouros said. “But they will fix it in a way that will probably be quite durable.”

Liang Shi: Will Driverless Cars Improve Traffic Congestion?

Many colleges and universities have a quick but tough competition among their graduate students called the 3MT or the Three Minute Thesis. Students stand up and deliver, in three minutes or less, a coherent and interesting summary of their research leading to their Masters or Doctorate degree.

I am very pleased that my PhD student Liang Shi competed among ~60 University of Hawaii at Manoa graduate students and got 2nd place.  Congratulations!

"You may have seen the news that Google is testing their Driverless cars in California. The car was designed to drive itself without any human intervention. It uses a rotating roof top light radar system (aka LIDAR) that maps critical components of the road environment, including curves, signals, traffic lanes, vehicles, pedestrians and bicycles. It also maps cones and construction zones for avoidance. It has no driver controls, such as steering wheel or pedals. It is believed that driverless cars can reduce traffic accidents and congestion. But last November, a Google car was pulled over by the police for driving too slowly, which generated my research question ”will driverless cars improve traffic congestion?” My research is to estimate how driverless cars affect the traffic flow of freeways and city streets.

For example, take an intersection controlled by a traffic light , when the traffic light turns from red to green, it takes 1 second to 3 seconds for human drivers to perceive the change of the signal and react accordingly by switching pedals. For a driverless car, it only takes 0.3 seconds to do so. Driverless cars use sensors and cameras to detect the traffic lights.  They can communicate with the local controller that operates the traffic light. For advanced driverless cars, called connected vehicles, they can talk to each other exchanging information of location, speed and other parameters. Imagine if all the cars at the signalized intersection were driverless cars: They would all start at the same time without the human response delays. So the road can serve a larger amount of traffic in the same amount of time. In addition, driverless cars are equipped with collision avoidance technology, so if a regular motorist violated the red light, the driverless car would not enter the intersection and it would avoid the collision.

Based on my analyses, if all vehicles are driverless cars, capacity of the road will be doubled. This means that every city intersection would have twice as many lanes at no cost to the city.  But if in the future we only have 1% of driverless cars in traffic, traffic flow will not improve. If we have 5% driverless cars, congestion will improve by about 5% if they are regular driverless cars, or by 12% if they are connected driverless cars. So with 5% driverless cars, traffic flow will begin to improve in a noticeable way. However, if the cars are designed to drive conservatively, they will cause more delays than humans do.

To answer my research question, which is “will driverless cars improve traffic congestion?” the answer is that if driverless cars become dominant in the market and if they are designed to drive very closely to each other, then they will reduce traffic congestion, possibly by a lot. "
