The least important concept for diversifying modal choice today is the concept of intermodalism.

According to the chapter on the topic of Transportation Energy Technologies coauthored by myself along with Lou Albright and Lars Angenent, there are five alternative end-point technologies that might eventually power the transportation system. Of the five, which three do we argue are practical for widespread use in the short- to medium-term?

Electricity, hydrogen, and sustainable hydrocarbons

Hydrogen, compressed air, and sustainable hydrocarbons

Compressed air, electricity, and sustainable hydrocarbons

Hydrogen, compressed air, and electricity

In the flow-density relationship, total flow per hour can be calculated based on density of vehicles on the roadway and which of the following?

Time-mean speed

Space-mean speed

Either time-mean or space-mean speed

Neither time-mean nor space-mean speed

The film Revenge of the Electric Car describes Tesla Motors executive Elon Musk as following the maxim from Sung Sus Art of War that you should go where your enemy isnt.

True

Roll-on roll-off, loading of truck trailers, and loading of shipping containers are three systems that exist to transfer shipments from the road to other modes at the intramodal transit point.

True

False

According to the America 2050 report, the most important reason that high-speed rail (HSR) is anticipated to be the most significant transportation mode within emerging U.S. megaregions is that:

HSR can reduce energy consumption and CO₂ emissions compared to highway or air modes.

HSR is ideally suited to providing economically competitive service in the range of 200 to 500 mi of travel.

Airports within megaregions will become so congested that there will be no other choice but to shift to HSR.

The construction of HSR systems will be the economic engine that will drive the formation of megaregions.

The National Surface Transportation Infrastructure Financing Commission (NSTIF) states that although the current fuel tax paid into the Highway Trust Fund is financially inadequate, it at least has the benefit that it is indexed to inflation and therefore increases by a small amount each year.

Truck trailers represent a relatively untapped opportunity for reducing aerodynamic resistance and improving fuel economy.

True

False

According to Schafer et al. in the article about the Other Climate Threat, it is observed about daily travel patterns that:

As people grow wealthier, they can afford to spend more time everyday traveling.

Poor people are under more financial pressure so they spend more time everyday traveling than wealthy people.

Both low-income and high-income people spend roughly the same amount of time everyday traveling.

None of the above were observed in the article.

Shipping containers and truck trailers in the continental North America is one of the largest intermodal freight shipping operations in the world today.
