Peak Travel has probably been reached with the current paradigm. There is still plenty of energy for travel if we change paradigms. The physics is simple, it costs less to move less. In congested, repetitive travel, why are we moving a ton to move a person?

We can build a physical-internet. This is the application of ultra-light rail networks.

Here is a link to the CSX commercial where they ask the reasonable question, "How much can a 50 miles per gallon vehicle (Prius) do for the environment?" And answer it as the Prius drives onto a rail car "not as much as the car that carries it." As they explain how they can move a ton of freight 423 miles on a gallon of fuel.

Morgantown's Personal Rapid Transit (PRT) system opened in 1975. It has delivered 110 million injury-free, electrically powered passenger miles.

Masdar, the zero-carbon city, is being built with PRT as the internal transport system.

Heathrow is being expanded using PRT.

PB-244854, from the Congressional Office of Technology Assessment in 1975 sketched how PRT can make our cities independent of foreign oil.

Booz, Allen, Hamilton's study in 2007 for the State of New Jersey affirms the findings of PB=244854. There are similar finding by the EU.
