Self driving cars could free up rush hour traffic

March 7, 2015, KTH Royal Institute of Technology

A fleet of shared self-driving cars in Stockholm could reduce rush hour traffic volumes by 14 cars for every shared vehicle, according to researchers at Sweden's KTH Royal Institute of Technology.

Meanwhile, the remaining automobile commuters would need only 20 percent of the metropolitan area's existing parking spaces, their study says.

The study sheds further light on what can happen if cities build on the growing interest in car-share programs and other alternatives to car ownership, indicating that self-driving technology could be a game-changer.

"Driverless cars are the smart car, and just as revolutionary as the smart phone," says Pierre-Jean Rigole of KTH Centre for Traffic Research. "They will revolutionize car ownership, lead to more flexible , with far fewer crashes. And they will free up valuable space in cities that is currently occupied by parked cars."

Rigole says the study looked at the possibility of a fleet of 9,700 Shared Autonomous Vehicles (SAV) with four seats each being introduced to the Stockholm metropolitan region, where an estimated 136,000 automobiles are driven in the daily commute.

Already in Stockholm taxi traffic accounts for half the total traffic, with about 272,000 such trips daily.

The study also presupposes that people agree to carpool, and that they accept 13 percent longer travel times plus a wait time of six minutes before the self-driving car arrives to collect its passenger. The study took account of only car-based commuting within the greater Stockholm area—not long trips or mode-shift from public transport, that is, people who could switch from commuting by public transportation to commuting by self-driving .

Quiet and clean electric vehicles will free us up for other things. And make us safer at the same time.

No more fumes from filthy fuels. Induction chargers for quick charging without cables. A good future.

-Like littering up science blogs with worthless comments and lies about imaginary accomplishments? Vandals should be engaged in more worthwhile pursuits.

Vandals don't care about facts for instance that induction charging is extremely wasteful. They just like using terms like this to imply they are more knowledgable than they actually are.

Those of us in the electric utility business pumped money into these since the late 1970's, getting the technologies up to where they are today. I am surprised they did not take PV installations as their own, providing home and business power, as well as that for transportation. It is limited thinking, and is now punishing the stalwarts with the loss of exclusivity of power generation.

Those who have no experience in this do not have not much to say of interest or value.

The good news is we now have really good sets of teaching tools to have our kids learn how to take care of the future of transportation. I am teaching one person now the basics of electronics, circuits, and coding, control, and then on to wireless sensors and the integration of components, sub-assemblies, and systems for synergy. I wish we had this stuff when I was a kid.

Detroit carmakers are opening significant research and design facilities in Silicon Valley, where I used to work. They are trying to adsorb what they can from California Thinking.

I say adsorb instead of absorb for obvious reasons - the inability of organizations to change.

And those egomaniacs who have experience as job shop validator form filler-outers (and power point presenters prepared by genuine experts) think that this experience makes them experts. That, and reading back issues of mother jones.

How pathetic.
