Yes, we can, according to this dissertation from Göteborg University, which deals with the impact of road tolls on car use, factors that influence attitudes to road tolls, and road tolls in comparison with other types of steering mechanisms targeting automobile use. But you have to have a positive attitude toward cutting down on car use (which people rarely have) and you have to plan how to go about it and regularly monitor your progress in relation to a realistic goal. Otherwise routines and impulsive actions, especially shopping, will prevent any decrease in the mileage you chalk up.
The dissertation brings forward some factors that lie behind the predominantly negative attitude car-owners have toward tolls for road use. The greatest impact is tied to how fair people feel the tolls are: the less fair they are, the less likely people are to favor them. The sense of being deprived of personal freedom also affects people’s attitudes. People are more favorably inclined to other types of steering instruments that are not economic in nature, such as a zone where automobile traffic is banned in central Göteborg or information campaigns targeting the individual driver.
A field study showed that the impact of road tolls on driving habits was minimal. The only drivers who drove less were those households that got together to plan their trips. The fact that people do not drive their cars less even though they might have economic reasons to do so is not simply a matter of not wanting to or not having any alternatives. Many car trips are undertaken as a matter of routine, with no weighing of alternatives, with no conscious choice being made, and this is difficult behavior to change. On top of this there are a substantial number of unplanned trips, that is, trips we don’t normally make and didn’t plan on making. On the average, people make one such trip every day. The dissertation shows that these are primarily shopping trips, giving someone a ride somewhere (especially in families with children) and trips to the doctor, and households maintain that this unplanned driving is the result of unexpected events that are beyond their control.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
