times wider in 1950 than it was 150 years earlier, yet it still took only an hour to traverse. The rule has since been dubbed Marchetti’s Constant.

travel time between such radically different lifestyles inspired Cesare Marchetti, the Venetian theoretical physicist, to suggest that there was a ‘quintessential unity of travelling instincts around the world’ and that this unity resulted in a fixed ‘travel time budget’ that he named after himself as Marchetti’s Constant.

become the development hot spots of tomorrow. New mobility systems will change our cities and buildings once again. In 1994, Italian physicist Cesare Marchetti described a principle, now known as “Marchetti’s constant.” He found that, in general, people are willing to commute for about one hour a day, or a half-hour one way

in a bigger home. The race will be on for the first hyperloop-integrated skyscraper. Autonomous vehicles (AVs) could desensitize people to distance, possibly lengthening Marchetti’s “constant” of commuting time. Without having to attend to the wheel, you can now sleep in your car, or conduct online meetings there. Perhaps you can

. (While it might not carry as many people, a hyperloop’s higher speeds would prevent people from otherwise taking a more carbon-intensive ride.) If Marchetti’s constant continues to hold, building new developments around faster forms of mobility may further encroach on untouched land, destroying habitats and threatening ecosystems.

Zahavi’s fascinating observations made a powerful impression on the Italian physicist Cesare Marchetti, who was a senior scientist at the International Institute for Applied Systems Analysis (IIASA) in Vienna. IIASA has been a major player in questions of

As a rough guide it clearly has important implications for the design and structure of cities. As

planners begin to design green carless communities and as more cities ban automobiles from their centers, understanding and implementing the implied constraints of Marchetti’s constant becomes an important consideration for maintaining the functionality of the city. 4.

It may be explained, at least in part, by a concept known as the "Marchetti Wall."[62] Back in 1994, the Italian physicist Cesare Marchetti observed that throughout history—going back to ancient Rome—the majority of people disliked commuting more than one hour to work.

A System Without a Schedule While consulting for General Electric in the early 1970s, a playful, forty-something-year-old Italian nuclear physicist named Cesare Marchetti became friendly with one of GE’s in-house economists.
