How the Science of Walking Will Shape Cities

For decades, automobiles have taken priority over pedestrians in city planning offices. That is set to change as we come to grips with what actually makes cities work: pedestrian traffic.

What's the Latest Development?

The need for social cohesion, as well as a greater understanding of how pedestrians behave, is changing how planners plan tomorrow's cities. What is called 'shared space' is becoming increasingly popularareas of the city where pedestrians, cyclists and motorized traffic mingle. Typically free of barriers like curbs and handrails, planners say shared space not only creates a more pleasant atmosphere for pedestrians but also makes the area safer, as drivers are encouraged to pay closer attention to their surroundings.

What's the Big Idea?

A strong scientific undercurrent is changing the way we think of cities, where more than half of the world's population currently lives. Sociologists are better understanding a phenomenon known as 'desire lines', or the path humans naturally take while walking rather than ones they are forced to follow because of sidewalks and handrailsthink of worn down paths in the park which veer off from the officials trails. In general, humans seem to prefer trajectories that afford them the most visibility, suggesting open, vibrant spaces.

  • Some inventions can be celebrated during their time, but are proven to be devastating in the long run.
  • The inventions doesn't have to be physical. Complex mathematical creations that create money for Wall Street can do as much damage, in theory, as a gas that destroys the ozone layer.
  • Inventors can even see their creations be used for purposes far different than they had intended.

This 5-minute neck scan can spot dementia 10 years before it emerges

The results come from a 15-year study that used ultrasound scans to track blood vessels in middle-aged adults starting in 2002.

  • The study measured the stiffness of blood vessels in middle-aged patients over time.
  • Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.
  • The scans could someday become a widely used tool to identify people at high risk of developing dementia and Alzheimer's.
