Rob Greenfield cycled “4,700 miles across the United States on a bamboo bicycle, using only water from natural sources, avoiding fossil fuels almost completely, supplying your few electrical needs with solar power and creating nearly zero waste”.
He’s done lots of other ‘silly’ things, like wearing all the rubbish he generated over the course of a month and travelling without spending money from Brazil to Panama.
A street in Oakland recently underwent a road diet: two of five lanes were converted into protected bike lanes. The result is an increase in biking and pedestrian use, a decrease in collisions, a decrease in speeding, and an increase in business along the street.
Road dieting seems to be happening a reasonable amount in London at the moment, particularly around the improved Cycle Superhighways.
Braess’ paradox or Braess’s paradox is a proposed explanation for a seeming improvement to a road network being able to impede traffic through it. It was discovered in 1968 by mathematician Dietrich Braess, who noticed that adding a road to a congested road traffic network could increase overall journey time, and it has been used to explain instances of improved traffic flow when existing major roads are closed.
