Cinqüenta por cento dos acidentes de trânsito acontecem nos cruzamentos. Gary Lauder  compartilha uma idéia brilhante e barata para ajudar os motoristas a moverem suavemente: um sinal de trânsito que combina as propriedades de "parar" e "preferência" - e pede que os motoristas sejam educados.

O novo sinal de trânsito de Gary Lauder: revezamento

Crashes at intersections account for half of all traffic accidents, making intersection design a critical safety issue. Converting signalized intersections to roundabouts can cut crashes by 40 percent and fatal crashes by 90 percent. However, installing unnecessary stop signs wastes time, fuel, and money—just one can cost over two million dollars across its lifetime. The solution may lie in rethinking our signs entirely, proposing a new hybrid that encourages drivers to take turns and keep traffic flowing.
