Is a Vibrant City Best Measured at Night?

Wolfe identifies five important qualities of 24-hour, magnetic places, He argues that the first, safety, must be in place for the other four - mobility, proximity, commerce and interaction - to flourish:

"When evening light and crowds merge to create a sense of safety, where walking and transit define mobility and proximity, if commerce goes on without the sun, then human interaction with the built environment is a demonstrated success."
