Creating Livable City Streets

In 1981, a Berkeley urban design professor named Donald Appleyard published a book called Livable Streets (now out of print). In it, he described the results of research he’d done in the late 1960s about the effects of car traffic on the people who live in cities. For the study, he selected three similar residential streets in San Francisco that only differed in the amount of street traffic and then measured how the residents used their streets.
