Appleyardobserved this by finding three blocks of houses in San Francisco that looked much alike and had the samekind of middle-class and working-class residents, with approximately the same ethnic mix. The differencewas that only 2,000 cars a day ran down Octavia Street (LIGHT street, in Appleyard’s terminology) whileGough Street (MEDIUM street) was used by 8,000 cars daily, and Franklin Street (HEAVY street) hadaround 16,000 cars a day. Franklin Street often had as many cars in an hour as Octavia had in a day.Heavy traffic brought with it danger, noise, fumes and soot, directly, and trash secondarily. That is, thecars didn’t bring in much trash, but when trash accumulated, residents seldom picked it up. The cars,Appleyard determined, reduced the amount of territory residents felt responsible for. Noise was a constantintrusion into their homes. Many Franklin Street residents covered their doors and windows and spent mostof their time in the rear of their houses. Most families with children had already left.Conditions on Octavia Street were much different. Residents picked up trash. They sat on their front stepsand chatted with neighbors. They had three times as many friends and twice as many acquaintances as thepeople on Franklin.On Gough Street, residents said that the old feeling of community was disappearing as traffic increased.People were becoming more and more preoccupied with their own lives. A number of families had recentlymoved and more were considering. Those who were staying expressed deep regret at the destruction of theircommunity.
