As we finished the introduction of the book, everyone knows Jane Jacobs argued that the urban planning in our cities. In chapter 3, she write about the contact that uses of sidewalk. At first, she mentions that people loitering on the busy corners and those people have passed a judgment. She think if they had decent homes, they wouldn't be on the street. So the point is that she attempt to explain the safety issues on the sidewalk. Other, she tells reader that the public sidewalk life related to the local city's organization directly. Next, she wrote that efficiency of public sidewalk characters declines rapidly if too much burden is put upon them. In conclusion, the sidewalk is also an impotant component, to progress cities and change the ethos of a city should start at the streets-sidewalk of cities.
