About the Street Network
The street network is constructed in a hierarchical manner to provide efficient and effective routes from one’s origin to destination. Arterial streets form the backbone of the street network. These high-capacity roadways serve as direct links between different areas of the city.
Local collectors feed into these arterials, allowing motorists quick and easy access to the major roadways while at the same time allowing pedestrians and bicyclists to move about their neighborhood and to move from one to another. The majority of streets in the city are local neighborhood streets. These streets provide residents access to their houses.
