Type I - Completely Motorized Network
Characterized by low to average land use densities, this automobile-oriented city assumes free movements between all locations. Public transit has a residual function while a significant share of the city is occupied by infrastructures servicing the automobile, notably highways, on-street parking and parking lots surrounding activity centers. Most activities are thus designed to be accessed by the automobile. This type of urban structure requires a massive network of high capacity highways, underlining that urban efficiency and productivity is dependent on road accessibility. Secondary roads converge at highways, along which small centers are located, notably nearby interchanges. This system characterizes recently set North American cities where urban growth occurred in the second half of the twentieth century, such as Los Angeles, Phoenix, Denver and Dallas.
