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.
