Although there are a wide variety of urban spatial structures, a large share of metropolitan areas can fit into four types: Type I (Completely motorized). This spatial structure is characterized by low to average land use densities. The automobile-oriented network assumes free movement between all locations with public transit having

However, performance is a multidimensional concept as different metrics can be used to assess it. The above figure illustrates two urban transportation

These priorities are well represented in the allocation of space along the right of ways devoted to urban circulation. The above photo depicts a corridor of circulation located

Source: adapted from R. Tolley and B. Turton (1995), p. 63. Different urban transport modes have different operational speeds and capacities. The car is obviously the least efficient urban transport mode in terms of capacity (between 1,000 and 3,000 persons per hour), but the fastest, most convenient, and flexible. Urban

Communing is an important component of urban mobility since it accounts for a large share of urban movements and substantially impacts the commuters’ welfare. The time spent

Source: Millennium Cities Database for Sustainable Transport. The strong association between density (number of people per hectare) and car use (share of car use for commuting) indicates that modal preference, urban form, and density are closely related. For Houston and Los Angeles, dispersed developments and low densities leave limited choices

The urban spatial structure considers the location of different activities in central areas and the periphery. A central area is a cluster of core and/or central activities, and the most central area of a city is usually labeled as the central business district (CBD). Core activities are those of the
