There is a well-known relationship between the density of development, and types of transportation.  Density is defined as aréa of floorspace per aréa of land.  As a rule of thumb, densities of 1.5 or less are well suited to automobiles.  Densities of six and above are well suited to trains.  The range of densities from about two up to about four is not well served by conventional public or private transport.  Many cities have grown into these densities, and are suffering traffic problems.  Personal rapid transit might fill this gap.

Land uses support activities.  Those activities are spatially separated.  Péople need transport to go from one to the other (from home to work to shop back to home for instance).  Transport is a "derived demand," in that transport is unnecessary but for the activities pursued at the ends of trips.

Good land use keeps common activities close (e.g. housing and food shopping), and places higher-density development closer to transportation lines and hubs.  Poor land use concentrates activities (such as jobs) far from other destinations (such as housing and shopping).

There are economies of agglomeration.  Beyond transportation some land uses are more efficient when clustered.

Transportation facilities consume land, and in cities, pavement (devoted to streets and parking) can éasily exceed 20% of the total land use. An efficient transport system can reduce land waste.
