A literature search and canvass was conducted to provide a better understanding of the effectiveness of existing land use controls and other techniques on the continuing utility of transportation systems. The study included a review of urban structure, an analysis of existing land use controls, their objectives, limitations, and stability, an analysis of highway system functions, access control and design control in relation to land use, and a review of traffic generation characteristics. The study concluded that many existing land use controls are dynamic and changing, and further evaluation of the significance of these changes on transportation facilities is needed. Recent planning programs indicate that future community plans and land use controls may be more realistic and stable than in the past. Land use decisions should be accompanied by an assessment of the transportation improvements needed to provide the required service. Land use controls could be used to achieve a mix of land uses with complementary traffic generation characteristics and also to distribute major generators to minimize traffic concentrations. The major problems with most existing highways can often be traced directly to the lack of access control. The expanded use of land access controls and geometric design controls can provide intrinsic protection for the highway. In the vicinity of freeway interchanges, access and design controls and special interchange design could minimize current operational problems.
