ABSTRACT
This chapter reflects the assumed needs of the reader, is devoted primarily to management of quantitative data. Generally speaking there are two distinct concepts of quantitative information systems—the "data bank" and the "management information system." Geographic controls-or "geocoding," as the subject is more popularly called—are especially needed in metropolitan transportation studies, where data is highly disaggregated. The geographic control system that emerged in the 1960s consisted of means of relating the various geocoding subsystems so that data could be disaggregated or aggregated to the appropriate scale. The new Census procedures proved very helpful to continuing transportation planning, not only in simplifying geocoding preparations, but in facilitating the coordination of interactions between the transportation system and other urban systems. The first classification regarding building entry offers two types of land-use surveys, which Chapin and Kaiser call the inspection type and the combined inspection-interview type.
