MEASUREMENT OF URBAN COMMODITY MOVEMENTS

An analytical framework for summarizing small commodity movements within an urban area is described. This methodology for measuring urban goods movements consists of a series of operations that process data on commodity shipments and the activity system to provide an input- output summary of selected urban commodity flows. Initially freight service zones are established for the study area, and classification systems are developed for commodity flow origins and destinations and for categories of small commodities. Commodity movements are represented in terms of temporal, volumetric, and spatial dimensions to show variations in demand for commodity transport. Relationships are then developed between commodity demand (flows) and activity units to establish the input-output model. The resulting information aids the development of a forecasting methodology of the demand for urban goods movements. The areal flow measures are analogous to the outputs of the distribution phase of the urban transportation planning process and, accordingly, give loadings that can be simulated on alternative delivery system designs to render measures of performance for evaluative purposes. A direct firm-based commodity shipment survey procedure is recommended to obtain the essential planning data currently lacking on goods movements.
