FUNCTIONAL SPECIFICATION OF STRATEGIC URBAN FREIGHT MODELS: MODELING ATTRIBUTES FOR THE PORT AND LANDSIDE FREIGHT TASK IN SYDNEY

Infrastructure suppliers and operators, either government utilities or private enterprise, need to be involved in strategic freight processes at the urban scale. This is to ensure that infrastructure investment remains effective in facilitating whole network access and minimizing impacts in often congested and competitive networks. Infrastructure suppliers and operators need to be equipped with a capacity to gauge demand matching and demand steering concerns. In Australia, strategic urban planning, especially the freight task, remains piecemeal. This potentially leads to infrastructure investments that neglect or exacerbate existing system deficiencies. We analyze existing system conditions for the Port-Landside network and arrangements in Sydney. From a review of current freight modeling capacity, we develop a freight modeling taxonomy. This taxonomy is translated into a functional specification for infrastructure suppliers and operators through an analysis of their modeling needs with respect to inter-modalism. We present this as a general freight transportation infrastructure planning procedure.
