NETWORKS IN ROAD-BASED TRAFFIC

To achieve a high degree of coverage over large areas together with a high utilisation of resources the transportation companies have been forced to consolidate goods in larger and fewer warehouses. The requirement for a high utilisation of resources and a high capacity of the flows in the network means that the speed of the flow must be constant throughout the whole system. It is possible to achieve this by connecting a number of well-defined spokes and hubs in a network to establish transport channels: the channel concept. The possibilities of taking advantage of the benefits of a channel concept in a consolidation network have been analysed. This concept will result in a better customer service level in terms of higher frequencies and the maintenance of short transportation times. There is, however, a lack of related measures and measurements. This thesis also describes and defines concepts and terminology concerning network and network efficiency in road-based line traffic and a model for measuring network efficiency. The model includes parameters like the number of consignments out of, or activities in, an industrial area, possible addresses in the vicinity of a node, and the possibility to deliver within a defined time space. Different ways of analysing the effectiveness of an existing line-based terminal structure are carried out by using the model. The efficiency depends on which measure is used, i.e. the measures must be related to the purpose of the measurement. The results of the model are analysed in relation to empirical data concerning economic and time-related efficiency measure within existing systems. (A)
