Research on road express freight transportation network layout in shandong province

With considering the geography, planning of highway network, and the development of road express freight transportation network layout in Shandong, which is influenced by the socio-economic development, other modes of transport and the layout of traffic aisle and arterial highway the size and grade of road network, the objectives of express freight transportation network layout are put forward, and the objectives are differential, developing, reasonable and efficient. In order to achieve the objects, the first is to analysis Shandong freight traffic location lines, and then it can be summarized as the pattern of two horizontal lines and four vertical lines. Then the importance of node is measured by three indicators in the cities of Shandong: population, gross industrial output value and government revenue. The all cities can be classified into three categories according to its node importance. At last the best multiple tree of express freight network layout is achieved. This result is the strategic blueprint of express freight transportation development, and will determine the size and characteristics of regional express freight transportation development in a large extent.
