The Study On Layout Planning Of Intra-region Highway Freight Transportation

With the development of economic society in our country, highway cargo transportation has come into the period of comprehensive progress. And the frame of highway freight system is coming into being. Highway freight hub is a very important part of highway freight system. The layout planning of highway freight hub is of great importance in the construction of highway system.To make the National Highway hub Planning more standardized and scientific, Ministry of Transportation established " the master compiling method of highway hub". The unveil of the method plays an important role in the construction of highway freight hub. However, the research report of highway freight hub nowadays still has many disadvantages. The following passenger will introduce three disadvantages in the report and the measures to improve them.1. The connection of highway freight hub planning and regional economic society is not strong. The paper will introduce the elements that involve with the regional highway freight hub and analysis their relationship. The elements include the regional economic development, the city form and planning that the hub exists.2. The quantity, scale and location of highway freight hub are always qualitative. The mathematic model and quantitative calculation is seldom. The paper will establish a mixed integer programming model to calculate the number and scale of the freight stations. Because of the complexity of the model, this paper will turn to the software Lingo to solve the model. The model will be applied in the layout planning of Quzhou freight hub.3. The construction order of highway freight stations lacks basis, In the research report of highway freight hub nowadays, the construction order is mainly determined by the market demand for services and the building process of the professional market. The construction order is a very important part in the construction decision of the hub, so it must be quantitative to make the order more scientific. The paper will modify the the analytical methods of the traditional node and put forward the highway freight station demand index to arrange the construction order.
