Research Of County Highway Network Planning Method On The Background Of New Socialist Countryside Construction

County highway is the prolongation and complementarity of main stem highway, it is an important component part of regional highway network and has the extremely important effect in driving the development of countryside. However, with the ceaseless advance of New Socialist Countryside Construction, delay problems of our county highway planning and construct are increasingly emergence, it become one of the most important problems to restrict the development of county areas. Therefore, potentiate the research of county highway network planning and construct on the background of New Socialist Countryside Construction has very important practical significance.The research work of this thesis is based on the background of New Socialist Countryside Construction. It starts with the influences which caused by courty highway planning and construct in courtryside economy and dimensional structure, points out the significance to potentiate the research of county highway network planning and construct, it also summarize problems which exist at present in our county highway network planning and construct. Exactly comprehend traffic characteristic of country highway is the important assurance which is scientific ensurement in county highway's planning and construct, the thesis firstly analyzes the new influences that caused by New Countryside Construction based on the analyses of conventional county highway's traffic characteristic, and then brings forward target and fundamental of county highway network planning. Based on these researches, according to the new requests of county highway network planning and construct that caused by New Socialist Countryside Construction, thesis takes some new research on the basis of analysing the conventional country highway network planning methods, improves the veracity of crunodes by using amendatory crunode important degree model, then founds county highway network planning layout and grade optimization model to improve the scientific of highway network planning, it also gives an evaluative of county highway network by using network power fuzzy connectivity method. At last, the thesis chooses Dongai County of Jiangsu province as an actual research example, gives the highway network planning by using the method that bring forward in thesis based Donghai county's New Countryside Construction.The research of this thesis is an attempt in the county highway network planning on background of New Socialist Countryside Construction, which hopes to have certain instructional significance for the county highway network planning and construct in the New Socialist Countryside Construction.
