Research On Flyover-crossways In Sanyan Bridge Area In Foshan City

Accompanying our country economy's quick-developing, traffic needing increases rapidly on quantity and quality ,as a result ,our country's road network and city road network have faced more and more pressure, and traffic problem becomes grave gradually. As one kind of high-grade form of road hub (road crossways) ,the flyover is a road net high-effect change functional traffic facilities ,so it will play more and more important role in road network.Foshan, as an important part of City Circle of Guangfo, the road network of this area plays an important role in the region of Pearl River Delta. Research on the road network nodes, it' s good for layouting and implementation of road planning between roads and roads ,and roads and railways. improving the whole competitiveness in the economy development of City Circle of Guangfo in Pearl River Delta. In this paper, the author carried on design and planning of flyover-crossways according to the traffic status in Sanyan Bridge area in Foshan City, and made a reasonable evaluation of programs, the research mainly includes the following two major parts:The front chapters and sections mainly introduces theories .while introduction, the author takes Huangqi fly-over crossways as an example to analysizes. According to engineering construction principle, from technology ,economy, function and environment 4-big index system ,the author will ascertain flyover-crossing valuation index system, for the purpose of easy to carry out, index system will be subdivided; After system index system is builded-up, the article will introduces the methods which can be applied to carry out valuation. At last, this article will introduce the principle and mathematical operation of AHP and fuzzy systemic analyses which are often used in multi-purpose analyses. The latter half part is demonstration analyses. Taking the research subject of traffic solving scheme of Sanyan Bridge area in Foshan City into account, taking Huang Qi flyover-crossways as example, this article will build entire valuation index system, quantization method and valuation method. At last the article will use AHP and fuzzy systemic analyses to analysize Huang Qi fly-over crossways, so as to judge its scientifically and pragmatism.
