Abstract


Road network is one involving a wide range of investment capacity, long cycle systems engineering. Road construction road network planning is the preliminary work to develop a scientific road network planning and its implementation program to improve the road network can transport capacity , and promote coordination of road construction , orderly and rapid development, and can effectively prevent road network layout and construction blindness in repeatability and randomness, for road construction macroeconomic management and leadership to provide a scientific basis for decision-making . However, as the work of one of the highway network planning , how to determine the size of the road network development issues , in the domestic and international models and conclusive yet complete , but also the lack of road density than research . Road density is the road network planning, evaluation and other important indicator of the study was to investigate because not deep enough, tend to ignore the construction of the road network some negative effects , such as road network takes a lot of land resources, take up a lot of money and other issues , leading to road density determination of the reasonableness standard there are certain difficulties . Therefore, how to determine the road network density index , its intrinsic link between economic development , the existence of the optimal density of the road network , how to determine the optimal density of the road network and other issues , we need in-depth research . In this context, the paper reviewed the research at home and abroad on the road network density based on the results , pointing out that the current road network density Institute on some existing problems and proposed land productivity perspective from the optimal density of the road network idea . After about the road network density and land productivity concepts and their analysis of the characteristics , as well as the relationship between the two studies , laid the theoretical foundation. Then this marginal benefit from the allocation of resources and discusses two aspects of the optimal state highway network density , on the basis of dynamic and static proposed optimal density of the road network , and in the end of the article focused on relatively static optimal road network density of research methods. This established the optimal density of road network model , based on the road network density land productivity research methods to make a preliminary exploration . In this paper, both qualitative and quantitative aspects of the optimal density of the road network discussions , hoping to study road network density in some reference.
