ABSTRACT
In view of the rural road network layout optimization existing the problem of the theoretical road network deviating greatly from the actual road network, this paper uses the categorical and hierarchical nodes importance calculation method and emphasis on calculating the importance of nodes and sections, which is combined with the actual situation of social economy, land, population and infrastructure. This paper screens unreasonable section importance and uses the improved Prim maximum tree algorithm to form the theoretical layout of rural roads based on the equilibrium section importance method, which is taken maximum sum of section importance as the optimization objective. Finally, taking rural roads in Anji county as an example, this paper verifies the feasibility and rationality of the improved node importance method.
