Abstract

Abstract

Based on the concept of highway network equilibrium scale, the second-class highway was taken as the standard grade highway, the calculation method of equivalent mileage and equivalent coefficient was proposed, and the regressing model of terrain correction coefficient for highway network was established. The shortcomings and characteristics of traditional methods such as territory coefficient method and connectivity method were analyzed. The traditional calculation method of highway network equilibrium scale was adjusted. The minimum comprehensive Gini coefficient was taken as judging criterion, the range of equilibrium scale interval was adjusted, the calculation flow of equilibrium scale proportion was established, the systematic determination method of equilibrium scale for highway network was proposed, and example verification was carried out by using the highway network in Yunnan Province. Analysis result shows that the terrain correction coefficient of freeway in Qujing is the minimum, and is 1.12. The terrain correction coefficient of the fourth-class highway and substandard highway in Diqing is the maximum, and is 1.92. The equilibrium scale mileage in Nujiang is the minimum, and is 549 km. The equilibrium scale mileage in Qujing is the maximum, and is 4 753 km. By using the proposed method, the Gini coefficients of population, economy and area for highway network in Yunnan Province are 0.02, 0.19, 0.15, reduce by 0.15, 0.29, 0.18 respectively, the three Gini coefficients meet absolute equilibrium standard.
