Research on the Application Method and Optimization Scheme of Highway Route Design Index
With the acceleration of urbanization,people's traffic demand is also growing.However,due to the huge differences in terrain,environment,population distribution and other factors in different regions,the traditional design mode can no longer meet the increasingly complex and changeable needs of people.Based on the analysis of the design of a high-grade highway with low traffic volume in mountainous areas,this paper summarizes the application method of highway route design index,and puts forward the optimization scheme of longitudinal slope length,slope,curve radius and sight distance.The results show that the slope of 6%-7%,the maximum slope length of 500 m,and the minimum slope length of 195 m are the best optimization values.The research content of this paper provides a more flexible and diverse design ideas for the planning and construction of highway transportation infrastructure in the future,and promotes the sustainable development of urban transportation system to a certain extent.
