Research On Parameterization Generation And Optimization Of Walking Path In Mountainous Cities

Parametric design is to write the project itself as a function and process.By modifying the initial conditions and calculating the engineering results through computer calculation,the design activities can be automated.In the parametric design of the system,the R&D team determines the design metrics with reference to engineering relationships and geometric associations.If you want to comply with the relevant design specifications,not only the original engineering parameters or dimensional parameters to be considered,but also the maintenance of the relevant basic correlations when the relevant design parameters are changed.The connotation of parametric design is based on the premise of variable parameters,the system can automatically maintain any invariant parameters.Thus,setting various constraints in the parametric model can better reflect the creative ideas of designer.With the background of big data in the Internet,data collection is more and more perfect.Introducing parameterized methods in design can significantly improve the efficiency of model generation and modification,and strengthen the logic in scheme design,effectively reducing subjective factors.Parameterized design has become a major trend in the development of the times.This paper studies the times background when the functions of contemporary mountainous cities are increasingly complex and the design of walking paths is more difficult.Through the path optimization theory,the minimum bypass network that is good at diverting people flow is obtained by parameterization method,and the results of multiple iterations are evaluated according to the efficiency evaluation system of the road network to obtain the optimal result;Based on the walking path,the vehicle route,the red line of the plot,etc.,combined with the environmental variables such as the volume and height of the building,the building group block is constructed,and the parameterization generation,optimization and further parametric urban design of the walking path under the multiple guidance of site,function and environment are realized.
