# Research on Automatic Generation of Park Road Network Based on Skeleton Algorithm
## 7 Conclusions and Future Research  
This study focuses on the park road network, integrating the skeleton algorithm from computer graphics into conventional road network design and investigating methods for generating park road networks. It incorporates spatial syntax theory to validate the findings. By inputting semantic information during road network generation, it amalgamates domain knowledge of park road network design to precisely shape the network. The study employs a modified Douglas-Peucker simplification algorithm to streamline polygons while retaining geometric scale and semantic information. For small independent morphological areas in parks that are closely situated, a convex hull operation method is utilized to ensure the smoothness of the road network. Using Houxianghe Park as a case study, this research evaluates design schemes based on connection value, depth value, etc., revealing well-connected roads with high permeability and accessibility; those around water bodies exhibit higher usage frequency. These results indicate that the proposed design aligns with actual usage needs and meets target requirements for road network design. The innovative approach employed in this study can swiftly furnish designers with effective reference solutions, thereby enhancing their work efficiency.  
Subsequent work can be further improved in the following three aspects:  
1. The design of road networks is a creative endeavor that often incorporates esthetics and culture and is inherently subjective. In the future, it will be important to address the challenge of integrating algorithmic principles with design creativity, such as utilizing artificial neural network models, integrated generative adversarial network technology, or equation algorithms to assist designers in achieving esthetic excellence.
2. The spatial layout of a road must accurately reflect the complex multi-dimensional elements and consider various two-dimensional, three-dimensional, macro, and micro design needs. These include overall land use planning, cost considerations, terrain changes, road slope, volume, width, function, etc. When generating the geometric algorithm for a road network, it is essential to incorporate more elements related to park planning into the environmental restriction framework to meet future needs.
3. Due to space limitations, this study is unable to evaluate and verify the scheme from multiple perspectives. In the future, the skeleton algorithm can be further associated with different evaluation methods to validate its rationality. For example, it can be compared with traditional design methods or deep learning methods in order to enhance its functionality.
