Abstract

This invention discloses a parametric design method, system, device, and medium for road vertical planning. First, it processes multi-source, heterogeneous raw surveying data, transforming it into structured digital terrain assets. Next, it constructs a logical topology for the road centerline, assigning it engineering semantics. Then, it performs vertical parametric design on a three-dimensional terrain benchmark. Following this, it conducts earthwork balance analysis and three-dimensional visualization based on the design scheme. Then, it uses a built-in specification library for intelligent diagnosis and optimization of the scheme. Finally, it transforms the complex design results into standardized digital deliverables and a visual interactive interface. This completes the fully automated layout design process from raw CAD data to digital deliverables, solving problems such as fragmented processes, low iteration efficiency, and delayed compliance review in existing technologies.
