Abstract: With the development and application of digital technology, the transportation infrastructure field is undergoing a transformation driven by digital applications and intelligent construction technology. This article focuses on the teaching reform of road survey and design courses under the background of digitization, deeply analyzes the shortcomings of traditional teaching models in technology integration and practical ability cultivation, and constructs a teaching system that combines theory and practice and cutting-edge technology application by introducing highway BIM design software and hybrid teaching mode. The aim is to enhance students'digital design ability and engineering practice literacy, and to provide high-quality talents for the transportation industry to adapt to the development needs of digitization.
