Road authorities typically manage large numbers of standards and guidelines, which are relied upon not just by their own technical staff, but also industry and local government authorities. With the advent of generative AI Large Language Models (LLMs), Main Roads Western Australia asked the question – Can LLMs enable the automation of identifying document cross references and assist with prioritising key document updates? We present the results of a trial on various road design and operation documents where LLMs were able to identify document cross references, custodians and key dates with 95% accuracy.
