Abstract
The study is aimed at improving highway alignment charts in order to improve the operating character-istics of highway sections, adapt them to regulatory requirements for heavy transport and reconstruct accident-prone sections based on information produced by state-of-the-art data collection systems for road objects without costly geodetic surveys. The article presents methods for constructing a digital preliminary trajectory of a highway using relationship databases and algorithms that implement these approaches according to data from video certification. As a result, a preliminary highway alignment chart that meets current regulatory documents is developed, including the impact severity of fences for heavy transport. It is noted that the problems of constructing preliminary alignment charts of high-ways for heavy transport in Russia could be solved without conducting costly geodetic surveys, but relying on digital trade and regional databases of road facilities, which are permanently updated by state-of-the-art data collection systems for road objects.
