Abstract
The start of work on the high-speed highway has become a real technological challenge. Since we are talking about a new high-tech railway facility, there is a need for fundamentally new engineering and technical solutions, innovative approaches to conducting surveys, designing, building and operating new rolling stock and infrastructure.High accuracy in the design, construction and maintenance of the railway track is of key importance in the creation of a high-speed highway. A thorough analysis of the experience of the world's leading organizations in China, Japan and European countries, specializing in the creation and operation of high-speed highways, shows that the most effective system-technical solution is the transition to the use of high-precision coordinate methods of design, construction and maintenance management of infrastructure and rolling stock.It is precisely the high-precision coordinate methods that open the way to the transition to the operation of the infrastructure in the design position. And this, according to the world's leading experts, is an opportunity to reduce the cost of the current maintenance of such an expensive infrastructure by 20-30%.The technical solution that ensures the use of coordinate methods in the" end-to-end " technological life cycle of infrastructure objects is the creation of a high-precision coordinate system along the directions of the high-speed highway.
