THE THEORY OF MODELING SPATIAL LENGTH OF THE TRACK
The article deals with the method of determination of spatial length of the track, allow providing significantly improve the accuracy and quality of the design solutions. Developed the method of determining the actual length of the track, differs in that space to the length of the route is determined as the sum of the spatial lengths straight, horizontal and vertical curves. For the construction of mathematical models of track are some of the possible use cases for the various geometric curves.
