Coordinate Inverse and Automatically Mapping of Roadside Stakes for Complex Curve Route
Authors: , , ,
Abstract: With construction of high-speed railway, coordinate inverse problem, especially adopted in more complex types of transition curves becomes time consuming and error prone. The traditional methods in practice have shorts of only applying with limited types of curves, complexity, and tedious. In this paper, a new inverse algorithm is put forward, which is suit for various types of curves and the first iteration point is not necessary to be input but can be random. The iteration can be ensured to be convergence. In this article, using of this algorithm, software has been developed for lofting any types of transition curves by language C# and ACCESS, which makes the laying work more accurate and quick compared with that by hand calculator. The location of the roadside stake is showed by the use of graphic controller Teigha.net API. Tests with existed works show that this method is feasible and it can provide more accurate results quickly and automatically
