Algorithm development and optimization for road/railway alignment design
Abstract
Algorithm development and optimization for road/railway alignment design does not just demand theory implementation and conversion of mathematical formulas into code. Additionally, there arises a need to perceive theory from another point of view and implement innovative calculations - algorithms and vice versa. This research project investigates two main subjects, useful for the design and construction of road/railway structures. In particular, transition curves are examined as well as the total slope of the road that affects road drainage. Specific emphasis is put on the application of algorithms. Thus, the first subject of this thesis, includes the analysis and comparison of the most commonly used transition curves in road and railway design. More precisely, clothoid, three types of cubic parabola and a newly introduced curve named “Symmetrically Projected Transition Curve“ (SPTC), are evaluated as transition curves between a straight line and a circular arc. The calculations of eac ...
