PROGRAMMSYSTEM ZUR OPTIMIERUNG DES STRASSENENTWURFS. TEIL VII. OPTIMIERUNG DER TRASSE IM LAGE- UND HOEHENPLAN (PROGRAM SYSTEM FOR THE OPTIMIZATION OF HIGHWAY DESIGN. PART VII. OPTIMIZATION OF HORIZONTAL AND VERTICAL ALIGNMENT)

As a further development of the model conceptions with respect to the partial shifting of the horizontal alignment, this paper will demonstrate how the EPOS program system, with a corresponding expansion of the model, can be used for a controlled optimization of horizontal and vertical alignment. The interrelationship between the horizontal and vertical alignment models is thereby affecting the optimum alignment. Hence it was necessary to adjust the existing cross section model, linking the various section models, to meet the changed requirements. The integrated data flow was decisive for the objective. The principles required for developing the system have already been described. The system expansions were carried out to be able to use the EPOS system for the determination of an optimum alignment by means of implied and explicit employment of individual programs. With an example, the possibilities this program system can open up to highway designers in practical engineering are pointed out.
