Designing and editing vertical alignments is similar to designing alignments, in that you can conveniently design and edit them on-screen taking constraining points into account. The relevant design data is displayed and synchronized in the various views, e.g. longitudinal profile, curvature string and cross-fall string.
In the card_1 system, vertical alignments are height profiles defined using tangent intersection points. They are used not only to describe the vertical profile of roads, railways and sewers, but also as height definitions for swales, ditches, carriageway edges and other alignment-related structures. Individual evaluations or evaluations as lists are integrated in the application.
You can use this module to calculate dependent vertical alignments for ramp alignments, or transform vertical alignments onto other more or less parallel alignments.
You can create engineering-grade longitudinal profile drawings with vertical alignments, longitudinal ground profiles, flexible annotations, curvature strings, cant gradient strings, sight distance strings or other strings.
These drawing components can be displayed together with tangent strings, dimensionings, drawing sheet borders and title block fields in a card_1 drawing.
This module enables you to optimize existing road surfaces and makes reconstructing existing traffic routes very easy.
The main field of application for this module is to calculate vertical alignments and to analyze vertical alignments for 'overlay' resurfacing of roads of any category. Based on a new genetic algorithm, the program automatically picks the optimum vertical alignment from a range of variations.
You can use this module to automatically generate cross-fall strings which conform to the relevant design guidelines and which are optimized in terms of vehicle dynamics. The road surface type, the vehicle dynamics parameters as well as the spatial route geometry are taken into account. The program supports any designs that conform to the relevant guidelines, roads with empirical parameters and inner-city streets with constrainments according to the German guidelines of the FGSV. The speeds are also taken into account. An interactive v85 speed generator is integrated in the program.
When dealing with routes which do not comply with the relevant design guidelines (especially existing routes), twist-related corrections may be defined to ensure controllable steering; the parameters required are simulated thus substantially increasing safety and driving comfort.
