Using this module, data for a single ground cross-section may be imported from various file formats or entered manually. A long-section could be loaded or extracted from the cross-sections.

Up to 8 cross-section and long-section groups may be loaded. Any one or all of these groups may then be plotted. Earthworks volume calculations may be done between any two groups.

This module provides the user with user-friendly and very flexible road design functions. The vertical alignment design may be done directly on screen or it may be entered from external design results. It allows for non-symmetrical vertical curves and the checking of design limits. The cross-sectional profile is defined using the most advanced techniques in manipulating individual components independent from others for example :- road width and batter slope changes. An extensive verge design function supplements the basic design profile.

Variable drains, batter parameters and topsoil stripping may be specified. Calculation results include volume calculations for mass-earthworks, foundation layers, layers on shoulders, setting-out data, layer level and thickness checks and conversion of the final profile to DTM format.

For construction the contractor may enter design data from drawings or ASCII files.

The offsets and elevations forming the cross section profile at each peg distance may be edited on the graphic screen. This may typically be used to create a rehabilitation profile for quarries or mine dumps or for the definition of a benching profile in road cuttings.

Two single carriageway profiles may be defined independently with an offset between each other to define a dual carriageway road. All the functions for a single carriageway are used and each carriageway may have it's own vertical alignment. Cross-section drawings will show both carriageways. Earthworks calculations may be done for seperate carriageways.

After the calculation of mass earthworks volumes the result may be used to plot a mass haul diagram. The diagram is plotted in the form of a long section with user definable vertical and horizontal scales.

The horizontal and vertical alignment design is used to determine various design criteria. This module has 3 components:

• Calculate the RISE/FALL and curvature factors as required by HDM (Highway design and maintenance) document for the construction of main roads.
• Calculate horizontal and vertical alignment sight distances in both directions along the road.
• Calculate the 85 percentile speed profile in both directions to determine climbing lanes.
