Program Description

HighRoad is an interactive graphical application for the geometric design of roads and highways. It makes use of the proven graphical interface of modern operating systems so you can use the program immediately without learning complicated commands or special formulae. You don't need to be a computer expert to use HighRoad - its icons and graphics make it intuitive and quick to use.

Road design is fast and interactive with HighRoad. Even complex design elements such as intersections and cul-de-sacs are automatically created for you. HighRoad's proven "embedded intelligence" ensures that these elements remain synchronised as you make adjustments to your design. While it has a great amount of intelligence built in, HighRoad also provides you with the flexibility to override its decisions when necessary. The elegant interface of HighRoad means that it can be used for a variety of civil engineering tasks. As well as road design for subdivisions, highway planning, highway relocation, haul roads, and widenings, it has also been used for drainage channels, pipelines, retention basins, conveyor routes, open cut mines, race courses, airport runways, and so on.

Technical specifications

Digital terrain model

Ground model information is read from floppy disks or CDs, across a network, direct from data loggers or from the keyboard. A variety of common formats can be used - points list, DXF, MOSS, CivilCAD, compass & clinometer, cross sections, and raw readings from a range of data loggers. HighRoad joins feature strings automatically according to a feature library.

Typical sections

Typical sections are easily designed using a range of kerb, pavement and batter types. These can be selected from a palette of tools in the typical sections window. Simply select the edge and pavement types from the palette of tools and then locate these in the required position on the screen. Cut and paste from a typical section library making the design of complex carriageways easier.

Horizontal alignment

The ease of designing both horizontal and vertical alignments is one of the most impressive features of HighRoad. Multiple horizontal alignments are quickly laid out on the terrain model using the mouse. The horizontal curves, including transitions, are automatically calculated and inserted as you drag the horizontal intersection points.


Intelligent intersection design automatically calculates the geometry and grading of an intersection or cul-de-sac. This is done instantly when it is first created it and whenever any adjustment is made to the roads that make up the intersection. The intersection can be dragged along the main road, or drag the main road and the intersection will go with it. It even automatically calculates the interaction between batter slopes.


The ground profile of the alignment is plotted on screen at a range of scales and vertical exaggeration. Intersection points are positioned using the mouse and can be easily and quickly moved to optimize the design. Vertical curves of parabolic form are automatically inserted and this enables you to quickly position a trial grade line on screen.

Cross sections

Cross sections at any chainage can be instantly displayed. Look quickly through a series of cross sections by simply pressing a button to view the next or previous section. The format of cross sections can be easily changed.


HighRoad uses the information provided in the typical section, profile and horizontal alignment to produce the plan view. Any changes made will be immediately reflected in the plan. You can choose which aspects of the terrain model and roads to display in the plan view.


HighRoad calculates earthworks quantities or a mass haul diagram and allows for the topsoil stripping and strata such as rock.

Drive through simulation and 3D views

Once your design is complete, view a three dimensional drive-through simulation of the road. Various parameters such as driver's eye height and sight distance are adjusted to provide a realistic simulation and to check stopping sight distance requirements.

Drawings and data exchange

Plots of profile, cross sections and plan can be produced on a variety of plotters and printers. Drawings can be saved in PICT or DXF format. Terrain and/or design data can be exported in 3D DXF, MOSS GENIO, CLIP III, CivilCAD ASCII, GDL, Quickdraw 3D, Quicktime, PICT and text formats.
