Roads

Road design program
Is a comprehensive road design program that provides interactive embankment design and area calculations for urban streets, single and dual carriageway roads, freeways, airports, parking areas, railways and dams. It also includes additional functions such as the regression analysis of the alignment of existing roads.

Roads Features



HANDLES MORE THAN 250KM OF ROAD EFFORTLESSLY
The Roads module has been used to design single or dual carriageway roads of over 250km in length. It has also been used to design split horizontal and vertical alignments where roads have been built through difficult terrain.

GRAPHICAL OR SPREADSHEET DESIGN TOOLS
Quickly switch between alignment views or data sheet information using tabs on the same page and access all the relevant design tools and functions.

HORIZONTAL AND VERTICAL ALIGNMENT ACCORDING TO TRH17 & SUPER ELEVATION
While designing the horizontal and vertical alignment the program will warn the user when design criteria are exceeded. Automatically design the super elevation using TRH17 standards or custom standards including reverse, compound and broken-back curves.

You can also calculate super elevation and run off lengths according to horizontal curves and specified design criteria.

The vertical alignment function allows you to display up to 20 profiles such as the ground line at centre line plus the left and right road reserves while the grade envelope will guide you according to the design criteria. The stake position is dynamically displayed on the plan view so you know exactly where the horizontal curves are.

INTELLIGENT PROFILE SELECTION FOR MULTIPLE CUT AND FILL CONDITIONS
Edge conditions, drainage and batter slopes are automatically adjusted on road profile according to your specified cut and fill conditions. This means that you can automatically have different cut/fill slopes according to the depth/height of cut or fill.

TRH4 PAVEMENT CLASSES AND PAVEMENT DESIGNER
You can create various pavement libraries containing several manually defined pavement designs. These files can then be used throughout an organization. The pavement symbol can be automatically generated on cross section plots.

STANDARD SABS927 KERBS WITH KERB EDITOR FOR CUSTOM KERBS
The kerb editor allows you create a kerb group file containing one or more kerbs. Each kerb contains cross sectional geometry data and quantities data. Kerbs can be specified in the Edge level specifications, which are then stored as part of the batter layer. You are then able to calculate kerb quantities and plot cross sections that includes the kerbs.

MINIMUM SIGHT DISTANCE CHECK WITH FULL 3D ANALYSIS
This function will calculate the areas along the road alignment where the driver cannot see the specified object over a specified minimum sight distance. These areas will be marked in the specified pen colour on either the vertical, or horizontal alignment. This includes when the driver’s sight is obstructed by vertical curves, horizontal bends, cuttings and drains or a combination of.

The program will use the batter cross sections for sight checking. If the offset of the toepoints are less than the specified road reserve, then the program will include ground points beyond the toepoint and up to the road reserve width when doing sight distance checking.

CLIMBING AND AUXILIARY LANE ANALYSIS WITH SPEED PROFILING
Precise control of the road edge levels allows you to apply complex super-elevation conditions and it makes provision for changes in lane widths for climbing lanes or auxiliary lanes. You can create auxiliary lanes by specifying the lane width, start and end position, the taper lead-in and lead-out length and the layer works template to be applied. Automatically suggests climbing lanes based on Speed Profile analysis of the vertical alignment.

ROAD REHABILITATION FUNCTION
You can use this function to extract the theoretical alignment of a surveyed road (DTM). With the Road Rehabilitation function you can pick up a horizontal alignment from CAD lines and arcs, or by specifying two points on each straight and one point on each curve. Once you have a horizontal alignment, the routine will automatically extract a theoretical vertical alignment (vertical PI points, curves and straights) as well as the super elevation from the survey.



 


ROAD QUANTITIES WITH LAYERWORKS
Road quantities are calculated from cross sections using the end area method, adjusted by a compaction factor and topsoil stripping. The results include:
  • Unadjusted cut and fill volumes
  • Adjusted cut available for fill
  • Adjusted excess cut
  • Adjusted fill shortfall
 
  • Topsoil stripping
  • Bank areas
  • Topsoil cover

The module further supplies COLTO slope finishing quantities. Layerwork volumes can be calculated and will yield the total volume for each layer as well as layerwork volumes for each layer in cut and fill, and the preparation area for each layer in cut and fill.

CREATES LAYOUT PLAN, LONG/CROSS SECTION WITH CROSSING SERVICE
Crossing services from sewer, storm, water modules and other services can be displayed when designing vertical alignment. These services can also be viewed on your cross section editor and displayed on long and cross section production drawings. While designing the Vertical alignment, additional information on vertical curves and grades are dynamically displayed in an information box in the top of the window as you move.

SPECIFIYING EXTRA EXISTING AND ADDITIONAL SERVICES
Create additional services such as telecommunication ducts, electrical cables etc. These services can then be displayed on the plan layout and as crossing services on long sections and cross sections and viewed/edited in spreadsheet form.

FULL WORKING PLANS, LONG/CROSS SECTION WITH CROSSING SERVICES
Sections are stored in up to 128 layers. Keep track of construction progress by recording each month’s results in a separate layer. Calculate cut and fill volumes between any two layers with topsoil stripping and bulking or compaction factors. Extract up to 20 long sections from any of the 128 layers to define ground lines, intermediate or hard material lines at user defined offsets on long section drawings.

CREATE MULTIPLE DESIGN CODES
You can create multiple design codes for horizontal and vertical alignment as well as super-elevation and simply load the one you require for a particular job. Roads will determine the horizontal curve radii, vertical curve lengths and super-elevation based on the design criteria for the design speed.

HANDLES MULTIPLE BACKDROP DISPLAYS OF HUGE SIZES
Display a bitmap showing the natural features, the cadastral layout drawing or the site contours while defining the horizontal alignment graphically by indicating the position of the HPIs. Once the HPIs have been defined you can drag them to modify the alignment. Route planning has never been so easy.

RENDERED 3D VIEW
'Drive' down the completed road in a rendered 3D view to check for blind rises and other anomalies (requires Survey & Terrain module). The program uses a 3D algorithm that takes vertical curves, horizontal curves and cross sections into account.

ROAD EXPERT
The Road Expert will keep track of the design progress and if any changes are made it can automatically update the design. This allows you to instantly see the results of your changes.

CREATE PRODUCTION DRAWINGS AND PLANS
Production drawings such as plans, cross sections and long sections with title blocks and company logos etc can be created with no or little CAD editing. The layout of production drawings are completely customizable according to your specific company standards. Crossing services from the other modules can also automatically be displayed on long sections and cross sections. These drawings will automatically update as you change your design.

FULLY COMPATIBLE WITH DWG AND OTHER INDUSTRY PACKAGES
Knowledge Base is a founder member of the Open Design Alliance and, as such, our inside knowledge of the DWG drawing structure ensures high compatibility when loading and saving DWG and DXF drawing formats, including Paper Spaces. In addition we also support loading of Caddie CEX, Arcview SHP, Microstation DGN and Ultimate CAD UCX files. This gives you unprecedented flexibility to move between drawings without having to worry about incompatibilities and data exchange problems.
