KeyROADWORKS provides an extensive range of drawing tools to create Temporary Traffic Management (TTM) scheme designs in accordance with the Traffic Signs Manual, Chapter 8 Parts 1 and 2, 2009. A comprehensive library of pre-drawn traffic signs is also supplied, with further routines for drawing road markings and placing general traffic management equipment symbols.

Layouts can be created in the traditional wallpaper style diagrammatic scheme, or based on Ordnance Survey mapping. On real mapping an ‘intelligent’ signing corridor object allows for designs to be re-used, and drag-and-drop edited to suit any road, and is also ideally suited to rolling works such as barrier maintenance, as the datum (start point) of the works can easily be moved along the road corridor with signs, placed at specified distances, moving along automatically.

Quantities of road marking, signs and other symbols are extracted from the drawing automatically and tabulated to ensure accurate estimation, and provide equipment picking lists for the teams on-site. 		 

     
  KeyROADWORKS Highlights  
  Professional CAD based design: Temporary Traffic Management layouts can be designed quickly using a wide range of tools, backed up by the industry standard AutoCAD.   Re-usable Zone Based Designs: Dynamic Signing ‘Corridor’ object allows for designs to be re-used. Whole signing layouts can be drag-and-drop edited to suit different road layouts.  
  Intuitive Commands: Easy to use routines for positioning signs and symbols are provided. Local works and big Trunk roads can quickly be drawn up.   Complete Workflow Solution: Quantities of signs, road marking text and lining can be determined automatically. These are tabulated to detail Bill’s of Quantity and equipment pick lists.  
  Site Installation Tool for Temporary Signs: Includes Ballast Calculator module for temporary sign support design. Calculate required ballast loading to local conditions.      
     
  “The drawing production routines and sign
libraries have increased productivity and
inspired the development of more complex yet
more user friendly drawings.”

  KeyROADWORKS in Detail      
  Comprehensive Sign Library and Sign Face Design Tools   Corridor Based Design  
 
KeyROADWORKS includes a huge library of signs, currently over 350 (TSRGD 2002) standard signs and permitted variants. These can be selected from a categorised selection of thumbnail menus.
 
An intelligent signing corridor object allows designs to be repeated, and drag-and-drop edited to suit specific local circumstances. This is also ideally suited to rolling works as the datum (start point) of the works can easily be moved along the road corridor – all signs are positioned at specified distances from the datum and are automatically repositioned to remain as such. Complete TTM schemes can be worked up quickly, leaving more time to consider the finer points of the design.
 
         
  Zonal Signing Corridors Allow for Re-usability   Linear Signing  
 
The parameters of the Signing Corridor itself can easily be configured allowing quick re-positioning of whole strings of signs, just by dragging-and-dropping the datum point. The corridor itself is modelled on a natural, curve fitting Spline which can easily be ‘grip’ edited, if it is needed, on different road alignments. This allows for example the approach signing zone, which is often the same for many schemes, to be re-used no matter what the road geometry.
 
The Signing Corridor model also accommodates lines of signs or other objects designed to control the flow of vehicles (see configuration screen below). Lines of cones, for example at 1 metre intervals, tapered across a carriageway can quickly be added, perhaps also with an additional symbol such as a cone-top flashing light at a different interval included. This ‘Control Alignment’ tool can also be used for example to show the line, position and number of workforce protection barriers, including crash attenuation starting block.
 
         
  Linear Signing – Flexible re-usable Design   Diagrammatic and O.S. Map Based Designs  
 
‘Control Alignments’ (lines of objects to control the flow of vehicles) are added to the Signing Corridor by way of various parameters. The parameters can easily be changed and the drawing is automatically updated to reflect different settings, including for example distance from datum, and offset from the edge of carriageway at each end. Shown here are the values for a taper – a line of cones at 1.00 metre intervals going from 10.55 metres (offside edge of carriageway) to the start of a 3.65 metre single running lane through the work zone. Longer term works may include workforce protection of some kind, and an edge of carriageway road marking can easily be added.
 
KeyROADWORKS, in combination with AutoCAD can be used to create professional designs on either the traditional, simple diagrammatic layouts, often still appropriate for straightforward or local works; or on full 1:1 scale Ordnance Survey Mastermap.
 
         
  Professional, Presentation Quality Design   Quantity Take-off  
 
KeyROADWORKS can be used to create easy to read designs, supporting on-site operations. This also allows for professional, presentation quality designs to be drawn up to support the tender process ensuring that you can win those contracts.
 
Quantities of road marking, signs and other symbols are extracted from the drawing automatically and tabulated to ensure accurate estimation, and provide equipment picking lists for the teams to take out on-site.
 
         
  3D Design and Safety Audit   Ballast Calculator  
 
A driver’s eye view can quickly be shown, to check sight lines and other aspects of a design for Safety Audit. This harnesses the power of 3D design in the CAD environment, whilst making the process simple and intuitive.
 
Included with KeyROADWORKS is the Ballast Calculator module for temporary sign support design, which allows for local wind conditions to be considered. Short term works or Long Term Exposed, wherever in the UK, KeyROADWORKS will determine suitable ballast loads to avoid worst case scenarios such as the sign assembly sliding when wind forces apply to the rear of the sign. Different mounting criteria, ballast position and coefficient of friction can all be set as required.
