The UK's leading traffic sign design software comes with built-in state-of-the-art structural design and doesn't need an expensive CAD system.

SignPlot is the only system to fully automate the layout and spacing rules of the Traffic Signs Regulations and Traffic Signs Manual, including TSRGD 2002 & 2011 and the Area-wide authorisations for England.

SignPlot 3 adds to this an amazing new tool that automates pretty well everything about direction signs: destinations, mileages, panels, patches, symbols, arrows, route numbers and any regualtory or warning signs shown on them.

SignPlot makes sign design quick, accurate, colourful and economical for both new and experienced designers.

Implements structural and passive safety standards

Implements structural and passive safety standards


DfT design standards have brought consistency to the presentation of information on road signs, but have also made the design task challenging for anyone unfamiliar with the complex layout and spacing rules.

The automation that SignPlot provides enables easy construction of everything from the simplest flag-type, to the most complex gantry-mounted lane indication sign. It helps avoid sign layout errors, whilst minimising design time. Software training costs are reduced and productivity is improved. SignPlot displays a message if it spots a potential mistake and offers to correct the problem.



Preview signs and symbols

Preview signs and symbols


SignPlot is supplied with library files containing accurate symbols and signs that scale automatically to the correct size for use on direction signs and parking plates. These are updated regularly generally in advance of new symbols being published by the DfT, as SignPlot is used by them to produce official documents such as the Area-wide authorisations to all English authorities.

SignPlot can be supplied with your logo and any tourist, public transport or other symbols specific to your area, or you can import your own bitmap images for use on signs.


Fast Performance and Editing

SignPlot permits signs to be designed in any order. Start with the text, or start with the road layout or symbols - the choice is yours.

As well as making sign creation quick and flexible, SignPlot really excels when changes are needed. If a junction type, route number, destination or even the size of the lettering is changed, SignPlot automatically rebuilds affected signs, incorporating the destinations and symbols of the original, and applying the relevant spacing rules.

Distances are aligned, character and word spacing is automatic, and panels or symbols can be added with only a basic knowledge of how a sign should look, so you only rarely need to know about 'stroke widths'. For more advance use, graphical drag and drop editing allows any sign element to be quickly repositioned.


Sign Manufacturing

SignPlot includes character and symbol outlines accurate enough for computer cutting of the actual sign face material, and provides for mounting and manufacturing margins to be added.

An economical and passively safe sign structure may be designed in the software: supports, foundations and (with an optional module) channel section spacing. SignPlot leads the way in implementing the 2007 revisions of BS EN 12899-1 and the passive safety standard BS EN 12767, and contains comprehensive data from all leading suppliers of supports and other sign components. It is certified for CE marking of traffic signs, which became compulsory on 1 July 2013. A separate leaflet describes SignLoad, the structural design module built into SignPlot.


Data Management and Storage

A typical sign requires only a few kilobytes of disk space, so that many thousands may be stored on the smallest of computers, and complete schemes may be easily emailed. This eliminates the need to archive old drawings, providing easy access to every sign in an authority. SignPlot's search facility allows you to quickly find signs that contain a particular word or symbol.


Compatibility with Other Systems

SignPlot is one element of the UK's most comprehensive range of traffic signing systems. It links to SignMap for planning signing schemes and recording inventory information, and with SignRoute for generating signs from a signing network. The link with ParkMap, the leading system for making and managing traffic orders, enables parking signs to be produced automatically and displayed on the map.
