KeyPOST is the structural design program to enable users to design sign
installations and also to test them, using current standards, against the
effects of wind loading and stability. KeyPOST calculates the post and
foundation requirements for a given sign installation. KeyPOST has Passive
Safety built in and complies with harmonised European standards such as BS EN
12899-1:2007 and its UK National Annex, and also the more complicated BS EN
1991-1-4:2005 Eurocode.
Graphical design tools allow signs, posts and foundations to be easily chosen
from a template library and arranged as required. Using the ‘AutoPost’ feature
valid structural arrangements are suggested, from which the most suitable
arrangement can be selected. Signs can also be imported from the market leading
sign design program KeySIGN.
A comprehensive report detailing the proposal and calculated results in full can
be generated. This includes diagrams, a summary of the proposal properties and
all the elements in the assembly as well as a comprehensive list of testing
results with passes and fails clearly indicated. |

KeyPOST in Detail |
|

|
|
|
Sign Selection |
|
Complex Sign Arrangements |
|
|
|
|
Signs can be selected from generic shapes and the required dimensions entered,
or fully coloured sign face designs can be imported from KeySIGN. Selected sign
arrangements show in design mode and this view is seen all the way through to
the output report. KeyPOST accommodates literally ANY combination of signs and
sign shapes, for example TSRGD Diagram number 2403.1 Village Boundary signs. |
|
|
|
Any number of signs can be added to the posts and the weight of each and offset
from the supports can also be specified, allowing the inclusion of Variable
Message Signs. This allows for ‘what if’ scenario testing perhaps to check
whether small additional or temporary signs can safely be added to an existing
sign installation. The graphical, drag-and-drop interface shows all objects

Graphical Method for Determining Wind Loading |
|
Post Manager |
|
|
|
|
The Site or ‘Environs’ wizard allows for the wind pressure to be set for any
sign installation, implementing the latest National Annex to BS EN 12899-1:2007,
and also the more complicated BS EN 1991-1-4:2005 Eurocode where appropriate.
The location can also be selected on a wind map. This sets the general expected
wind loading for a region or Local Authority area, but specifics site conditions
can then be fine tuned as necessary to take into account, for example, local
wind funnelling effects or significant orography (hilly!). |
|
|
|
Manufacturers’ data is specified in standardised XML format and can easily be
imported as new types become available. Suggested designs can be restricted to a
particular manufacturer, post type or material, or to Passively Safe supports
only (or any combination and/or number). |

Automatic Suggested Installation Details |
|
Traffic Light System for validity of design |
|
|
|
|
KeyPOST will suggest a range of valid post and foundation details, depending on
selected criteria, for example if a planted foundation is required to clear
footway services, or if the number of posts must be specified. Each suggested
design can be viewed graphically, and the full details of each examined until
the final design is committed. |
|
|
|
Any manually created design is automatically checked and pass or failure of each
criteria is shown in a simple green/red light system (shown lower left in this
image). Sometimes only a subtle tweak such as swapping from one post size to
another will cause all of the lights to go green, indicating structural validity
of the design. |

Full, Transparent Output |
|
Comprehensive Reporting |
|
|
|
|
A detailed report is available for any design. This is fully transparent, with
all calculations and assumptions made clear so that any design can be checked
for accuracy and suitability. This indicates clearly all passes and failures of
any aspect of each proposal (allowing substantiated rejection, for example, of
proposals to add additional signs to existing installations). |
|
|
|
The full report can be saved as PDF and printed for inclusion with other
contract documentation and sign schedules. This includes full graphical
representation of each proposal with fully dimensioned front and side elevations
automatically generated. Details for each sign, support and foundation are
included individually in tabular form. |

KeyPOST is backed by Key Traffic Systems’ full range of support services,
including training, support, user group meetings together with Autodesk product
and hardware sales. |
