SATURN, through module P1X, also possesses powerful graphical display
capabilities for network, junction and matrix-based data. Junction details
including link and turn data may be shown at both individual junction and
network wide levels. The wide range of options available also allows for
on-screen cordoning, select link reassignments, GIS-style background displays,
animated queues, data editing and tree building.
The interactive and graphical facilities of PIX may also be used to “edit”
existing networks on screen and/or to build networks from scratch on the screen.
The latter function may use an existing bitmap file (e.g. a normal road map
which has been scanned) as the background and to “trace” the SATURN network on
top of it.
In a related fashion SATURN may be applied to the analysis of network-based data
which need not be in any way related to traffic assignment problems. For
example, data relating to accident rates per link, or the last dates of road
resurfacings stored, etc may be input and analysed.
Through its general matrix manipulation program MX SATURN offers a full range of
interactive matrix operations as required by standard transport planning
applications, e.g. matrix building, editing, factoring, furnessing, transposing
etc. It also provides easy transfer between SATURN and other transport and
spreadsheet packages.
