This book develops a Spatial Decision Support System
(SDSS) integrated with the use of Geographical
Information Systems (GIS) and the Global Positioning
System (GPS) to quantify the non differential GPS
(non-DGPS) dynamic positional accuracy of articulated
trucks travelling on the Irish public road network.
The system developed enables the GIS simulated
routing strategies and GPS tracked routes to be
assessed on a cost per kilometre (CPK) basis. The
CPK can therefore be used to determine the most
optimum route (on a costs basis) to be travelled in a
pre-planned manner. The DSS developed is a
combination of databases, user interfaces and
modelling components directed at solving a specific
problem. The GIS and DSS together combine to create
a Spatial Decision Support System (SDSS) to extend
the range of decision support through its ability to
define route selection and also the display of
spatial road vector data for the user interface can
greatly enhance the decision making process. Visual
Basic for Applications (VBA) was used to design and
create the DSS while the GIS provides the spatial
interface, database and route modelling component.
