Optimal Modelling of a Transportation Network at the Level of Cluj County by Using ArcGIS Network Analyst
Abstract
This paperwork presents a model of transportation network which uses a package of programs allowing the creation, processing, integration, analysis and posting of geographical data at various levels. ArcGIS was used, extension ArcGIS Network Analyst, with which the area of influence of an economic objective on any location from the map may be identified, representing the network, as well as the data base obtained following the Digital Romania National Project. In the model created by the road network 16 points of interests were added on the map of Cluj County, divided into two themes: Agricultural holdings: Aghireş, Baciu, Beliş, Berind, Floreşti, Huedin, Steluţa; Livestock holdings: Apahida, Cojocna, Copăceni, Dej, Iclod, Floreşti, Răscruci, Someşeni, Tureni. The modelling of transportation network from this paperwork contains three phases: a) The travel of path through all points of interest having as starting and return point the city of Cluj-Napoca without barriers and without the optimization option; b) The introduction of several restrictions on the previous path; c) The optimization of path with barriers, as well as without them.
