Transportation data model implementation for Iranian roads network

  rk needs essential information about the transportation system(s) for their own routing, planning, business operations, and other needs. As such, the needs of these users must be considered as part of the basic infrastructure model. While the breadth of the field of transportation prevents a comprehensive catalog of objects from being assembLED that would meet the needs of all user groups, those elements that are common to many transportation GIS users have been identified, and are presented here.[1]

The ArcGIS?Transportation Data Model is designed as an 揺ssential?data model that provides a context within a GIS that can quickly and easily accept the input that a wide range of users need in order to accomplish their transportation management goals. The 揺ssential?data model can be seen as the intersection of many other models. This model is specified in an industry-standard modeling notation called the Unified Modeling Language (UML), and is intended as a starting point for structuring transportation data. The UML model is a detaiLED view of the design; it provides data types, relationships, and other details. This is the view of the database design that can be used to create a geodatabase. The second element is a logical data model view that presents the basic structure of the UML model. The third element is a set of data used to demonstrate the efficacy of the ArcGIS?Transportation Data Model. This data set is composed of public domain, transportation related data that may be freely used to support specific applications. [1] [Page]

The ArcGIS?Transportation Data Model can help a user or an application development team to generate a geodatabase. In general, the geodatabase is a logical extension of the relational databases that have been long accepted in GIS applications. Geodataba
