Spatial analysis of the main road network in Al Zubair city using GIS

Abstract

The research aims to analyze the main road network in the city of Zubair through a network analyst after building a non-formal personal database that is compatible with the spatial analysis tools available in geographic information systems. The most important is a topology correction to avoid intersection between network lines and their mismatch, then building a network after entering the metadata, the most important of which are direction of travel, speed and time period.

Two sites were chosen to conduct the spatial analysis of the main road network in the city of Al-Zubair, namely the Civil Defense and Al-Zubair Hospital, as two hypothetical accidents were assumed to conduct the analysis of the shortest path (or what is known as accessibility) and the scope of service to know the areas served according to time periods and longitudinal distances determined by the road network.

Geographic information systems have shown high efficiency and ability in determining the shortest path and service area, and highlighted the need to establish two civil defense centers in hard-to-reach areas in the event of a fire within a period of time that reduces the scope of the expected damage, and they are Al-Shuhada neighborhood and Al-Marbad.
