Network Analysis and its Applications in Urban Planning

The concept of the network evokes the concept of system. A network is a set of points and lines that carries energy and resources. The points are the places at which sources are injected to lines or collected, for example, schools, terminals, reservoirs, and so on. Lines are connections in the network that connect the points. The purpose of this paper is to illustrate three major applications of network analysis in urban planning. Through network analysis, the best route, which is generally the closest route between two points, can be achieved to reduce travel costs. Or, it is possible to select the nearest center from among the rescue centers, in order to help the injured in shortest possible time, and to prevent further damage to life and property. Also, through allocation of resources, it is possible to make a more appropriate and rational planning for citizens' access to public services and realization of social justice.
