A free plug-in for ArcGIS mapping program developed at MIT

Urban Network Analysis, is an open-source software released by MIT. Taking a cue from social networks and mathematical network analysis methods, the City Form Research Group's program calculates how a cities' spatial layout affects the way people will live in it.
It measures traits such as "reach, gravity, betweenness, closeness, and straightness," which, in laymen terms, express features such as the number of services, buildings, and resources within a certain walking distance, or the volume of traffic along sidewalks and streets. Designers can also assign characteristics to individual buildings, as well as track urban growth and change with analytic support for policy makers.
What this means is that city planners can look at their cities and see, for instance, that some neighborhoods are closer to jobs than others (the map at the top is the "reach" map for jobs in Cambridge, MA. Red means closer to jobs). Knowing this, planners might want to build transportation from green areas to red areas. It can also predict things like street traffic: Good to know if you want to create a commercial zone where you will need walk-in customers.
Until now, claims MIT, no free tools were available for city planners to tackle the tough computational challenges of characterizing the dense tangle of streets, buildings, and transport in modern cities. MIT hopes the UNA toolbox, an open-source plug-in for the ArcGIS mapping program, will enable urban designers, architects, planners, and geographers around the world to better understand how the spatial patterns of cities will affect the way people live and move around their urban environments.

  1. Hey Its really good job buddy you are giving the clear cut ideas on Social Network Analysis which has become the backbone of our society .
    Its also giving the opportunity to create communities and through this people are increasing the memberlist of their community
