Elements contributing tosustainable habitat
Density: It is the concentr tion of population, dwelling units, employment orany other variable over a specific area which can be either gross or net
Design: the street network which is pedestrian oriented rather than auto andwhose characteristics include side walk, inter connection with in the streets,number of intersection, pedestrian crossing, street lighting
Diversity:It is a measure ofv riety of l nd uses present in a given area onthe basis of floor area, employment and land area
Distance to transit: the average of the shortest street routes fromhome or work to the nearest rail stations and bus stopsDestination accessibility:the e se with which one can ccess thetrip ttr ction to both local (market) and regional (jobs) destinations
