It attracts many people from different parts of the city and its suburbs, owing to its location 
and transportation links. T.Nagar has the highest commercial catchment population when 
compared with other commercial centers of the city like Adyar, Nungambakkam, 
Purusawakkam, etc. 
Commercial activity has spread over the years on all the major roads, in a linear pattern. Now 
it is slowly encroaching on the by lanes of the major commercial streets. Single storey shops 
have given way to multi storey shopping malls, but with little change in the infrastructure. 
This sketch uses the same graphical representation for Ranganathan Street, employing the 
personal space bubble and the moving space bubble. There are no sidewalks. Vehicular 
movement is restricted so the entire stretch is used by pedestrians. 
The entire sidewalk is taken up by 
hawkers. Unauthorized parking of two 
wheelers and auto rickshaws also push 
the pedestrian farther out into the 
vehicular carriageway.
