Study Area Description
The Besant Nagar area in South Chennai is the study area used to design this system and used to test this system.
The area had the following geographic coordinates:
| Longitude : | 80° 15’ 55” E to 80° 16’ 13” E |
| Latitude : | 12° 59’ 52” N to 13° 00’ 09” N |
The Besant Nagar area was selected because it has lots of streets and inter connected roads thus offering good scope for network analysis. Although, Besant Nagar has been used for this study, this system could be extended for the whole of Chennai city.
