Some survey reports are available from few states and remaining should to be carried out to get Uniform National Data Index. Suggestions are invited from the exports of this field.
When I was working at Mepco Schlenk Engineering College, we made an attempt to get the data on Road Accidents, in a very small scale. That was for within Virudhunagar District only. We obtained data from few of the local sources:
1) Local police station
2) Local Hospitals
3) Local schools and colleges
4) An adverticement in the local cable TV network
5) Personal circulation of slips to students and staff
Thanks to Ms Neelima Chakrabarty ji and Dr Ravindran ji for useful information on road accidents. In case of tractor we have more intention on off road accidents also in which village punchayat, local school and colleges and shop keepers including some personal circulations will be helpful in addition to recorded infomations..
