40 Support Required Saving lives through accident research! The percentage of registered cases notified is still low. We hope to receive notifications for all cases in the future. Access to FIR copies of all the accident cases registered in all police stations governed by Accident Police Stations in whole of Jaipur city (to get detailed summary of accidents). Official letter to grant JPRI access to CCTV footages of accidents which would help in improving the research. We also hope to get on site crash investigation assistance from Police. 19 April 2017 Accident Research Study - Jaipur (East Zone) 40
