This paper analyses vehicles with frontal impacts in the RASSI database to determine the crash severity, occupant restraint use and injury severity involved. 796 vehicles with single-event frontal impacts were considered. The vehicle types involved were distributed between personal "passenger vehicles" (cars/SUVs/vans), 37%; heavy trucks, 23%; motorised two-wheelers (M2Ws), 24%; buses, 14%; and "other" (auto rickshaws, bicycles, tractors and unknown vehicles), 2%. Seventeen percent (17%) of vehicles experienced crashes with delta-V greater than 48 kph (30 mph). The proportion of high delta-V crashes is greater than seen in the US National Automotive Sampling System (NASS). M2W riders had the highest risk of sustaining at least one AIS3+ injury (61%), while bus and heavy truck occupants had the lowest risk of AIS3+ injury (4% for both groups). Occupants in passenger vehicles sustained primarily AIS3+ head, thorax and lower extremity injuries, while M2W riders sustained a greater proportion of AIS3+ head injuries and fewer thorax injuries.

This paper describes the characteristics of single vehicle car crashes on Mumbai Pune Expressway. A total of 404 crashes were investigated on MPEW between the period October 2012 till December 2014. 22% of these investigated crashes were fatal whereas 21% were serious injury crashes. Out of 404 crashes, 101(25%) were single vehicle non pedestrian car crashes that do not involve other vehicles or pedestrians as colliding partners. 84 (83%) crashes out of these 101 single vehicle non-pedestrian crashes were databased in the Road Accident Sampling System-India (RASSI) and are considered for in-depth accident analysis in this paper. A significant percent of crashes on MPEW are single vehicle non-pedestrian car crashes and hence it is necessary to understand the characteristics of these crashes.

A research report, based on the two years of in-depth accident study on the Mumbai-Pune expressway, was submitted to the Additional Director General of Police, Traffic (ADGP-Traffic). The report aims at listing the contributing factors leading to accidents and injuries separately, and also ranking them on a scale of priority to mitigate accidents and resulting injuries alike.
In India, 1 in 20,000 people die and 12 in 70,000 people sustain serious injuries every year due to road accidents. A significant portion of these crashes and injuries involve motorized two-wheelers (M2Ws). Researchers from JP Research India (JPRI) have been conducting in-depth accident investigation on National Highways in South India for the last few years. This paper presents injury findings relating to M2W crashes.
This paper outlines a new, "Venn diagram" based, methodology aimed at identifying the contributing factors for accident causation and the resulting injury causation. The methodology was applied to 214 accidents on the Mumbai - Pune expressway. Factors contributing to accidents and injuries were addressed. The major human factors influencing accidents on this roadway were speeding (30%) and falling asleep (29%), while injuries were primarily due to lack of seat belt use (46%). The leading infrastructure factor for injuries was impact with a roadside manmade structure (28%), and the main vehicle factor for injuries was passenger compartment intrusion (73%). This methodology can help identify effective vehicle and infrastructure-related solutions for preventing accidents and mitigating injuries in India.
A research report, based on the one year in-depth accident study on the Mumbai-Pune expressway, was submitted to the Additional Director General of Police, Traffic(ADGP-Traffic) and was shared with media on a press meet. The report gained good exposure because of its unique approach of listing the contributing factors leading to accidents and injuries separately, and also ranking them on a scale of priority to mitigate accidents and resulting injuries alike.
This paper describes key features of the India-centric in-depth accident data collection methodology RASSI, developed by a consortium of vehicle manufacturers and researchers, with support from the police. RASSI uses established techniques to ensure it is compatible with crash studies in countries such as the USA, UK, and Germany while addressing issues unique to India. The paper also offers findings from the study of a total of 377 accident investigations carried out in Coimbatore District (Tamil Nadu, India) over a period of two years (2011-2013) involved analysis of 150 fatal crashes (with 167 rider/occupant and pedestrian fatalities), 147 serious-injury crashes (219 injuries), 45 minor-injury crashes (65 injuries), and 35 no-injury crashes.
Annual report explaining the usefulness and significance of collecting in-depth accident data and throws light on the existing limitations and a few suggestions to overcome the limitations.
This paper describes the methodologies used for in-depth accident data collection for the RASSI database. Characteristics of fatal accidents are also discussed which is based on a total of 167 cases investigated in Coimbatore District (Tamil Nadu, India) during a period of one year (2011-2012). A case study was also provided for a better understanding of the working methodologies.
This paper highlights the processes developed under RASSI to investigate on-site crashes and collect quality accident data suitable for detailed analysis to improve the safety of Indian highways and automobiles for all road users.
