  • TRIPP Conference in IIT DelhiCharacteristics of Single Vehicle Passenger Car Crashes on the Mumbai-Pune Expressway

    Authors: Balakumar Selvaraj, Vernon Chinnadurai, Rohan Govardhan

    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.

    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.

    Authors: Muddassar Patel, G SanthoshKumar, S Balakumar, M Bhuvanesh, Murtuza Painter, Ajay Patel, Ravishankar Rajaraman, Ahamedali Hassan, Jeya Padmanaban

    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.

    Authors: N Rameshkrishnan, A Sathyakumar, S Balakumar, Dr. Ahamedali M. Hassan, Ravishankar Rajaraman, Jeya Padmanaban

    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.
