Nearly 1.2 million people die worldwide as a result of road traffic collisions every year. Over 1.2 lakh of people are killed every year on Indian roads. The economic loss due to road accident is over Rs.75, 000 crores per annum in India by 2009. Road accident scenario in the State of Tamilnadu is also very grim; nearly 12000 people are killed in about 60,000 accidents annually. In Chennai City there are 35 fatalities per 10000 vehicles which are 2.5 times higher than the national average. Hence it is imperative to study the root cause of accident occurrences by developing a macro level simulation model for ensuring the road safety. In this study an attempt is made to identify the various causes for road accidents in Chennai City and to develop a System Dynamics simulation model as conventional model lacksin reducing accident severity. Systems approach is not a mere theory, but a way of thinking and practical philosophy of solving problems. System Dynamics is a methodology, whereby complex, dynamic and non linear interactions in social systems can be understood and analyzed and new structures and policies can be designed to improve the system behavior. As the road accident prediction studies involve various complex systems namely the human, road, vehicle and all other environmental factors, it is vital to develop dynamic simulation model to understand the interactions between the various complex systems. This would evolve sustainable solutions towards ensuring road safety. In this work the System Dynamics Simulation software namely STELLA is used. Accident data pertaining to training given to the public, transport, highway and police officials are collected from Government sources. The developed model is calibrated for various scenario options ranging from best policy to worst policy. The model has also been validated with the real world accident records.
