- Used Pybullet software to simulate multiple vehicles colliding to extract the values of Energy Dissipated after Collision
- Modeled for two different types of collision - Cascading Collision and Direct Collision
- Developed a pipeline of mass, angle, velocities of multiple vehicles colliding to get end-to-end simulation plus results out
- Extracted over 150 variant collision data for Cascading collision and 200 more data for Direct collision and fit a neural network to predict the dissipation energy released for all the vehicles.
- Map the crash severity to the predicted energy dissipation from the model.
