Collision Avoidance System for Self-Driving Vehicles by Delta Autonomy, Robotics Institute, CMU. This stack was developed for my MRSD capstone project.
Our use-case involves an oncoming vehicle encroaching into the ego-vehicle's (heavy-duty truck) lane, on a two-lane countryside highway. The perception algorithms perform the detection and tracking of vehicles, and lane marking detection, using a sensor fusion of a monocular camera and RADAR. The prediction algorithms predict the trajectories of all vehicles in the environment including the ego-vehicle. Based on the predicted trajectories, the probability of collision, position and time-to-impact is computed. An evasive maneuver, such as steering or braking, is planned and executed to avoid or mitigate the crash. The project was developed in Carla simulator and ROS.

- Collisions detected in 90% cases with 80% accuracy, and mitigated in 60% cases via an evasive maneuver or braking strategy.
- Achieved mAP of 0.7-0.9 for object detection, lane detection with offsets less than 0.5m.
- Our tracking and sensor fusion pipeline achieved MOTA 75% and MOTP 85%.
- Prediction of trajectories of oncoming vehicles within an RMSE of 2m, and ego-vehicle within an RMSE of 1m, 2-3 seconds in future.
- The entire pipeline runs at 21-24 FPS along with a NVIDIA Titan V GPU.
- We also developed custom maps in RoadRunner and created collision scenarios in Carla.
- Developed a JavaScript based dashboard GUI interfaced with ROS in real-time.
This repository is only a collection of all the ROS packages developed by us. Feel free to raise issues and pull requests on the original repositories.
