The physical cost of these hardware platforms makes eld testing prohibitive, and the cost of collecting training data limits the size and diversity of this data. Autonomous driving simulation is a promising solution to address both of these challenges because it eliminates the need for a physical testing environment and because it oers environments that are congurable and diverse. However, most autonomous driving simulators are not fully useful for algorithm validation because they lack full integration with fundamental autonomous driving capabilities and because their sensor data is limited in functionality. In this work, we develop and present a simulation-based platform for testing and validation of autonomous driving algorithms that combines an open-source autonomous driving simulator (CARLA) with our existing autonomous driving codebase. Specically, we describe our software contributions to this platform, including simulated proprioceptive sensors and ground-truth LIDAR road information, and we demonstrate how we used the platform to validate both fundamental autonomous driving capabilities and a point-to-point navigation algorithm in simulation. We also describe how our platform was used to both develop and validate an approach to dynamic obstacle avoidance, a new capability in our codebase. Our platform is a capable tool for both validation and development of autonomous driving algorithms, although open directions remain in the areas of simulator sensor realism and runtime efficiency.by Rohan Bandopadhay Banerjee.M.
