Strategies for both perception and decision making can be studied in simulation first, before deployed to real world systems, saving on time and costs. Despite significant progress on the development of sim-to-real algorithms, the analysis of different m... | [] | null | null | 2011.08985 | title_judge |

Our approach relies on using lane centerlines captured in rich maps of the environment to generate a set of proposed goal paths for each vehicle. Using these paths – which are generated at run time and therefore dynamically adapt to the s... | [] | null | null | 2009.04450 | title_snapshot |
