Each route in the provided routes file is interpolated into a dense sequence of waypoints and individual junctions are sampled from these based on change in navigational commands.
Additional scenarios are densely sampled in a grid centered at the locations from the [reference scenarios file](https://github.com/carla-simulator/leaderboard/blob/master/data/all_towns_traffic_scenarios_public.json). More scenario files can be found [here](https://github.com/carla-simulator/scenario_runner/tree/master/srunner/data).
