CS513 CARLA runs
Recorded runs of the CARLA 0.9.16 driving simulator from the CSCI 513 group project. Each run has every tick of one drive: the static scene (roads, junctions, crosswalks, buildings, and parked vehicles), the ego vehicle, background traffic, pedestrians, traffic light states, and the ego's collisions and lane crossings.

town10-demo.jsonl.gz |
The run file: Town10HD_Opt, the ego driven by BasicAgent among 30 vehicles and 30 pedestrians, 4,714 ticks (235.7 simulated seconds). At 26.5 s the ego hits a bus and then waits behind it. |
town10-demo.rrd |
The same run converted for Rerun 0.38.1. |
The run file is gzip-compressed JSON lines, format version 1. The project repository documents the format and has the tools that record runs and convert them to .rrd.
