This repository provides the Bench2Drive benchmark for closed-loop end-to-end autonomous driving, accepted at NeurIPS 2024 Datasets and Benchmarks Track. It includes a large-scale multi-modal dataset (up to 7.3TB) collected in the CARLA simulator, an evaluation suite with metrics like Driving Score and Success Rate, and baseline results for over 10 methods. The codebase is a hybrid of research data pipeline and application: the dataset generation and evaluation scripts form the core data_research component, while the B2DVisualize Flask app, scenario runner, and leaderboard evaluator provide application-like interfaces for interaction and reproducibility. Data lineage: raw simulation data (sensor recordings, ground truth annotations) is collected via data_collect.py, transformed into compressed archives with JSON manifests, and evaluated using the leaderboard pipeline that computes multiple ability metrics. The repository answers research questions about the effectiveness of end-to-end driving policies under diverse urban scenarios.
