# Traffic Accident Understanding on ACCIDENT Leaderboard (private) Source: [Traffic Accident Understanding on ACCIDENT Leaderboard (private)]() Collection index: [llms.txt]() Data updated: 2026-06-11T10:59:20.833Z Evaluation of models on the private ACCIDENT Leaderboard focusing on Traffic Accident Understanding, reporting metrics such as ACCS, C, T, S, and Private LB. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Traffic Accident Understanding | | Dataset (including any stated split) | ACCIDENT Leaderboard (private) | | Metric | C | | Unit | PERCENT | | Direction | Higher is better | | Results loaded | 8 of 8 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [C](): Higher is better; unit: PERCENT. - [ACCS](): Higher is better; unit: PERCENT. - [T](): Higher is better; unit: PERCENT. - [S](): Higher is better; unit: PERCENT. - [Private LB Score](): Higher is better; unit: PERCENT. ## Recorded results | Method | C | Result date | Report paper | | --- | --- | --- | --- | | Ours 32B (3-stage) | 59.94 | Not recorded | 6a191dafdbd7150506f82944 | | Ours 9:1 ensemble (32B type) | 59.94 | Not recorded | 6a191dafdbd7150506f82944 | | Ours + bbox snap (final) | 59.94 | Not recorded | 6a191dafdbd7150506f82944 | | Baseline A | 58.07 | Not recorded | 6a2a4144d33dfb23e783947e | | Baseline B | 58.07 | Not recorded | 6a2a4144d33dfb23e783947e | | Ours 235B (3-stage) | 57.03 | Not recorded | 6a191dafdbd7150506f82944 | | Three-stage pipeline | 50.57 | Not recorded | 6a2a4144d33dfb23e783947e | | Molmo-7B baseline | 29.3 | Not recorded | 6a191dafdbd7150506f82944 | ### Ours 32B (3-stage) C: 59.94.
