DTC-FM: Expert-Annotated UAV Traffic Conflict and Surrogate Safety Dataset
Listed in Aperta Turkey Open Archive
This dataset ( FME-V ) contains 2,510 expert-annotated traffic interaction and surrogate conflict events extracted from high-resolution UAV video trajectories across 65 intersections (collected under the TÜBİTAK 123M640 / KARDS project) .
Description
It is designed to train, validate, and benchmark classification models (such as the Dual-Threshold Controlled Filter Model - DTC-FM ) aimed at mitigating false alarms in Post-Encroachment Time (PET) and trajectory-based surrogate safety analysis .
The dataset includes:

- Kinematic & Geometric Features: Core and derived trajectory-based metrics (e.g., , , , , velocities , acceleration , conflict angle , and total object count ) . · Interaction Class / Sequence: Road user interaction types provided in native categorical (character/string) format representing vehicle and vulnerable road user (VRU) encounter sequences.
- Ground Truth Target ( ): Expert consensus binary labels ( 1: Surrogate Conflict , 0: Normal Interaction / Undisturbed Pass ) established through deliberated expert consensus .
