Investigating Safety of Evasion Maneuver Choices by Human-Driven Vehicles in Response to High-Density Truck Platoons Near Freeway Diverging Areas
Bibliographic record
Abstract
High-Density Truck Platoons (HTPs) introduce new safety challenges for Human-Driven Vehicles (HDVs) near freeway diverging areas due to their extensive spatial and temporal occupancy. When navigating around an HTP, HDVs approaching off-ramps face two Evasion Maneuver Choices (EMCs): Platoon Front Overtaking (PFO) and Platoon Back Evading (PBE). To evaluate EMCs safety, we conducted driving simulation tests in scenarios with short, medium, and long distances of releasing. We used trajectory data to derive Anticipated Collision Time (ACT) and other behavior and safety metrics. A generalized extreme value (GEV) model based on ACT was utilized to evaluate the crash risk during the lane-changing process to evade the HTP. The results indicated that in the short scenario, the crash risk for PFO is higher, while in the medium scenario, the crash risk for both ACPs is roughly equal. The long scenario sees PBE as the riskier behavior. In addition, the crash risk notably decreases when transitioning from short to medium scenarios, regardless of the selected EMCs. These findings have important implications for the development of lane-changing assistance devices for HDVs and safety-oriented lane management strategies near freeway diverging areas.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
