Estimating lateral placement and lane indiscipline of urban mixed traffic of a developing country: an ANN-assisted approach
Bibliographic record
Abstract
Information on lateral placement and lane indiscipline is useful in simulation of a mixed traffic stream and in identifying the distressed portion of a pavement. Despite this utility, inadequate investigation has been made to estimate the lateral placement of vehicles under prevailing traffic conditions. In a typical mixed traffic situation, vehicles having different static and dynamic characteristics take any lateral gap across the carriageway left empty by other surrounding vehicles and move in an untidy manner. This leads to variation in lateral placement of vehicles, governed by the subject vehicle type. This paper explores the potential factors that influence lateral placement of vehicles and presents an artificial neural network (ANN)-based approach to quantify lateral placement and lane indiscipline in the context of undivided urban roads. Further, sensitivity analysis revealed how different traffic parameters like traffic volume, traffic composition, and directional split influence lateral placement and lane indiscipline within each vehicle category.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
