A DMAIC-based methodology for improving urban traffic quality with application for city of Montreal
Bibliographic record
Abstract
Traffic congestion is a severe problem in cities. Drivers spend hours going through the traffic. This results not only in driver fatigue but also vehicular emissions, noise and pollutants into the environment. Controlling the situation of congestion in cities is of vital importance to city transport organisations and traffic decision-makers. In this paper, we propose a DMAIC-based methodology for improving the quality of urban traffic. The proposed methodology comprises of three steps. In Step 1, we conduct a survey study to collect traffic congestion data in the city. In Step 2, DMAIC methodology is applied to analyse the survey data collected from Step 1. The techniques used are Descriptive statistics, Pareto analysis, Cause-Effect Diagram, Factor Analysis, and Control Charts (Individual and Multivariate). In the third step, we generate recommendations for reducing traffic congestion and ameliorating transportation service quality in cities based on results of Steps 1 and 2. The proposed work is novel and has practical applicability in managing the situation of traffic congestion in cities. An application of the proposed approach for city of Montreal is provided.

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.
