Accuracy Analysis of Short-term Traffic Flow Prediction Models for Vehicular Clouds
Bibliographic record
Abstract
Vehicular Clouds introduces a new paradigm that addresses and potentially enhances underutilization of on-board computing resources through aggregation to solve several computational tasks in Intelligent Transportation System. The most challenging issue in Vehicle Cloud is the task allocation among the dynamically changing amount of available resources. For further research towards this issue, a realistic road traffic system models which could generate traffic flow with high accuracy must be designed. In this paper, we conduct a study on short-term traffic flow predictions for our envisioned road traffic prediction system. Five prediction models, including double exponential smoothing (DES), seasonal autoregressive moving average (SARIMA), K-nearest neighbor (KNN), back-propagation neural network (BP-NN) and support vector regression (SVR), are implemented. Then, three different error metrics are used to evaluate the performance of these models. Finally, the results shows that SARIMA and BP neural network are two precise and stationary prediction models and thus are the best candidates to be embedded in an road traffic load prediction system.

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.
