Abstract

fetched live from OpenAlex

Traffic loading for pavement deterioration should be modeled as a dynamic indicator based on trip distribution derived from spatial economics. The estimation of modal distribution of trips and land development has been the main focus of integrated land use and transport models. However, no connection with transportation asset management has been established. This paper proposes the use of spatial economic simulation to forecast freight-traffic distribution to improve pavement-deterioration modeling. A case study of trade flows between Canada’s Atlantic Provinces and Québec is used to show the pitfall of current management models in estimating rates of deterioration, underfunding maintenance, and rehabilitation strategies. It was found that a total cost of $25 million could maintain adequate levels of condition under the current performance modeling; however, such a budget is inadequate when performance is based on forecasted truck traffic. It was also found that aggregation of pavements in a few homogeneous groups resulted in the inability to prioritize investments considering the economic relevance of the road in the region. This study suggests the use of individual deterioration models for strategic roads.

Teacher imitation

Not 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.
