Abstract

fetched live from OpenAlex

Weigh-In-Motion (WIM) systems are used for dynamic traffic data collection. These sensors are capable of collecting various truck characteristics such as weights, speed, and dimensions. Alberta Transportation (AT) installed 20 WIM sensors in six different highway sections across Alberta in 2004. The accuracy of these measurements and their effects on pavement design is evaluated in this thesis. To investigate the accuracy of the WIM sensors a verification test was conducted on the sensors from 2004 to 2010. The errors in the WIM sensors’ measurements were estimated. Statistical analysis was performed on the database of errors. Statistical analysis on the verification test program database showed that WIM weight errors do not comply with current standards and there is a need to improve the system. The new predicted pavement performance results from the Mechanistic Empirical Pavement Design Guide (MEPDG) showed that local WIM traffic data inputs should be used for Alberta highways.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
