Abstract

fetched live from OpenAlex

This research proposes a framework for microsimulation modelling of traffic evacuation, considering persons needing mobility assistance (PMA). The study develops a hybrid approach to evaluate four designated evacuation routes under different network conditions. These routes are incorporated into a microsimulation model utilizing dynamic traffic assignment for regular vehicles and pre-defined assignment for emergency vehicles (EVs). The model executes three traffic conditions under two scenarios to evaluate the Average Evacuation Time (AET) for an EV exiting the Halifax peninsula. The first scenario, ‘Out of Danger Zone' (ODZ), determines AET to exit the peninsula, while the second, ‘To the Shelter Location’ (TSL), evaluates AET to reach designated shelters. The results show that routes 1 and 4 are the fastest under case 3 for both scenarios, while case 2 is the most realistic. Under case 2, route 2 is the fastest for ODZ, and route 1 for TSL. The suggested method supports policymakers in planning PMA evacuations.

Full frame distilled prediction

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.
