Abstract

fetched live from OpenAlex

The efficiency of pickup-and-delivery (P&D) activities of urban courier is adversely impacted by traffic congestion and lack of logistical innovations. The high frequency of P&D tasks offers the opportunity to achieve substantial savings in time through the implementation of route optimization, route guidance, and scheduling innovations. These innovations would require the intelligent transportation systems (ITS) technologies for their implementation. This paper describes how such time savings can be obtained. For testing the effect of network and operating conditions on time savings, a simulation study was undertaken on synthesized networks and logistical requirements. The results show that route guidance and scheduling systems yield highly significant time savings in the P&D operation of the courier industry.Key words: courier, intelligent transportation systems, route guidance, route planning, simulation.

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.
