Abstract

fetched live from OpenAlex

The National Road Map Database of Japan has been created and maintained in public private partnership since 1988. The Road Bureau and major car companies have established a very unique system of the Database provision based on road information collection two years before road completion. Therefore many road information services including the public traffic information service as well as the car navigation device production by private companies can take time to be prepared by the road opening. So far the first challenge of the Database has been very successful. Then comes the next challenge for contribution to intelligent transportation systems (ITS). What is the role of road map database to play for advanced ITS applications? Will the public private partnership be successful again in future? Although the answers are still open, the authors are starting preparation for the future in several directions including the location reference system, the road elevation and the lane network.

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.

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.
