SHARED-USE VEHICLE SERVICES: A SURVEY OF NORTH AMERICAN MARKET DEVELOPMENTS
Bibliographic record
Abstract
Shared-use vehicle services provide members access to a fleet of vehicles for use throughout the day, without the hassles and costs of individual auto ownership. From June 2001 to June 2002 the paper surveyed 28 North American shared-use vehicle service organizations on a range of topics, including business model approach, organizational size, strategic partnerships, pricing strategies, and technology applications. While survey findings demonstrate a decline in the number of organizational starts between June 2001 and June 2002, the rate of operational launches into new cities, membership, and fleet size continue to increase. Several growth-oriented organizations in Canada and the U.S. are responsible for the majority of this growth and innovation. The paper also noted several factors that could facilitate or inhibit shared-use vehicle market growth in North America, such as high capital investment (or start-up costs), dramatic hikes in insurance rates, grant programs and other supportive public policies, and technology developments.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
