What about free-floating carsharing? A look at the Montréal case
Bibliographic record
Abstract
ABSTRACT: In recent years carsharing has become a practical, ecological, and economical alternative to private car ownership all around the world. Traditional carsharing is station-based, but recently new types of shared services have appeared, and one of these is free-floating carsharing. It is more flexible, but what is its impact on user behavior? This paper aims to characterize the use of the free-floating carsharing service in central Montreal (Canada). We compare the use of the traditional, station-based service and the new service. Some people are members of both services, so we are able to examine the specific contribution of each service to meeting travel needs. We also explore the impact of the introduction of this new transportation alternative. The results show that, compared with traditional carsharing, more women are members of the free-floating service, and the trip distances and durations are much shorter. Shopping is the most important activity, and there is a concentration of trip ends near the central business district in the midday period. When asked what mode they would have used in the absence of the free-floating service, the users mentioned public transit, taxis, and walking; the popularity of these alternatives varies, probably in relation to seasonal changes. Further studies are required to measure the environmental impact of this new transportation mode.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
