Squaring the circle: The BHLS concept
Bibliographic record
Abstract
The transport systems known as Bus Rapid Transit (BRT) was launched in Curitiba, Brazil, in 1974 as a means of offering efficient and effective bus travel within the fast expanding city. This experience, together with other big examples like in Ottawa (since 1983) or in Quito (since 1994), have proven to be an efficient and effective solution to mass transport. \nThroughout Europe similar experiences have started to be developed, but responding to a different concept of quality of service. \nBus systems such as the “trunk network”, in Sweden, the Metrobus, in Germany, or the BHNS (Bus à Haut Niveau de Service), broach the quality of service from a wider perspective than the BRT, as it considers aspects such as image, confort...,apart from speed, frequency or reliability. \nThese new systems - BHLS (Buses with a High Quality of Service) - allow to combine quality of service of tramways with the lower costs and higher flexibility of bus systems, and offers very interesting solutions in terms of accessibility, a wide range of service levels, that allows the system to be adapted to the different urban contexts (size, population, density…) \nIn the economic situation we are now living, the lack of funds provides BHLS an important role in public transport. Less costs with the same quality of service seems to be a very attractive option. \nThe aim of this article is to compare the different European experiences of tramways and BHLS, specially from the economic point of view, considering the costs, benefits and advantages of each of them.

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.
