Abstract

fetched live from OpenAlex

Technological advancements in recent years have allowed hybrid electric vehicles (HEV) to improve in terms of fuel efficiency and associated tailpipe emissions. As a result, the demand for HEVs in Canada has been on the rise but the market share is still negligible. In this paper, the population of HEVs in the Windsor Census Metropolitan Area (CMA), Ontario, Canada for the year 2011 is considered to study the determinants that led to the observed spatial distribution of this class of vehicles across the different census tracts within the CMA. Vehicle-specific characteristics along with locational variables are employed in the analysis. Locational factors are based on census tract profile attributes (namely socio-economic factors) that were acquired from the 2011 Census National Household Survey (NHS). Other variables used in the analysis include mixed density index and land use heterogeneity. Discrete choice modeling is used to explain the probability of finding HEVs in a specific area. Moran’s I statistics analysis suggests that the spatial distribution of HEVs exhibits a clustering pattern. Locational factors pertaining to the education, type of job, income, age, size of household of the people living in an area where HEVs were observed explain the spatial prevalence of various classes of HEVs. Also, areas with mixed density and heterogeneous land uses tend to give rise to the existence of HEVs.

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.
