GWR : accidents point and lit/unlit motorway segments.

Any thoughts on how to accurately apply GWR based on point/segment data. I am looking into the correlation btwn road accident severity (pointd) and lit/unlit segments of a motorway.

Most of the reading showed GWR applied on areas and not segments.

Initial considerations:
- dependent variable: centroid of each segment with total crash data weight by severity.
- explanatory variables: accidents data variables (lit/unlit, weather, lanes, speed, gender...)

Could use any help and advice!
Much appreciated.
